DOTRAG: Retrieval-Time Reasoning Along Paths
The paper introduces DotRAG, a new framework for Graph Retrieval-Augmented Generation that reformulates retrieval as a reasoning process. This approach aims to improve performance on complex multi-hop tasks by generating query-conditioned constraints that guide graph exploration. DotRAG has demonstrated state-of-the-art performance on benchmarks like MetaQA and UltraDomain.
- ▪DotRAG is a training-free framework that enhances the retrieve-then-reason paradigm in GraphRAG.
- ▪The framework generates constraints that help in exploring relevant relational paths while pruning irrelevant areas.
- ▪DotRAG has achieved state-of-the-art performance on multiple benchmarks, particularly in multi-hop tasks.

Such methods struggle to adapt to the query-specific logic required for complex multi-hop tasks, often accumulating irrelevant context or missing correct relational paths.
