| # LongMemEval ReMe Cleaned-S |
|
|
| `longmemeval_s_reme_cleaned.json` is a corrected version of the LongMemEval |
| Cleaned-S dataset. It keeps the original questions and haystack sessions while |
| replacing the answer and supporting-session ground truth with the reviewed |
| values from `final_groundtruth_cleaned_s.json`. |
|
|
| The corrections address inaccurate answers and evidence sessions, including |
| cases where evidence occurred after the question time and therefore leaked |
| future information into the evaluation. |
|
|
| ## Sources |
|
|
| - Upstream dataset: [xiaowu0162/longmemeval-cleaned](https://huggingface.co/datasets/xiaowu0162/longmemeval-cleaned) |
| - Upstream file: `longmemeval_s_cleaned.json` |
| - Upstream revision: `98d7416c24c778c2fee6e6f3006e7a073259d48f` |
| - Upstream file SHA-256: `d6f21ea9d60a0d56f34a05b609c79c88a451d2ae03597821ea3d5a9678c3a442` |
| - Reviewed ground-truth SHA-256: `97dd2b0df872f12c682041c44fe8082f9fa55ab882f5c78c9237b7c77ba9bb00` |
| - Generated dataset SHA-256: `f8b308cc2d184d029dd2226e0c0a88eeac298e6318706d588e015beb1b83fc7d` |
|
|
| ## Transformation |
|
|
| Records are matched one-to-one by `question_id`. The generated file preserves |
| the upstream schema and applies these mappings: |
|
|
| | Output field | Value | |
| | --- | --- | |
| | `answer` | Reviewed `answer` | |
| | `original_answer` | Upstream `answer` | |
| | `answer_session_ids` | Reviewed `evidence_session_ids` | |
| | `original_answer_session_ids` | Upstream `answer_session_ids` | |
|
|
| The reviewed `evidence_session_ids` are written to `answer_session_ids` so the |
| result remains compatible with the upstream Cleaned-S format. All other |
| fields, including `question`, `question_date`, `question_type`, |
| `haystack_sessions`, `haystack_session_ids`, and `haystack_dates`, are retained |
| from the upstream records. |
|
|
| ## Change statistics |
|
|
| Changes are counted using exact JSON value equality. |
|
|
| | Metric | Records | Share | |
| | --- | ---: | ---: | |
| | Total | 500 | 100.0% | |
| | Any corrected field changed | 77 | 15.4% | |
| | No corrected field changed | 423 | 84.6% | |
| | `answer` changed | 57 | 11.4% | |
| | `answer_session_ids` changed | 58 | 11.6% | |
| | Both fields changed | 38 | 7.6% | |
| | Only `answer` changed | 19 | 3.8% | |
| | Only `answer_session_ids` changed | 20 | 4.0% | |
|
|
| Evidence-session totals changed from 948 to 819. The corrections removed 129 |
| evidence references across 58 records and added none. Records with an empty |
| evidence list increased from 0 to 58; all 58 corrected records with empty |
| evidence use an answer beginning with `The information provided is not enough.` |
|
|
| | Question type | Total | Answer changed | Evidence changed | Either changed | |
| | --- | ---: | ---: | ---: | ---: | |
| | `knowledge-update` | 78 | 2 | 6 | 8 | |
| | `multi-session` | 133 | 7 | 11 | 17 | |
| | `single-session-assistant` | 56 | 0 | 0 | 0 | |
| | `single-session-preference` | 30 | 4 | 0 | 4 | |
| | `single-session-user` | 70 | 1 | 0 | 1 | |
| | `temporal-reasoning` | 133 | 43 | 41 | 47 | |
|
|
| ## Validation |
|
|
| - Both inputs contain 500 unique `question_id` values, with identical ID sets. |
| - `question_type` and question time match for all 500 records. |
| - Every corrected evidence ID exists in the corresponding |
| `haystack_session_ids` list. |
| - The generated file contains 500 unique records and retains every non-target |
| value from the upstream dataset. |
