Veracity Reveals the Sources Behind Its AI Fact Checks With 0-100% Reliability Scores

Veracity is an open-source fact-checking system from Montreal’s Complex Data Lab that pairs a large language model with a web retrieval agent and refuses to answer without showing its evidence. Every claim comes back as a reliability score between 0% and 100%, a plain-English interpretation, a share recommendation gated at 60%, and a panel listing every source consulted along with its documented credibility. This breakdown covers the five-stage pipeline, the stack behind it, why the 60% cutoff is the most questionable decision in the design, what independent benchmarks say about the roughly 83% real-world accuracy ceiling for automated fact-checking, and how to evaluate any claim-scoring layer before you let it near a workflow.

RAG Chunking and Parsing: Proven Fixes for Better Answers

Retrieval systems are judged on their answers but built on their chunks. This guide covers the two steps that create them: parsing, which turns a file into usable text, and chunking, which cuts that text into the units your index stores. It compares fixed, recursive, structure-aware and semantic splitting, sets out workable size and overlap ranges, explains the metadata that turns a search result into a citable answer, handles the document types that defeat generic splitting, and shows how to measure retrieval with a gold question set before you trust it.
