The authors propose SimGRAG, a two-stage process that aligns query texts and KG structures using an LLM to transform queries into a desired graph pattern. They also develop an optimized retrieval algorithm.

Experiments show that SimGRAG outperforms state-of-the-art methods in question answering and fact verification.

Abstract

The authors propose SimGRAG, a two-stage process that aligns query texts and KG structures using an LLM to transform queries into a desired graph pattern. They also develop an optimized retrieval algorithm. Experiments show that SimGRAG outperforms state-of-the-art methods in question answering and fact verification.
