+ # How to publish LEGEX to Hugging Face anonymously
2
+
3
+ This walkthrough takes the contents of `submission/` and publishes **three
4
+ public Hugging Face dataset repositories** under the anonymous account
5
+ `legexbenchmark`:
6
+
7
+ 1. **`legexbenchmark/goldensets`** — expert-coded gold annotations
8
+ (19 jurisdictions, 1,548 judgments / 1,974 rows incl. secondary
9
+ re-annotations).
10
+ 2. **`legexbenchmark/inference-results`** — Harvey (2 runs) / Gemini / GPT /
11
+ Legora (2 runs) outputs (19 jurisdictions × 6 runs = 114 files, JSONL)
12
+ plus the per-column prompts of the commercial runs (`prompts/`, 4 files).
13
+ 3. **`legexbenchmark/code`** — Python pipeline (scrape → process → infer →
14
+ clean → evaluate).
15
+
16
+ > **All data files are JSONL** (one JSON object per line). Inference was CSV
17
+ > in the first release and is now JSONL — see *Updating an existing release*
18
+ > below.
19
+
20
+ ---
21
+
22
+ ## 0. Updating an existing release (goldensets + inference-results)
23
+
24
+ The three repos already exist, and local clones live in
25
+ `../hf-uploads/{goldensets,inference-results,code}`. The staged bundle
26
+ (`submission/goldensets/`, `submission/inference-results/`) mirrors the two
27
+ data repos 1:1: data + the per-repo dataset card (`README.md`).
28
+
29
+ Rebuild the bundle only if the underlying data changed
30
+ (`convert_goldenset_to_jsonl.py` needs the local-only
31
+ `data/reannotation/annotators.json` + `ANNOTATOR_SALT` from `.env`):
32
+
33
+ ```bash
34
+ uv run python submission/convert_goldenset_to_jsonl.py --data-dir data --out-dir submission/goldensets/data
35
+ (cd submission && uv run python build_inference_jsonl.py --data-dir ../data --gold-dir goldensets/data --out-dir inference-results/data)
36
+ ```
37
+
38
+ When the working trees in `../hf-uploads/` are already synced from
39
+ `submission/` (data + README copied in, stale CSVs removed), pushing the
40
+ update is:
41
+
42
+ ```bash
43
+ # Log in once with the anonymous account's WRITE token.
44
+ pip install --upgrade huggingface_hub && git lfs install --skip-repo
45
+ huggingface-cli login # paste the hf_… write token
46
+ huggingface-cli whoami # must print: legexbenchmark
47
+
48
+ # --- goldensets ---
49
+ cd ../hf-uploads/goldensets
50
+ git status && git diff --stat # review: data/<cc>/*.jsonl + README.md
51
+ git config user.name anonymous && git config user.email anonymous@anonymous.invalid
52
+ git add -A
53
+ git commit -m "Update: re-annotations, Nepal/Singapore extensions, traceability fields, refreshed card"
54
+ git push
55
+ cd -
56
+
57
+ # --- inference-results (CSV -> JSONL) ---
58
+ cd ../hf-uploads/inference-results
59
+ git status # review: CSVs deleted, 57 JSONL added, README.md, .gitattributes
60
+ git config user.name anonymous && git config user.email anonymous@anonymous.invalid
61
+ git add -A
62
+ git commit -m "Switch inference to JSONL; 19 jurisdictions; cleaning provenance; refreshed card"
63
+ git push
64
+ cd -
65
+ ```
66
+
67
+ Then **verify usability** (the old CSV raised `ArrowInvalid`):
68
+
69
+ ```python
70
+ from datasets import load_dataset
71
+ load_dataset("legexbenchmark/goldensets", split="brazil")
72
+ load_dataset("legexbenchmark/inference-results", "harvey", split="united_states")
73
+ load_dataset("legexbenchmark/inference-results", "gpt", split="switzerland")
74
+ ```
75
+
76
+ Also confirm on the web UI that every commit author reads **`anonymous`**, the
77
+ dataset viewer renders both repos, and no `inference_*.csv` remain in
78
+ `inference-results`.
79
+
80
+ **`code`** is updated separately once the cleaned analysis package is staged —
81
+ see item 3 of [CHANGES_SINCE_SUBMISSION.md](CHANGES_SINCE_SUBMISSION.md).
82
+
83

