CBIA VT at TREC 2015 Clinical Decision Support Track - Exploring Relevance Feedback and Query Expansion in Biomedical Information Retrieval
نویسندگان
چکیده
We present the description and results of our participation in the Clinical Decision Support track at TREC 2015. In this task, our goal was to use clinical narratives to retrieve biomedical articles. We compared the performance of pseudo relevance feedback, query expansion based on UMLS synonyms, and query expansion with personalized PageRank. In addition, we investigated the impact of different query formulation on retrieval performance. We also give out future work in this area in the end.
