Enhancing search results of concept annotated documents

Concepts describing documents can offer a way for semantically grounding these documents. The goal of the work presented in this paper is to investigate making use of such concepts and the existence of an ontology in order to enhance search results in a known domain. So in this work we experiment with various techniques to achieve this goal. Experiments presented in this paper show that relying only on concept indexing and matching leads to degraded search results. This paper proposes an integrated approach based on augmenting a classical search technique with a concept based one which utilizes semantic information to improve the search results. A detailed discussion of the reported experimental results is also presented.