84
+
85
+ ## 1. Create the anonymous Hugging Face account (once)
86
+
87
+ 1. Open a private / incognito browser window so cookies from any existing
88
+ HF account are isolated.
89
+ 2. Visit <https://huggingface.co/join>.
90
+ 3. Sign up with a **fresh email address** that is not tied to any of the
91
+ authors (a `proton.me` / `tutanota.com` mailbox works fine).
92
+ 4. Pick the username **`legexbenchmark`** so the public URLs match the
93
+ names used in the paper.
94
+ 5. Verify the email and log in.
95
+
96
+ > **Why a fresh account?** HF attaches your account's display name, avatar
97
+ > and email to commits in each repo's history. Reusing an existing account
98
+ > would leak your identity even if every file in the repo is clean.
99
+
100
+ ## 2. Create a write-scoped access token (once)
101
+
102
+ 1. Visit <https://huggingface.co/settings/tokens>.
103
+ 2. Click **New token**, name it `upload`, role **Write**, click **Generate
104
+ token**, copy the value (it starts with `hf_`).
105
+
106
+ ## 3. Install the tooling and log in (once)
107
+
108
+ ```bash
109
+ pip install --upgrade huggingface_hub
110
+ git lfs install --skip-repo # macOS: brew install git-lfs first
111
+
112
+ # Paste the write token created in step 2 when prompted.
113
+ huggingface-cli login
114
+ ```
115
+
116
+ ## 4. Push the three repositories (initial release)
117
+
118
+ Run steps 4a → 4c **in order**. Each step is independent — if something
119
+ breaks in 4b you can fix it without redoing 4a.
120
+
121
+ ### 4a. Push `legexbenchmark/goldensets`
122
+
123
+ ```bash
124
+ # 1. Create the empty repo via the web UI:
125
+ # https://huggingface.co/new-dataset
126
+ # Owner: legexbenchmark | Name: goldensets | License: MIT | Public
127
+
128
+ # 2. Clone, anonymise local git, copy in the staged files.
129
+ git clone https://huggingface.co/datasets/legexbenchmark/goldensets hf-goldensets
130
+ cd hf-goldensets
131
+ git config user.name "anonymous"
132
+ git config user.email "anonymous@anonymous.invalid"
133
+ git lfs track "*.jsonl"
134
+ git add .gitattributes
135
+
136
+ cp -R ../submission/goldensets/. .
137
+
138
+ # 3. Commit and push.
139
+ git add .
140
+ git commit -m "Initial release"
141
+ git push -u origin main
142
+ cd ..
143
+ ```
144
+
145
+ Open <https://huggingface.co/datasets/legexbenchmark/goldensets>. Verify:
146
+
147
+ - The dataset card renders with the jurisdiction tables.
148
+ - `data/<cc>/goldenset_<cc>.jsonl` is browsable for all 19 jurisdictions.
149
+ - The author next to every commit is **`anonymous`**.
150
+
151
+ ### 4b. Push `legexbenchmark/inference-results`
152
+
153
+ ```bash
154
+ # 1. Create the empty repo:
155
+ # https://huggingface.co/new-dataset
156
+ # Owner: legexbenchmark | Name: inference-results | License: MIT | Public
157
+
158
+ # 2. Clone, anonymise, copy in.
159
+ git clone https://huggingface.co/datasets/legexbenchmark/inference-results hf-inference
160
+ cd hf-inference
161
+ git config user.name "anonymous"
162
+ git config user.email "anonymous@anonymous.invalid"
163
+ git lfs track "*.jsonl"
164
+ git add .gitattributes
165
+
166
+ cp -R ../submission/inference-results/. .
167
+
168
+ # 3. Commit and push.
169
+ git add .
170
+ git commit -m "Initial release"
171
+ git push -u origin main
172
+ cd ..
173
+ ```
174
+
175
+ Verify on <https://huggingface.co/datasets/legexbenchmark/inference-results>:
176
+
177
+ - 19 `data/<cc>/` folders (all jurisdictions).
178
+ - Each folder has `inference_harvey.jsonl`, `inference_gemini.jsonl`,
179
+ `inference_gpt.jsonl` (no `.csv`).
180
+
181
+ ### 4c. Push `legexbenchmark/code`
182
+
183
+ ```bash
184
+ # 1. Create the empty repo:
185
+ # https://huggingface.co/new-dataset
186
+ # Owner: legexbenchmark | Name: code | License: MIT | Public
187
+ # (HF dataset repos accept arbitrary files — we use "dataset" type as
188
+ # the most permissive container for source code.)
189
+
190
+ # 2. Clone, anonymise, copy in the cleaned package (see
191
+ # CHANGES_SINCE_SUBMISSION.md item 3 for what goes into the code repo).
192
+ git clone https://huggingface.co/datasets/legexbenchmark/code hf-code
193
+ cd hf-code
194
+ git config user.name "anonymous"
195
+ git config user.email "anonymous@anonymous.invalid"
196
+
197
+ # 3. Commit and push.
198
+ git add .
199
+ git commit -m "Initial release"
200
+ git push -u origin main
201
+ cd ..
202
+ ```
203
+
204
+ Verify on <https://huggingface.co/datasets/legexbenchmark/code>:
205
+
206
+ - The repo card lists the CLI entrypoints and the workflow.
207
+ - `legex/scrapers/` contains 19 jurisdiction modules.
208
+
209
+ ## 5. Cross-verify the org page
210
+
211
+ Open <https://huggingface.co/legexbenchmark> in a fresh tab — you should
212
+ see three pinned datasets. Click each card and confirm:
213
+
214
+ - The README renders correctly.
215
+ - The "Files and versions" tab is browsable.
216
+ - No identifying information appears next to commits (everything should
217
+ read `anonymous`).
218
+
219
+ Also run one final string search per repo via the file viewer for your own
220
+ surname, your affiliation, and your work email domain:
221
+
222
+ ```
223
+ <your-surname> # must return nothing
224
+ <your-affiliation> # must return nothing
225
+ <your-email-domain> # must return nothing
226
+ ```
227
+
228
+ ## 6. Share with reviewers
229
+
230
+ The single URL that ties the three repos together is
231
+ <https://huggingface.co/legexbenchmark>. Add it to the supplementary
232
+ material of your OpenReview submission; reviewers can browse all three
233
+ datasets from that org page without logging into HF.
234
+
235
+ ---
236
+
237
+ ## Troubleshooting
238
+
239
+ **A commit shows your real name despite the local config.** Run
240
+ `git log -1 --pretty='%an <%ae>'` inside the clone. If it still shows your
241
+ real identity, redo `git config user.name / user.email` and then
242
+ `git commit --amend --reset-author` before pushing.
243
+
244
+ **HF complains about LFS quota.** Free accounts get 1 GB of LFS storage;
245
+ this release uses ~30 MB so quota is not a concern.
246
+
247
+ **A file exceeds 5 GB.** None of the files in this release do. If a future
248
+ addition does, `git lfs track` the path and recommit.
249
+
250
+ **You want to delete a repo.** Each repo's Settings page has "Delete this
251
+ dataset repository" — that removes files and history.
252
+
253
+ **You need to re-push after a fix.** `cd` into the local clone, edit, commit
254
+ with `--reset-author` if you also re-ran `git config`, then `git push`.
255
+
256
+ **Reviewers ask for a single zip.** HF's "Use this dataset" → "Repository
257
+ size" → "Download repository" gives a `.tar.gz` of the whole repo.

