Cover Story: In information retrieval (IR), the semantic gap represents the mismatch between users’ queries and how retrieval models answer these queries. In this paper, we explore how to use external knowledge resources to enhance bag-of-words representations and reduce the effect of the semantic gap between queries and documents. In this regard, we propose several simple but effective knowledge-based query expansion and reduction techniques, and evaluate them in relation to the medical domain. The experimental analyses on different test collections for precision medicine IR show the effectiveness of the developed techniques. In particular, a specific subset of query reformulations allows retrieval models to achieve top-performing results in all the considered test collections. View this paper
