将Neo4j封装进Agent / ai #55
Neo4j的各项功能跑通了,应该将其封装进Agent做为应用。LangGraph中有专门的ReAct Agent,可将其Neo4j做为一个工具导入,就是一个好用的Agent啰! Agent(由AIJoe生成) from dotenv import dotenv_values from langchain_openai import ChatOpenAI from langchain_neo4j import

知识图谱和图数据库Neo4j的作用和使用场景 / ai #52
相比传统RAG的碎片式的知识点不同,知识图谱就是要解决这个痛点。它更侧重于宏观式的、总括式的归纳。这里要提到的知识图谱的应用是指GraphRAG。 GraphRAG简介 GraphRAG(Graph-based Retrieval-Augmented