+ # LEGEX — Reproduction Bundle (release/icml2026)
2
+
3
+ LEGEX is an expert-coded benchmark for civil-judgment review-table
4
+ extraction: judgments from the highest civil courts of 19 jurisdictions,
5
+ annotated by legal experts on a shared schema (monetary outcomes, cost
6
+ allocation, party structure, industry classification), against which we
7
+ evaluate two commercial review-table systems (Harvey, Legora) and two
8
+ schema-constrained LLM pipelines (Gemini, ChatGPT). This bundle is the
9
+ versioned code + data payload behind the paper LEGEX: An Eight-Jurisdiction
10
+ Benchmark for Legal Review-Table Extraction (ICML 2026 Workshop on AI for
11
+ Law). It contains an eight-jurisdiction core benchmark (≥100 judgments each,
12
+ double-annotated on a 28–30-case overlap) and eleven preview jurisdictions.
13
+
14
+ The release consists of three Hugging Face repositories, pinned to the
15
+ `release/icml2026` branch:
16
+
17
+ | Artifact | Contents | URL |
18
+ |---|---|---|
19
+ | `goldensets` | Expert gold labels, `data/<cc>/goldenset_<cc>.jsonl` | <https://huggingface.co/datasets/legexbenchmark/goldensets/tree/release/icml2026> |
20
+ | `inference-results` | System predictions, `data/<cc>/inference_{harvey,harvey_2,gemini,gpt,legora_1,legora_2}.jsonl`, plus the as-run per-column prompts of the commercial runs in `prompts/` | <https://huggingface.co/datasets/legexbenchmark/inference-results/tree/release/icml2026> |
21
+ | `code` | This bundle (package, scripts, shipped analysis outputs) | <https://huggingface.co/datasets/legexbenchmark/code/tree/release/icml2026> |

+
58
+ ## Reproduce the paper tables and figures
59
+
60
+ All commands are run **from this directory** (the bundle root). Requires
61
+ [uv](https://docs.astral.sh/uv/) and Python ≥ 3.11.
62
 
63
  ```bash
 
 
64
  uv sync
 
65
  ```
66
 
67
+ **Table `tab:overall` (headline metrics).** Re-render from the shipped
68
+ per-cell aggregate and check it is byte-identical to the shipped table:
69
 
70
+ ```bash
71
+ uv run legex-quant-results --input data/analysis/per_country_per_column.csv --out /tmp/quant_results.tex
72
+ diff /tmp/quant_results.tex data/analysis/quant_results.tex
73
+ ```
74
+
75
+ **Tables `tab:metrics-by-jurisdiction` and `tab:metrics-by-field`.**
76
 
77
  ```bash
78
+ uv run python scripts/paper_tables.py > /tmp/paper_tables.tex
79
+ diff /tmp/paper_tables.tex data/analysis/paper_tables.tex
80
+ ```
81
 
82
+ **IAA / kappa / Alternative Annotator Test report** (`ANALYSIS.md`, the
83
+ source of the paper's `tab:iaa` and AAT numbers). The report is rendered
84
+ purely from the shipped CSVs:
85
 
86
+ ```bash
87
+ uv run legex-analysis-report --iaa-dir data/analysis/iaa --analysis-dir data/analysis --out /tmp/ANALYSIS.md
88
+ diff /tmp/ANALYSIS.md data/analysis/iaa/ANALYSIS.md
89
+ ```
90
 
91
+ **One-shot reproduction.** `scripts/reproduce_paper.sh` regenerates every
92
+ artifact under `data/analysis/` — IAA CSVs, scoring aggregates, all tables,
93
+ the diversity/frequency figures, the hallucination shares, and `ANALYSIS.md`
94
+ — from the published bundles in `goldensets/data/` and
95
+ `inference-results/data/`. The run is byte-stable, so a clean
96
+ `git status data/analysis` afterwards is the verification that the shipped
97
+ numbers reproduce:
98
 
99
+ ```bash
100
+ bash scripts/reproduce_paper.sh
101
+ git status data/analysis
 
102
  ```
103
 
104
+ ## Unpublished ata
105
+
106
+ The expert-annotated XLSX workbooks (`data/<cc>/Goldenset_*_final*.xlsx`)
107
+ behind the goldensets arenot published: Microsoft Office embeds author
108
+ metadata, and the re-annotation assignment structure could identify
109
+ individual annotators. The gold labels are published in full as
110
+ `goldensets/data/<cc>/goldenset_<cc>.jsonl` with primary + anonymized secondary
111
+ annotator rows, and every analysis in this bundle runs from those published
112
+ files, the workbooks are not needed for reproduction.
113
+
114
+ ## Alternative Annotator Test (AAT).
115
+ The AAT (Calderon, Reichart & Dror,
116
+ ACL 2025, [arXiv:2501.10970](https://arxiv.org/abs/2501.10970)) is run with
117
+ the authors' original implementation via the adapter
118
+ `scripts/alt_test_reference.py`, which extracts `alt_test()` from the
119
+ upstream notebook at runtime and feeds it LEGEX data from the published
120
+ bundles:
121
 
122
  ```bash
123
+ git clone https://github.com/nitaytech/AltTest /tmp/AltTest
124
+ ALTTEST_DIR=/tmp/AltTest bash scripts/reproduce_paper.sh # or:
125
+ uv run python scripts/alt_test_reference.py --alttest /tmp/AltTest \
126
+ --gold-dir goldensets/data --inference-dir inference-results/data \
127
+ [--countries ge,sg,tw] [--epsilon 0.2] [--out data/analysis/iaa] [--per-field]
128
  ```
129
 
