CRP Henri Tudor at TREC 2014: Combining Search Results for Clinical Decision Support

This paper presents the first participation of the Luxembourgish Public Research Center Henri Tudor in the TREC 2014 Clinical Decision Support (CDS) Track. At the Resource Centre for Healthcare Technologies (SANTEC) department, we focus our research activities on healthcare technologies. Our mission consists primarily in improving healthcare by developing methods, tools, services and solutions that can be applied by healthcare professionals, patients and citizens on a daily basis. In this research work, we present an approach to combining search results using data fusion techniques. The focus of the 2014 Clinical Decision Support Track was the retrieval of relevant biomedical articles for answering generic clinical questions about medical records. Each question consists of a case report and one of three generic clinical question types, such as “What is the patient’s diagnosis?”. Retrieved articles are judged relevant if they provide information of the specified type that is relevant to the given case. The remainder of this report is organized as follows. Section 2 gives a brief description about the CDS Task. Section 3 describes our methodology for combining search results. Our submitted runs and the official results of TREC CDS Track are described in Section 4. Finally, Section 5 draws our conclusions and outlining directions for future work.
