Too Long; Didn't ReadThis article explores the implementation of a "From Local to Global" GraphRAG pipeline using Neo4j and LangChain. It covers the process of constructing knowledge graphs from text, summarizing communities of entities using Large Language Models (LLMs), and enhancing Retrieval-...
Knowledge graphGoogle searchTriples extractionCo-reference resolutionNatural language processingMost data in the world is in form of text. Therefore, we can say text stores large amount of the knowledge of human beings. Extracting useful knowledge from text, however, is not a simple task. In this...
权重向量可用来分离首部/尾部实体中的正负实例。 尾部关系学习 关系抽取可看作是一个分类问题。 不同的关系之间共享一些共同的语法和词法结构。 因此,不同关系的分类问题视为相关联的任务, 故可以使用多任务迁移学习(Multi-task Transfer Learning)技术来进行关系抽取。 联合优化 由于实体和关系是高度相关联的,所以将...