130
+ Its outputs (`alt_test_pooled.csv`, `alt_test_reference_*.csv`) are shipped
131
+ under `data/analysis/iaa/` and rendered into `ANALYSIS.md` by
132
+ `legex-analysis-report`.
133
 
134
+ ## Scraping
135
+
136
+ The scrapers that built the corpus are included (`legex/scrapers/`, one file
137
+ per jurisdiction; see `docs/Jurisdictions.md` for the per-country catalogue).
138
+
139
+ ```bash
140
+ cp .env.template .env
141
+ uv run legex-run
142
+ ```
143
+
144
+ `legex-run` executes the idempotent pipeline (scrape → filter/sample →
145
+ fill goldenset → dist) for every registered jurisdiction and skips countries
146
+ whose access is not set up or whose output already exists. Some sources need
147
+ manual prerequisites (all keys go into `.env`, see
148
+ [.env.template](.env.template)):
149
+
150
+ - **Hugging Face** (`au`, `ch`, `de`, `us`): a read token as `HF_TOKEN`;
151
+ `de` and `us` additionally require accepting the gated-dataset terms of
152
+ `openlegaldata/court-decisions-germany` and
153
+ `free-law/Caselaw_Access_Project`.
154
+ - **France**: register at <https://piste.gouv.fr>, subscribe to the
155
+ Judilibre API, set `JUDILIBRE_CLIENT_ID` / `JUDILIBRE_CLIENT_SECRET`.
156
+ - **New Zealand**: copy the WAF cookie from a justice.govt.nz session into
157
+ `NZ_WAF_COOKIE`.
158
+ - **India**: `legex-india-extract` pulls selected PDFs from the AWS Open
159
+ Data TAR archives (see `legex/scrapers/in_.py`).
160
+
161
+ Model inference over the scraped full texts (the paper runs use prompt v3):
162
+
163
+ ```bash
164
+ uv run legex-classify --model <model> --full_text --prompt_version v3
165
+ ```
166
+
167
+ Tests: `uv run pytest -q`.

10
+
11
+ - Countries with ≥2 annotators: **8** — br, ch, de, ge, sg, tw, uk, us
12
+ - Annotators: **11** (primary + 10 secondary: 359f544380, 40dd94f4cc, 5c9b11ec0c, 93839740f5, 9bbad8ca9e, ab2d3cfed5, b36683f5be, c7cd8dc26a, cf5a561621, dd79b903af)

+ ## 2. Human–human agreement
18
+
19
+ > **Per-variable agreement.** Percent agreement is reported for every variable, using the same value-matching as the evaluation (ISO-date / number-format aware; `0` and empty treated alike). For the two **nominal ISIC** fields — the only variables with a fixed controlled vocabulary — we additionally report **Cohen's κ**. For the other variables the category space is unbounded (free text) or continuous (dates, counts, money, ratios): there κ's chance correction collapses toward percent agreement (as the number of categories → ∞, expected agreement pₑ → 0 and κ → observed agreement) and awards no partial credit for near-misses, so percent agreement is the appropriate summary. Correlation coefficients are deliberately not used — for these labels a wrong value is wrong, not partially correct. Cell detail: `kappa_audit.csv`.
20
+
21
+ _n = paired case comparisons (shared cases × annotator pairs). We report ±1 SE = √(p(1-p)/n) in percentage points, a descriptive precision marker. This is not a significance test._

81
+ ## 3. Alternative-annotator test
82
+
83
+ > **Alternative Annotator Test** (Calderon et al. 2025, [arXiv:2501.10970](https://arxiv.org/abs/2501.10970)): leave each human annotator out in turn and score, per instance, both the candidate and the excluded annotator against the remaining annotators; a one-sided test per annotator asks whether the candidate's advantage probability trails the human's by less than ε = 0.2 (the expert-annotator tolerance), under Benjamini–Yekutieli FDR control at q = 0.05. `passes` = winning rate ≥ 0.5. Requires ≥ 3 independent annotators per country; free-text fields are excluded. ρ is the advantage probability — how likely the candidate annotates as well as or better than a randomly chosen human. The *non-trivial* variant drops instances every expert left empty: an empty prediction ties those for free, so the gap between the two columns shows how much of a pass rests on empty cells. Untestable cells (too few non-empty judgements) are excluded from the denominators.
84
+ >
85
+ > These numbers come from the **authors' reference implementation** ([github.com/nitaytech/AltTest](https://github.com/nitaytech/AltTest)) executed on the LEGEX data via `scripts/alt_test_reference.py`. See the README section "Alternative Annotator Test (AAT)" for how to run it. `legex-iaa` does not produce these CSVs.
86
+
87
+ ### 3.1 How ω and ρ are computed
88
+
89
+ _Definitions from Calderon et al. (2025), as implemented in the authors' `alt_test`.
90
+ `values_agree` is the tolerant comparator LEGEX passes in as the scoring function._
91
+
92
+ ```text
93
+ One jurisdiction, one candidate f, human annotators H = {1..M}, and instances i
94
+ (here: one (judgment, variable) cell over the 10 structured fields).
95
+
96
+ LEAVE-ONE-OUT. For human j and every instance i the other humans also labelled,
97
+ let A(i,-j) be the remaining humans' labels and
98
+
99
+ s_f(i,j) = score( f(i), A(i,-j) ) candidate vs. the other humans
100
+ s_h(i,j) = score( h_j(i), A(i,-j) ) held-out human vs. the same humans
101
+
102
+ score(p, A) = (1/|A|) * SUM_{a in A} values_agree(p, a) in {0, 1/2, 1}
103
+
104
+ ADVANTAGE PROBABILITY of the candidate against human j. Note the ">=", which
105
+ credits every tie to the candidate:
106
+
107
+ rho_j = (1/n_j) * SUM_i 1[ s_f(i,j) >= s_h(i,j) ]
108
+
109
+ PER-ANNOTATOR TEST. With d_i = 1[s_f < s_h] - 1[s_f >= s_h], so E[d] = 1 - 2*rho_j:
110
+
111
+ H0: E[d] >= epsilon vs. H1: E[d] < epsilon
112
+
113
+ one-sided paired t-test (Wilcoxon signed-rank when n_j < 30), the M p-values
114
+ corrected by Benjamini-Yekutieli at q = 0.05. Rejecting H0 is therefore
115
+ equivalent to rho_j being significantly greater than
116
+
117
+ (1 - epsilon) / 2 = 0.4 for the expert tolerance epsilon = 0.2
118
+
119
+ VERDICT.
120
+
121
+ omega = |{ j : H0_j rejected }| / M winning rate
122
+ rho = (1/M) * SUM_j rho_j advantage probability
123
+ "f may substitute a human annotator" <=> omega >= 0.5
124
+ ```
125
+
126
+ Two consequences worth keeping in view when reading §3.2. First, ρ is a
127
+ **≥**-comparison, so a candidate that merely matches the held-out human on an
128
+ instance is scored as winning it. Second, with ε = 0.2 the hypothesis test
129
+ clears at ρ_j > 0.4, not at 0.5. Both are deliberate: the alt-test asks whether
130
+ a candidate can *substitute* a human annotator, not whether it is *better* than
131
+ one. §3.4 separates the two.
132
+
133
+
134
+ ### 3.2 Headline: pooled per jurisdiction (paper numbers)
135
+
136
+ _One alt-test per jurisdiction; instance = (judgment, variable) cell over the 10 structured fields, so each annotator contributes ~190+ effective instances and the paired t-test applies without the paper's n<30 caveat._

