Temporal QA

QA: Question Answering

Ask about this topic

Overview

Temporal question answering studies questions that require locating events in time, comparing intervals, tracking changes, or identifying what was true at a specified date. Approaches include temporal knowledge graphs, interval-algebra rules and automata, retrieval over versioned documents and structured memories, and timestamped evidence selection for video and audio. Benchmarks span knowledge-graph tasks such as TimeQA and MultiTQ, evolving legal and policy documents, time-series analysis, and long-video understanding. A central challenge is grounding answers in the right temporal evidence: language models often rely on stale knowledge or miss version boundaries, while retrieval and structured reasoning improve reliability but can add cost and still struggle with complex evidence.
