FAQPage Schema
How do I extract chronological events from multiple sources and build a cited timeline?

Yes, you can generate a timeline for investigations by feeding scattered upstream data into the Skill. It applies temporal reasoning to sequence events chronologically and attaches verifiable source citations to produce a validated, structured output.

What is the best way to normalize dates and sequence events chronologically from scattered documents?

The best way to normalize dates is using temporal processing to anchor each event to a specific date. The Skill sequences events from earliest to latest, ensuring chronological accuracy and attaching explicit source citations to the structured output.

Does this timeline extraction tool attach source citations to each event?

Yes, the timeline extraction tool attaches explicit source citations to each event. It extracts chronological events from upstream sources and produces a validated timeline where every entry includes the date, event details, source citation, and a confidence score.

How do I validate temporal data and output a structured timeline for reports?

You validate temporal data by applying temporal reasoning to anchor and sequence events from earliest to latest. The Skill outputs a structured timeline following the AnalysisOutput schema, containing the date, event, source citation, and confidence for each entry.

Can I use upstream data to reconstruct a chronology without manual date sorting?

Yes, you can use upstream data to reconstruct a chronology without manual sorting. The Skill automatically extracts dated events, normalizes the formats, sequences them from earliest to latest, and attaches source citations to produce a validated timeline.
