Query expansion using Wikidata attributes’ values

One of the well known techniques that are used to increase the relevancy of user queries is query reformulation through the expansion of queries. Also, Linked data are being used in various fields and available for different domains. This paper aimed at improving Information Retrieval results using Linked data from Wikipedia in general and Wikidata in particular to expand the queries with attributes‟ values. The experiments that we have done, using Medline collection and Indri search engine to compare our suggested approach with baseline, lead to improvements in precision at different ranks.
