Entity Knowledge Graph

Introduction

CogMem automatically extracts named entities — people, projects, concepts, tools, places — from ingested documents and builds a knowledge graph of relationships between them. Entity Dossier workflows generate Wikipedia-style pages with claims and evidence for any entity in the graph.

Challenges

• Extracting entities accurately from diverse document types.
• Resolving entity aliases and deduplication across sources.
• Building meaningful relationships between entities.
• Generating useful dossiers from claims and evidence.

Solution

The EntityExtractAgent uses LLM-powered extraction to identify entities from passages. Entities are linked into a knowledge graph with typed relationships. The Entity Dossier workflow gathers all claims about an entity, hydrates supporting evidence, and renders a comprehensive dossier artifact.
