FAQPage Schema
How do I verify factual claims in a manuscript against existing sources?

Fact-check verifies factual claims in manuscripts by extracting statements, cross-referencing them against ingested database sources, and generating a structured report with reliability scores and confidence levels.

What is the best way to cross-reference research notes for accuracy?

Fact-check cross-references research notes by applying claim extraction and source lookup against your knowledge base, providing verification results and reliability scoring to ensure manuscript accuracy.

Can I use fact-checking for draft chapters across different sections and scenes?

Yes, fact-checking applies to draft chapters across sections and scenes, scanning manuscript content to identify factual claims and verify them against ingested sources for consistency.

How does source verification and reliability scoring work for manuscripts?

Source verification works by matching extracted claims to database sources, assigning reliability scores based on cross-reference matches, and outputting a structured verification report indicating confidence levels.

Do I need to ingest sources into a database before checking manuscript claims?

Yes, you need to ingest sources into the knowledge base database beforehand so fact-check can perform source lookup, cross-reference claims, and generate accurate verification reports.

What are the limitations of automated fact-checking for research verification?

Automated fact-checking is limited to verifying claims against ingested database sources; it cannot verify external claims lacking source matches and relies on the quality and consistency of pre-ingested references.
