利用知識圖譜與Llama-Index技術構建大模型驅動的RAG系統（下）
7、構建知識圖譜索引
#setuptheservicecontext service_context=ServiceContext.from_defaults( chunk_size=256, llm=llm, embed_model=embed_model ) #setupthestoragecontext graph_store=SimpleGraphStore() storage_context=StorageContext.from_defaults(graph_store=graph_store) #ConstructtheKnowlegeGraphUndex index=KnowledgeGraphIndex.from_documents(documents=documents, max_triplets_per_chunk=3, service_context=service_context, storage_context=storage_context, include_embeddings=True)
8、從文檔中創建知識圖譜

10、可視化表示
frompyvis.networkimportNetwork fromIPython.displayimportdisplay g=index.get_networkx_graph() net=Network(notebook=True,cdn_resources='in_line',directed=True) net.from_nx(g) net.show('graph.html') net.save_graph('Knowledge_graph.html') # importIPython IPython.display.HTML(filename='/content/Knowledge_graph.html')
11、持久化保存
storage_context.persist()
總結
對于語言模型（LLM）幻覺，知識圖譜被證明優于向量數據庫。知識圖譜提供更準確、多樣化、有趣、邏輯和一致的信息，減少了LLM中出現幻覺的可能性。這種優越性源于它們能夠提供關于實體之間關系的精確細節，而不僅僅是表示相似性，支持更復雜的查詢和邏輯推理。
向量數據庫以其數字數組在相似性搜索和最佳匹配場景中表現出色。最終，兩者之間的選擇取決于項目的需求，包括數據的性質、關系探索的需要以及預期的查詢類型。

知識圖譜與大模型結合方法概述
本文作者 |? 黃巍 《Unifying Large Language Models and Knowledge Graphs: A Roadmap》總結了大語言模型和知識圖譜融合的三種路線：1
利用知識圖譜與Llama-Index技術構建大模型驅動的RAG系統（上）
向量數據庫是一組高維向量的集合，用于表示實體或概念，例如單詞、短語或文檔。向量數據庫可以根據實體或概念的向量表示來度量它們之間的相似性或關聯性。
知識圖譜與大模型之間的關系
在人工智能的廣闊領域中，知識圖譜與大模型是兩個至關重要的概念，它們各自擁有獨特的優勢和應用場景，同時又相互補充，共同推動著人工智能技術的發展。本文將從定義、特點、應用及相互關系等方面深入探討知