+ ### 3.4 Substitutable vs. better: win / tie / loss decomposition
192
+
193
+ > ρ collapses the leave-one-out comparison of §3.1 into one number, and its `≥` hands every tie to the candidate. This section keeps the same comparisons and reports the counts instead: per held-out human and instance, whether the candidate scored **better than**, **the same as**, or **worse than** that human against the two remaining humans. Restricted to judgments all three experts labelled, so every comparison has exactly two references and a score is 0, ½ or 1. `ρ (alt-test)` is the reproduced advantage probability (ties → candidate); `ρ (ties split)` counts a tie as half a win for each side. Source: `alt_test_decomposition.csv` from `scripts/alt_test_decomposition.py`, which reproduces the reference ρ of §3.2 to within 0.02.

241
+ **What is in the “Tie” bucket.** A tie only means *same score against the same two references*, so it merges several different situations. Split by score level, and independently by whether the candidate actually produced the held-out expert's answer:
242
+
243
+ | Candidate | Ties | Same answer as expert | Different answer, equal score | at 1 (all agree) | at ½ (experts conflict) | at 0 (both differ) |

250

251
+ A tie at ½ is only possible when the two reference experts contradict each other — that caps every achievable score at ½, for the candidate and the held-out expert alike. The two references disagree in 1543 of 5640 comparisons (27%; a property of the human labels, identical for every candidate). Note that reference disagreement is *not* the same thing as a tie: ties also arise, and in fact more often, where the two references agree and the candidate simply matches them.

254
+
255
+ - **gemini-3.1-flash-lite** — 77% of the 5640 comparisons are ties. 87% of those ties are real agreement (candidate gave the held-out expert's answer); the other 13% are comparisons where candidate and expert gave *different* answers that happened to score the same, and ρ credits every one of them to the candidate. On the 1302 comparisons that actually discriminate, the human wins 63% (821 vs 481). Dropping instances whose reference is empty throughout leaves ρ (ties split) at 0.46.
256
+ - **gpt-5.4-mini** — 76% of the 5640 comparisons are ties. 85% of those ties are real agreement (candidate gave the held-out expert's answer); the other 15% are comparisons where candidate and expert gave *different* answers that happened to score the same, and ρ credits every one of them to the candidate. On the 1353 comparisons that actually discriminate, the human wins 66% (899 vs 454). Dropping instances whose reference is empty throughout leaves ρ (ties split) at 0.47.
257
+ - **harvey** — 77% of the 5640 comparisons are ties. 90% of those ties are real agreement (candidate gave the held-out expert's answer); the other 10% are comparisons where candidate and expert gave *different* answers that happened to score the same, and ρ credits every one of them to the candidate. On the 1284 comparisons that actually discriminate, the human wins 54% (690 vs 594). Dropping instances whose reference is empty throughout leaves ρ (ties split) at 0.48.
258
+ - **legora-1** — 75% of the 5010 comparisons are ties. 92% of those ties are real agreement (candidate gave the held-out expert's answer); the other 8% are comparisons where candidate and expert gave *different* answers that happened to score the same, and ρ credits every one of them to the candidate. On the 1255 comparisons that actually discriminate, the human wins 60% (749 vs 506). Dropping instances whose reference is empty throughout leaves ρ (ties split) at 0.45.
259
+ - **legora-2** — 75% of the 5010 comparisons are ties. 92% of those ties are real agreement (candidate gave the held-out expert's answer); the other 8% are comparisons where candidate and expert gave *different* answers that happened to score the same, and ρ credits every one of them to the candidate. On the 1256 comparisons that actually discriminate, the human wins 60% (748 vs 508). Dropping instances whose reference is empty throughout leaves ρ (ties split) at 0.45.
260
+
261
+ This is what the alt-test is and is not evidence for. The tie rate is high and mostly genuine, so on this data the models are largely *indistinguishable* from an additional expert — which is exactly the substitutability claim ω and ρ are designed to support, and §3.2 supports it. It is not evidence of superiority: once ties stop counting as wins, ρ sits at chance, and on the comparisons that separate the two the human expert is still ahead. "Can this model replace a human annotator?" and "is this model better than a human annotator?" are different questions, and only the first one is being tested.

