An Investigation of the Effectiveness of Concept-based Approach in Medical Information Retrieval
نویسندگان
چکیده
In our participation in the CLEF 2014 eHealth task 3a, we investigate the effectiveness of concept-based retrieval techniques on medical IR. Concepts are determined using the existing resources and tools: UMLS Metathesaurus and MetaMap. We tested several methods based on concepts. Although some of these methods lead to slight improvements in retrieval effectiveness over a traditional bag-of-words method, the impact of the rich domain ressource is lower than we expected. So the whole question on whether and how such a resource can help improve medical IR effectiveness remains open. In this report, we describe the methods tested as well as their results.
