Researchers have developed AdaPath, a novel framework designed to improve path-finding for multi-hop question answering over biomedical knowledge graphs. This method addresses challenges specific to the biomedical domain, such as queries that don't explicitly reveal intermediate reasoning steps and densely connected knowledge graphs that can lead to incorrect paths. AdaPath utilizes a 'Path-Bank' to retrieve query-adaptive meta-paths, effectively guiding reasoning and pruning irrelevant information. The framework has demonstrated consistent outperformance on biomedical KGQA benchmarks and is accompanied by the release of BioStrat-QA, a new benchmark for evaluating multi-hop biomedical queries.
