TKG-RAG: A Retrieval-Augmented Generation Framework with Text-chunk Knowledge Graph

A retrieval-augmented generation framework that utilizes a text-chunk knowledge graph to improve performance.

The authors propose TKG-RAG, a framework that constructs a text-chunk knowledge graph automatically from domain text. This framework improves Retrieval-Augmented Generation (RAG) performance by addressing limitations such as noise and redundant information in retrieved text chunks. Comparative experiments show that TKG-RAG achieves better accuracy and F1 scores while reducing token consumption.

Enhancing Knowledge Graph Completion with Retrieval-Augmented Generation Using Large Language Models

A study introducing a framework for Knowledge Graph Completion using Large Language Models and Retrieval-Augmented Generation.

The authors propose an innovative framework for Knowledge Graph Completion leveraging Large Language Models. The framework treats KG triples as textual prompts to retrieve relevant information from knowledge bases, generating contextually accurate responses. A retrieval reranking strategy refines predictions by incorporating outputs from a pre-trained KGC model.
