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
- Upstream file:
longmemeval_s_cleaned.json - Upstream revision:
98d7416c24c778c2fee6e6f3006e7a073259d48f - Upstream file SHA-256:

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% |

57 | 11.4% |

| 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.

Validation
- Both inputs contain 500 unique
question_idvalues, with identical ID sets. question_typeand question time match for all 500 records.- Every corrected evidence ID exists in the corresponding
haystack_session_idslist. - The generated file contains 500 unique records and retains every non-target value from the upstream dataset.
