MemoryDocDataSet: A Benchmark for Joint Conversational Memory and Long Document Reasoning

arXiv:2606.04442v1 Announce Type: cross Abstract: AI systems increasingly need to combine two demanding capabilities: navigating multi-session conversation history and performing deep reading comprehension within long documents. Yet no existing benchmark evaluates both simultaneously. We introduce MemoryDocDataSet, a synthetic benchmark of 50 micro-worlds and 1,000 QA pairs in which each instance comprises 3-5 personas, a temporal event graph spanning months of activity, 3-5 real long documents (20,000-50,000 tokens each sourced from the Caselaw Access Project), multi-session conversations gro

Why this matters
Why now

The increasing sophistication of large language models and attention mechanisms necessitates more complex benchmarks that reflect real-world, multi-faceted cognitive tasks.

Why it’s important

This new benchmark represents a critical step towards developing AI agents capable of sustained, context-aware reasoning over long periods and extensive data, moving beyond single-turn queries.

What changes

The introduction of MemoryDocDataSet shifts the goalposts for AI evaluation by simultaneously testing conversational memory and deep document comprehension, pushing research towards more integrated AI capabilities.
