Programming Knowledge Graphs with Python: Model, Build, and Query AI-Ready Knowledge with Cypher, Neo4j, and AI Agents by Ryein Twardo
Requirements: .ePUB reader, 4 mb
Overview: Get practical hands-on to build your own knowledge graph, and use it across retrieval, analytics and agents
LLMs sound confident, but they forget context, invent facts and can’t show their reasoning. A knowledge graph gives them structured, traceable facts to work from. What you’ll do in this book is grow a single Neo4j graph from the Python Enhancement Proposals, which are the documents that shaped the language. It starts with getting to grips with nodes and relationships and writing Cypher like a pro. Then you design a schema in Pydantic, chunk documents into a lexical graph and extract entities with spaCy and local LLMs. Then, you add vector embeddings and indexes, and combine full-text search, vector search and graph traversal into GraphRAG retrieval that cites its sources.
The rest of the book goes into more detail. You can rank and cluster nodes with Graph Data Science, infer new facts with rules, import ontologies and validate data with SHACL. You also give LangGraph agents guarded Cypher tools, serve the graph over MCP, store agent memory with Graphiti and trace every decision. At the end of the day, you keep the graph healthy with regular refreshes, time-bound facts, evaluation runs, query tuning and backups.
