Popis:	This paper presents a semantic approach based on DBpedia and WordNet to extract the candidate terms for query expansion. We divided DBpedia features into: general features and specific features that are available depending on the domain of the resource. We evaluated our approach using 44 queries from TREC AP88-90, and discovered that the results are improved when using the hybrid approach that combines WordNet and DBpedia, versus using only WordNet for short and long queries. The comparison of our approach with literature technique that used DBpedia for query expansion showed an improvement in P@20 for both short and long queries.
