Abstract:

We introduce two heterogeneous query expansion techniques, and a combined system to the TREC 2012 Medical Track. Our methods are based on external resources that provide expansion concepts related to the query terms, by means of the PageRank algorithm, and simple rules based on UMLS Semantic Types. In this paper we show that our systems are able to reach competitive performances at both the TREC-2011 and TREC-2012 tasks.
