Abstract: Recent advances in the Semantic Web research community actuated the experimentation with a variety of approaches concerning the retrieval of Semantic Web Documents (SWDs). Most approaches require that queries are formed in a structured and formal way. Given the inability of the majority of web users to express formal queries, this paper proposes an approach to SWDs| retrieval, aiming to support users to place queries, requiring no knowledge and skills for expressing these queries in a formal language. The paper discusses specific issues that are considered towards the retrieval of SWDs using free-form queries and presents an evaluated two-step approach.

Keywords: semantic search; semantic web documents; SWD; query ontology; semantic retrieval; formal queries; information retrieval; document retrieval; free-form queries.
