NuBerea Features

Pre-analytical feature extraction outputs for the NuBerea corpus: Stanza lemma/lexicon/syntax tables for patristic Greek and Latin, SPhilBerta/PhiloBERTa embeddings for patristic segments and biblical verses, and PhiloBERTa lexical alignment primitives. Consolidates configs formerly in NuBerea/patristics-features, NuBerea/concept-primitives, and NuBerea/greek-embeddings-primitives.

Configs

Patristic Greek / Latin — Syntax

Config	Rows	Key Columns
`grc_syntax`	78,209	`segment_id`, `source`, `cts_urn`, `author_label`, `finite_verb_rate`, `max_dep_depth`, `subordinate_clause_rate`
`lat_syntax`	145,559	`segment_id`, `source`, `cts_urn`, `author_label`, `finite_verb_rate`, `max_dep_depth`, `subordinate_clause_rate`

Relocated (not in this dataset): grc_lemmas, grc_lexicon, lat_lemmas, lat_lexicon were moved out of features by k-remediation (2026-06-23) and now live in the isolation repo NuBerea/quarantine-derivatives (license:other, do-not-redistribute), with a verified byte-identical copy in NuBerea/patristics-features (grc_* = 98,872 rows, lat_* = 145,559 rows). Their lemma_text / tokens reconstruct restricted catlib (PD-Migne PG/PL) source text, so they are not redistributed here. The *_syntax configs above ship only aggregate stats (no reconstructable text) and remain.

Patristic Embeddings

Config	Rows	Key Columns
`patr_grc_embeddings_sp`	40,176	`segment_id`, `cts_urn`, `family_id`, `author_label`, `work_label`, `embedding` (SPhilBerta 768-dim)
`philoberta_alignment`	20,992	`lang_pair`, `strong_a`, `strong_b`, `lemma_a`, `lemma_b`, `angular_sim`, `low_freq_flag`

Biblical Verse Embeddings

Config	Rows	Model	Key Columns

NHC LN Bridge

LN domain codes transferred from NT verse embeddings to Nag Hammadi Corpus segments via cosine KNN (k=5) in SPhilBerta embedding space. vote_confidence = top-voted LN weight / total weight.

Source Repos (Deprecated)

Former Repo	Configs Absorbed
`NuBerea/patristics-features`	`grc_syntax`, `lat_syntax` (absorbed) — `grc_lemmas`, `grc_lexicon`, `lat_lemmas`, `lat_lexicon` were relocated to `NuBerea/quarantine-derivatives`, not absorbed (see Configs note)

Methodology — patristic SPhilBerta embeddings (`patr_grc_embeddings_sp`, `patr_lat_embeddings_sp`)

Both configs embed patristic segments with bowphs/SPhilBerta (Riemenschneider & Frank 2023, arXiv:2308.13116), a sentence-transformer trained jointly on Latin, Ancient Greek, and English. The same encoder is used for both languages by design: it places Greek and Latin segments in a single shared vector space, so cross-language concept comparison (e.g. a Cyril of Alexandria Greek passage vs. an Augustine Latin passage) is meaningful. Using a language-specific encoder for either side would break that comparability.

Config	Lang	Rows	Source configs (patristics-pta/csel/canonical/catlib split repos)	Dim
`patr_grc_embeddings_sp`	grc	40,176	patristic Greek segments	768
`patr_lat_embeddings_sp`	lat	141,137	`lat_segments`, `catlib_lat_segments`, `catlib_orig_lat`	768

Build (Latin, 2026-06):

Pull Latin patristic segments from the three source configs on the patristics-* split repos (pta/csel/canonical/catlib; patristics-texts was retired 2026-06-24).
Unicode-NFC normalize; keep segments with Latin-script purity ≥ 0.80 (drops language-mislabels, critical-apparatus contamination, stray non-Latin characters). 146,293 → 141,137 segments.
Join reconciliation metadata (cts_urn, author_label, work_label) from the canonical author/work registry by segment_id.
Encode with SPhilBerta (batch 64) on Apple-Silicon MPS; 768-dim sentence vectors, un-normalized.

Schema (both configs): segment_id, cts_urn, cts_group_urn, family_id, author_label, work_label, text, lang, embedding (768-d float), model_id.

Parity note: patr_lat_embeddings_sp is the Latin counterpart built under the project's Greek/Latin parity rule — every patristic feature built for one language is built for the other. Latin coverage (141k) exceeds Greek (40k) because the Latin patristic corpus (Augustine, Ambrose, Tertullian, Cyprian, Jerome, …) is larger in segment count.

Rabbinica-derived morphology configs (2026-08-30) — license envelope note

The repo license tag moved cc-by-4.0 → cc-by-sa-4.0: it is the most-restrictive ENVELOPE of the configs now present, per the estate's rabbinica precedent. True per-config provinces:

config	rows	k (true province)	source text
mishnah_features	313,412	public-domain	rabbinica/mishnah (Romm Vilna 1913)
tosefta_features	273,128	cc-by-4.0	rabbinica/tosefta_lieberman
tosefta_vilna_kodashim_tahorot_features	151,520	cc-by-sa-4.0	rabbinica/tosefta_vilna_kodashim_tahorot (he.wikisource)
targum_arc_lexicon	527,019	cc-by-sa-4.0	rabbinica six targum configs (text_arc)

yerushalmi_ln_bridge_rabbinica	12,243	cc-by-4.0	rabbinica/yerushalmi (Guggenheimer CC-BY en leg) — first clean Yerushalmi LN bridge, C1 2026-09-01

All four are original-language (Hebrew/Aramaic) surfaces; zero English. ShareAlike modification notice: SA-province source text is tokenized/annotated into row-per-word parquet; attribution and verbatim license ride the source rows in NuBerea/rabbinica. ⚠ targum_arc_lexicon reproduces the incumbent's NULL annotation surface faithfully (all rows oov — the TAHOT-keying producer defect is documented in build/features/RECEIPT_C1_2026-08-30.md); do not wire anything assuming it carries MACULA annotation. Pre-existing configs' provinces are unchanged by the tag move.
