# Memory Question Answering on WorldLines Memory QA samples Source: [Memory Question Answering on WorldLines Memory QA samples]() Collection index: [llms.txt]() Data updated: 2026-06-18T08:15:00.573Z Evaluation of Memory Question Answering performance on the WorldLines Memory QA samples dataset, utilizing metrics such as Judge, Perfect score, and session-based retrieval scores. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Memory Question Answering | | Dataset (including any stated split) | WorldLines Memory QA samples | | Metric | Judge Score | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 5 of 5 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Judge Score](): Higher is better; unit: PERCENT. - [Perfect Score](): Higher is better; unit: PERCENT. - [Session Any@5](): Higher is better; unit: PERCENT. - [Event R@5](): Higher is better; unit: PERCENT. - [StateMH-J](): Higher is better; unit: PERCENT. - [StateMH-E](): Higher is better; unit: PERCENT. - [StateSH-J](): Higher is better; unit: PERCENT. - [Temp-J](): Higher is better; unit: PERCENT. ## Recorded results | Method | Judge Score | Result date | Report paper | | --- | --- | --- | --- | | ObsMem | 71.3 | Not recorded | 6a337b82206542251d7c4fc6 | | A-mem | 57.5 | Not recorded | 6a337b82206542251d7c4fc6 | | Mem0 | 55.4 | Not recorded | 6a337b82206542251d7c4fc6 | | GraphMem | 45.7 | Not recorded | 6a337b82206542251d7c4fc6 | | MemoryOS | 31.2 | Not recorded | 6a337b82206542251d7c4fc6 | ### ObsMem Judge Score: 71.3.