+ ## 4. Headline extraction metrics
264
+
265
+ > Recall = TP / (TP + Mismatch + Missed) over cells the expert filled; precision = TP / (TP + Mismatch + Hallucinated); hallucination = invented values on empty-gold cells. Buckets from `legex/evaluation.py`; per-cell source `../per_column.csv`. n = evaluated label cells; recall and precision carry ±1 SE over their gold-filled / emitted denominators. The per-field grids (§4.2–4.5) break each metric out by variable across models; their `n` is the metric's model-independent denominator (gold-filled for recall, gold-empty for hallucination) and is omitted for precision (emitted; model-dependent) and F1 (composite).

358
+ - Alt-test: authors' reference implementation ([github.com/nitaytech/AltTest](https://github.com/nitaytech/AltTest)) run via `scripts/alt_test_reference.py` → `alt_test_reference_*.csv` (see README).
359
+ - Alt-test win/tie/loss decomposition: `scripts/alt_test_decomposition.py` → `alt_test_decomposition.csv`.
360
+ - Tolerant comparator: `legex/evaluation/comparison.py` (`values_agree`, `normalise`).
361
+ - Headline buckets: `legex/analysis/aggregate.py` over `legex/evaluation.score_country`.
362
+ - This report: `legex/analysis/report.py`.

3
+ Research catalogue for scaling `legex` to new jurisdictions. Each row is a
4
+ candidate country/court, what data source we'd use, how to isolate civil-law
5
+ cases, and how hard the scraper looks. Two jurisdictions are already
6
+ implemented; the others are prioritised into waves.
7
+
8
+ Source links and contact names come from GitHub issue
9
+ [#3](https://github.com/Engineers-for-Science-Initiative/legex/issues/3) and
10
+ Daniel's compilation table. Link checks and source research were performed
11
+ via WebFetch/WebSearch; HuggingFace datasets were preferred where available.

49
+
50
+ ### Wave 1 — implement next
51
+
52
+ - United Kingdom — Supreme Court (BAILII)
53
+
54
+ - Link: https://www.bailii.org/uk/cases/UKSC/
55
+ - Sample: https://www.bailii.org/uk/cases/UKSC/2024/24.html
56
+ - Civil filter: all UKSC decisions are civil/mixed; filter by year and case topic.
57
+ - Auth: none; free, no cookies, no anti-bot.
58
+ - Scraper: scrape `bailii.org/uk/cases/UKSC/<year>/` index pages; follow per-case HTML or PDF. ~100–150 civil cases/year 2015–2025. Stable structure.
59
+ - Australia — High Court
60
+
61
+ - Link: https://www.hcourt.gov.au/cases-and-judgments/judgments
62
+ - HF dataset: `isaacus/high-court-of-australia-cases` (also `isaacus/open-australian-legal-corpus`).
63
+ - Civil filter: case-type classification; HCA mixes civil and constitutional.
64
+ - Scraper: reuse the HF parquet path, same pattern as CH. Trivial.
65
+ - Austria — Oberster Gerichtshof (RIS)
66
+
67
+ - Link: https://www.ris.bka.gv.at
68
+ - Sample: https://www.ris.bka.gv.at/Dokumente/Justiz/JJT_20241024_OGH0002_0010OB00161_24V0000_000/
69
+ - Civil filter: senate codes like `Ob` for civil revision.
70
+ - Auth: none; German only.
71
+ - Scraper: query RIS by date+senate, paginate by case number.
72
+
73
+ ### Wave 2 — moderate effort
74
+
75
+ - Germany — Bundesgerichtshof Zivilsenate
76
+
77
+ - Link: https://juris.bundesgerichtshof.de
78
+ - Civil filter: case prefix `ZR` (Zivilrecht) across senates I–XII.
79
+ - Auth: none (scraping BGH is legal per 2024 precedent).
80
+ - Scraper: parse `cgi-bin/rechtsprechung/document.py`; ~300 decisions/year civil.
81
+ - Armenia — Court of Cassation
82
+
83
+ - Link: https://www.cassationcourt.am/en/precedent/civil-cases-advanced-search
84
+ - Civil filter: already has a dedicated civil-cases advanced-search form.
85
+ - Auth: none. Armenian / English / Russian UI.
86
+ - Scraper: POST the advanced-search form, parse results table.
87
+ - United States — SCOTUS (via CourtListener)
88
+
89
+ - Official portal: https://www.supremecourt.gov/opinions/USReports.aspx (mixed civil/criminal, no filter).
90
+ - Preferred: CourtListener API (courtlistener.com/api) or HF "Pile of Law".
91
+ - Civil filter: apply post-hoc via case-type classification (SCOTUS cases are mostly certiorari; filter by case topic).
92
+ - Auth: CourtListener has free API keys with rate limits.
93
+ - Scraper: CourtListener API `/api/rest/v3/opinions/?court=scotus`.
94
+ - New Zealand — High Court + Court of Appeal
95
+
96
+ - Link: https://www.justice.govt.nz/courts/decisions/jdo/
97
+ - Civil filter: "Civil" dropdown in JDO search.
98
+ - Auth: none. 3-day publication lag.
99
+ - Scraper: JDO search form, paginate, follow per-case HTML.
100
+ - Hong Kong — Court of Final Appeal + High Court
101
+
102
+ - Link: https://legalref.judiciary.hk/lrs/common/ju/judgment.jsp
103
+ - Civil filter: court level + case type dropdowns (civil/criminal).
104
+ - Scraper: GET-based search form, fairly mechanical.
105
+ - Singapore — Supreme Court + SICC
106
+
107
+ - Link: https://www.judiciary.gov.sg/judgments/judgments-case-summaries
108
+ - Civil filter: case summaries classified as civil vs criminal; SICC (commercial, 2015+) is a separate civil-only feed.
109
+ - Scraper: two feeds — general Supreme Court + SICC.
110
+
111
+ ### Wave 3 — special challenges
112
+
113
+ - Korea: scourt.go.kr, case designation `Da` = civil appellate. Hangul full-text.
114
+ - India: sci.gov.in, PDF-heavy; free-text "civil appeal" search. Multiple scripts possible.
115
+ - Philippines: elibrary.judiciary.gov.ph, chronological monthly index, DataTables pagination.
116
+ - Brazil: scon.stj.jus.br — "Pesquisa Pronta" is curated themes; verify whether the themed set is representative of civil cases or only a subset.
117
+ - Dominican Republic: poderjudicial.gob.do — First Chamber (Civil + Commercial). Spanish.
118
+ - Georgia: supremecourt.ge — AJAX modals; needs Playwright/Selenium rather than requests.
119
+ - Kazakhstan: sud.gov.kz — Bank of Judicial Acts, filter by case type. Kazakh/Russian/English.
120
+ - Ukraine: reyestr.court.gov.ua — case form "Цивільні справи". Anti-bot protection, "test mode" warnings; rate-limit gently.
121
+
122
+ ### Wave 4 — calendar / script conversion required
123
+
124
+ - Taiwan: judgment.judicial.gov.tw is an ASP.NET form (stateful POST + cookies). Case-type filter `民事` (civil). Year input is ROC calendar (民國 N = Gregorian N+1911). Example: ROC 113 = 2024.
125
+ - Nepal: nkp.gov.np uses Bikram Sambat calendar (~57 years ahead; 2015 AD ≈ 2072 BS). Nepali-Unicode-only search form. Calendar conversion helper required.
126
+
127
+ ### Blocked / investigate later
128
+
129
+ - Italy — italgiure.giustizia.it is subscription-gated. Investigate whether the research group can obtain institutional access or negotiate bulk-export terms. No public bulk download.
130
+ - Spain — poderjudicial.es CENDOJ prohibits bulk use (>100/day = ToS breach). Only ~147 Supreme Court civil cases since 2017 meet the Sala de lo Civil filter — insufficient for a 130-sample Goldenset unless we find alternative CENDOJ OpenData access.
131
+ - China — wenshu.court.gov.cn requires Chinese mobile-phone registration and has aggressive anti-bot. Consider the NYU Shanghai Library snapshot or the CAIL2018 civil-cases dataset before attempting live scraping.
132
+ - Belarus — court.gov.by only publishes Plenum explanations (non-binding jurisprudence) in the official gazette "Sudovy vestnik". No structured civil-decision database.
133
+
134
+ ## Key observations
135
+
136
+ 1. Seven jurisdictions are HuggingFace-ready or have usable public APIs (CH, FR already done; AU via `isaacus/high-court-of-australia-cases`; UK via BAILII; US via CourtListener). These are cheapest to implement and should be the next tickets.
137
+ 2. Most mid-tier countries are HTML scrapes with a dedicated civil filter at source (Austria, Germany, Belgium, Armenia, NZ, HK, Singapore, Dominican Republic). Each is ~1–2 days of scraper work.
138
+ 3. Four countries are effectively blocked without a policy change or alternative source (Italy, Spain, China, Belarus). Flag these to Adrian / Nerea / Jelle / contacts for guidance rather than burning engineering time.
139
+ 4. Non-Gregorian calendars and non-Latin scripts affect Taiwan (ROC), Nepal (Bikram Sambat), and the CJK countries. These need conversion utilities before scraping; consider a shared `legex/utils/calendar.py` when the first non-Gregorian jurisdiction ships.
140
+ 5. Prioritise "civil filter at source" over post-hoc filtering. Countries where the court already exposes a civil-only search (Armenia, Belgium C-prefix, Austria N Ob, Germany ZR) produce high-precision Goldensets with minimal noise.

