Entity Extraction

The process of identifying and categorizing key information (entities) within unstructured text, enabling structured data representation for downstream applications like RAG (Retrieval-Augmented Generation).

Key Applications:

• Extracting entities (e.g., people, organizations, concepts) and relationships from documents
• Powering Knowledge Graph construction for enhanced semantic search
• Improving rag system accuracy by grounding queries in extracted entity relationships

Recent Integration:

• Cocoindex data transformation framework enables real-time knowledge graph construction from markdown documents using LLMs for entity/relationship extraction
• Uses Neo4j as the graph database backend
• Video tutorial: Building Knowledge Graphs with LLMs and Cocoindex
• Project goal: Establish document-to-knowledge graph pipelines for dynamic rag knowledge bases
