Precision Medicine (PM) is regarded as an information retrieval (IR) task, in which biomedical articles containing treatment information about specific diseases or genetic variants are retrieved in response to patient record, aiming at providing medical evidence to the point-of-care. In existing PM approaches,manual keywords such as treatment and therapy are considered direct indicators of treatment information, and are there by introduced to expand the original query. However, the common medical concepts that are implicitly related to treatment (such as oncogene, tumor), and differ the relevant documents from the non-relevant ones, are yet to be utilized. To bridge the gap, in this paper, we propose an extension of the state of-the-art neural information retrieval (NIR) models, including K-NRM and DRMM, to encapsulate the PM solutions withina neural network framework, coined as NIRPM. Specifically,the proposed approach mines a global list of common medical concepts from documents that are judged pertinent to different queries. Thereafter, the mined implicit concepts are incorporated within a neural IR framework to enhance the effectiveness of precision medicine. Experimental results on the standard Text Retrieval Conference (TREC) PM track benchmark confirm the superior performance of the proposed NIRPM model.