+ # LEGEX Goldensets: Expert-Coded Review-Table Annotations
118
+
119
+ This repository contains the expert-coded gold annotations for the LEGEX
120
+ benchmark of civil-judgment review-table extraction. 1,548 judgments across
121
+ 19 jurisdictions have been annotated by hand against a shared 14-field schema
122
+ covering monetary outcomes, cost allocation, party structure, and industry
123
+ classification. Including independent secondary re-annotations, the release
124
+ holds 1,974 annotation rows.
125
+
126
+ ## Dataset summary
127
+
128
+ Legal review-table systems are increasingly used to extract structured facts
129
+ from judgments, but there is little public evidence on their reliability in
130
+ cross-jurisdictional legal settings. LEGEX is an expert-coded benchmark for
131
+ civil-judgment review-table extraction. The current release contains an
132
+ eight-jurisdiction core benchmark with at least 100 judgments per jurisdiction,
133
+ each coded by two or more independent experts on a 28–30 case overlap and
134
+ eleven preview jurisdictions for testing schema portability. The re-annotated
135
+ overlap enables inter-annotator agreement (IAA) analysis on the core set.
136
+
137
+ The word cloud below shows the topical spread of the free-text
138
+ `legal_subject_judgement` labels over all annotated judgments (underscores
139
+ stripped, stopwords and generic terms such as "law" removed):
140
+
141
+ ![Word cloud of the normalized legal-subject labels](assets/legal_subject_wordcloud.png)
142
+
143
+ ## Schema
144
+
145
+ Each line in `data/<cc>/goldenset_<cc>.jsonl` is a JSON object with these
146
+ keys:
147
+
148
+ | Key | Type | Description |
149
+ |-----|-----|---------------------------------------------------------------------------------------------------------------------------------|
150
+ | `case_id` | string | Identifier within the source database. |
151
+ | `link` | string | URL to the original judgment. |
152
+ | `full_text` | string \| null | Full judgment text used as model input. |
153
+ | `legal_subject_judgement` | string | Short English subject of the case. Acts as the "this row has been substantively reviewed" marker. |
154
+ | `trial_start_date` | YYYY-MM-DD \| null | Trial start date. |
155
+ | `trial_end_date` | YYYY-MM-DD \| null | Decision date. |
156
+ | `dispute_value_nominal` | string \| null | Amount in dispute as a string (e.g. `"150000"`) or the literal `"nonpecuniary"`. |
157
+ | `Currency_dispute_value_nominal` | string \| null | ISO-4217 currency code. |
158
+ | `plaintiff_loosing_share` | number [0, 1] \| null | Plaintiff's losing share. |
159
+ | `court_cost_awarded_nominal` | number \| null | Court fees awarded. |
160
+ | `Currency_court_cost_awarded_nominal` | string \| null | ISO-4217 currency code. |
161
+ | `party_compensation_awarded_nominal` | number \| null | Party compensation awarded. |
162
+ | `Currency_party_compensation_awarded_nominal` | string \| null | ISO-4217 currency code. |
163
+ | `plaintiffs_all_count` | integer \| null | Number of plaintiffs. |
164
+ | `defendants_all_count` | integer \| null | Number of defendants. |
165
+ | `plaintiff_no1_ISIC1_industry_category` | string \| null | ISIC Section A–U for the first plaintiff. |
166
+ | `defendant_no1_ISIC1_industry_category` | string \| null | ISIC Section A–U for the first defendant. |
167
+
168
+ A row is included when `legal_subject_judgement` is populated (the marker the
169
+ annotator used to flag a row as substantively reviewed). Cells left empty by
170
+ the annotator are stored as `null`. In the raw JSONL the trial dates are
171
+ `YYYY-MM-DD` strings. The declared dataset features type them as `date32`, so
172
+ the `datasets` library returns them as date objects.
173
+
174
+ ### Traceability fields
175
+
176
+ Every record additionally carries provenance fields so each value is
177
+ auditable:
178
+
179
+ | Key | Type | Description |
180
+ |-----|-----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
181
+ | `annotator_id` | string | Pseudonymous, salted-hash id of the coder, stable per person across jurisdictions. |
182
+ | `comment` | string \| null | Human-readable note listing every field changed during sanitization, e.g. `"The trial_end_date was sanitized from '2026_03_19' to '2026-03-19'."`, `null` when the record needed no change. |
183
+ | `original_input` | string | JSON object mapping each changed field to its 1:1 pre-sanitization value, `"{}"` when nothing changed. This lets any consumer reconstruct the raw value. |
184
+
185
+ ### Primary and secondary annotations
186
+
187
+ Jurisdictions that received an independent re-annotation contain both the
188
+ primary annotator's rows and the secondary annotators' rows, distinguished by
189
+ `annotator_id`. Within each file all primary rows come first and re-annotation
190
+ rows are appended after them, so **the first row per `case_id` is the primary
191
+ gold annotation**. For benchmark evaluation, deduplicate to the primary rows.
192
+ For inter-annotator agreement, group the duplicated `case_id`s by
193
+ `annotator_id`.

