The Queries Expansion on Biomedical Terminologies: Toward a Comparison of Knowledge Representation Artifacts for Information Retrieval

We live in a period in which there is a remarkable availability of information. However, we still demand improvements in methods for information retrieval, including those applied to scientific papers. We focus here on artifacts of knowledge representation as a way to provide mechanisms for query expansion, as part of an ongoing project that aims to compare the effectiveness of biomedical terminologies regarding information retrieval, we present a research framework and the partial results obtained thus far.
