Given the remarkable semantic understanding capabilities of large language models (LLMs), this paper proposes a novel KGR model using LLMs augmented GNNs (LGKGR), which aims to utilize LLMs to enhance the graph structure learning of GNNs. Each round of reasoning includes three stages: path ...
Neo4j开源了基于LLM提取知识图谱的生成器:llm-graph-builder https://github.com/SuperMedIntel/Medical-Graph-RAG https://github.com/circlemind-ai/fast-graphrag 论文提出了一种新的Graph RAG方法,结合了知识图谱生成、检索增强生成(RAG)和查询聚焦摘要(QFS),以支持对整个文本集合的人类感知。通过构建基于实体的...
“Knowledge graphs provide the perfect complement to LLM-based solutions where high thresholds of accuracy and correctness need to be attained.” Gartner Research: AI Design Patterns for Knowledge Graphs and Generative AI, June 2023 “Using an LLM-generated knowledge graph … vastly improves the retr...
For example, LLMs have token limits, which restrict the input and output number of words that can be included. This approach eliminates this problem by using the LLMs to build the query/prompt and using the knowledge graph to query. Since SPARQL queries can query gigabytes of data, they do...
Knowledge Graph as Condensed(浓缩的) Information Storage 大多数使用 LLM 来回答我们遇到的多跳问题的新方法都集中在查询时解决任务。但是,我们认为,许多多跳问答问题可以通过在引入之前对数据进行预处理并将其连接到知识图谱中来解决。可以使用 LLM 或自定义文本域模型来进行信息提取pipeline。 为了在查询时从知识图...
查询知识图谱通常需要与存储系统(如 Cypher)相关的特定领域知识。但是,在 LLM 和 LlamaIndex KnowledgeGraphQueryEngine 的帮助下,这可以通过自然语言来实现! 知识图谱查询引擎(KnowledgeGraphQueryEngine)是一个查询引擎,允许我们使用自然语言查询知识图谱。它使用 LLM 生成 Cypher 查询,然后在知识图谱上执行。这样,我们就...
This may involve linearizing the graph or embedding the structured data into text prompts. Response Generation: The LLM generates a response using both the original query and the contextual information from the knowledge graph. The generated output is expected to be more accurate, with reduced chance...
