Diffbot's NLP API allows for the extraction of entities, relationships, and semantic meaning from unstructured text data.
By coupling Diffbot's NLP API with Neo4j, a graph database, you can create powerful, dynamic graph structures based on the information extracted from text.
These graph structures are fully queryable and can be integrated into various applications.from langchain.graphs import Neo4jGraphfrom langchain_experimental.graph_transformers.diffbot import DiffbotGraphTransformerFor a more detailed walkthrough generating graphs from text, see documentationPreviousMyScaleNextNLPCloudInstallation and SetupWrappersVectorStoreGraphCypherQAChainConstructing a knowledge graph from textCommunityDiscordTwitterGitHubPythonJS/TSMoreHomepageBlogCopyright ¬© 2023 LangChain, Inc.
