MIR: Methodology Inspiration Retrieval for Scientific Research Problems

The paper introduces Methodology Inspiration Retrieval (MIR), a novel approach to retrieving prior research that can inspire solutions for new scientific problems by leveraging a Methodology Adjacency Graph (MAG) capturing citation-based methodological lineage. Their method significantly improves retrieval performance over strong baselines and, combined with LLM-based re-ranking, shows promise for enhancing automated scientific discovery through inspiration-driven literature retrieval.