+

249
+ Total: 1,548 expert-coded judgments, 1,974 annotation rows.
250
+
251
+ Core benchmark (≥ 100 expert-coded judgments, coded by ≥ 2 independent
252
+ annotators): Brazil, Georgia, Germany, Singapore, Switzerland, Taiwan,
253
+ United Kingdom, United States. In each core jurisdiction 28–30 cases were
254
+ independently re-annotated by one or two additional experts.
255
+ Preview jurisdictions: the remaining eleven (Armenia, Australia, Belgium,
256
+ France, Hong Kong, India, Nepal, New Zealand, Philippines, Serbia, Spain).
257
+ Nepal reaches 130 cases but is single-annotated and therefore remains
258
+ preview.
259
+
260
+ ## Loading
261
+
262
+ ```python
263
+ from datasets import load_dataset
264
+
265
+ # Single jurisdiction
266
+ ds = load_dataset("legexbenchmark/goldensets", split="switzerland")
267
+ ds = load_dataset("legexbenchmark/goldensets", split="united_states")
268
+
269
+ # All jurisdictions
270
+ from datasets import concatenate_datasets
271
+ splits = [
272
+ "armenia", "australia", "belgium", "brazil", "france", "georgia",
273
+ "germany", "hong_kong", "india", "nepal", "new_zealand", "philippines",
274
+ "serbia", "singapore", "spain", "switzerland", "taiwan",
275

276
+ ]
277
+ all_rows = concatenate_datasets([
278
+ load_dataset("legexbenchmark/goldensets", split=s) for s in splits
279
+ ])
280
+ ```
281
+
282
+ ## Limitations
283
+
284
+ - Sample sizes: Nine of the nineteen jurisdictions have fewer than 100
285
+ expert-coded judgments; Nepal and Spain reach 100+ cases but are
286
+ single-annotated. These eleven are marked as preview and intended for
287
+ schema-portability checks rather than per-jurisdiction performance claims.
288
+ - Time coverage: Source databases vary considerably (Georgia and Taiwan are
289
+ 2026-only because earlier years were not freely available).
290
+ - Schema portability: the 14 fields were designed against civil judgments
291
+ in common-law and Western European civil-law systems. Some fields
292
+ (e.g. `plaintiff_loosing_share`, ISIC categorisation) may not be a natural
293
+ fit for every jurisdiction.
294
+ - Court selection: For Brazil, there are judgements that are not from the
295
+ highest possible court. This can be inferred with the case id. The Spain
296
+ goldenset draws mainly on the Tribunal Constitucional and the Tribunal
297
+ Económico-Administrativo Central rather than the Tribunal Supremo (Sala de
298
+ lo Civil); the court can likewise be inferred from the case_id.
299
+ - Full-text quality: Text was extracted from heterogeneous sources (HTML,
300
+ PDF, API JSON). Layout artefacts and OCR errors are possible.
