A nice case to analyze would be assigning to the main process an instance such as EC2 G4 that is specially prepared for ML inference with lots of GPU processing power, and in conjunction with the hability of GraphRagSDK to integrate OLlama models, a self hosted LLM instance would be ...
微软研究人员选取了两个数据集用来对Graph RAG进行评测,分别是播客对话记录和新闻集锦两个日常生活中非常常见的主题。 对于问题的形式,由于传统的评测数据集他们的query主要关注语料库中的细节内容,与Graph RAG的目标形式不符,所以研究人员进一步设计了自己提问自己的评测方式。对于一个数据集,给定数据集描述,让LLM识别可...
In this paper, we present a Graph RAG approach based on global summarization of an LLM-derived knowledge graph (Figure 1). In contrast with related work that exploits the structured retrieval and traversal affordances of graph indexes (subsection 4.2), we focus on a previously unexplored quality ...

Our approach uses an LLM to build a graph-based text index in two stages: first to derive an entity knowledge graph from the source documents, then to pregenerate community summaries for all groups of closely-related entities. Given a question, each community su...
GraphRAG is a technique that uses large language models (LLMs) to create knowledge graphs and summaries from unstructured text documents and leverages them to improve retrieval-augmented generation (RAG) operations on private datasets. It offers comprehensive ...
The expressive power and effectiveness of large language models (LLMs) is going to increasingly push intelligent agents towards sub-symbolic models for nat

使用Neo4j和LangChain实现“Local to Global”的GraphRAG GraphRAG是一种基于知识图谱的检索增强技术。它使用多来源数据构建图模型的知识表达,将实体和关系之间的联系以图的形式展示,然后利用大语言模型进行检索增强。这种方法能更高效准确地检索相关信息,并为LLM生成响应提供更好的上下文。微软和领英的技术人员已经科学的...
