Semantic manipulation of non- Semantic/natural-language queries

Rapid growth of information has made information access inherently difficult. Semantic Web, with the help of formal Ontologies, has provided an efficient way to represent data which makes it easy to find and organize by creating a mesh of information linked up in machine process-able way. The formal query languages (SPARQL) can exploit the semantics in information access; however formal languages are complex for naive users. On the other hand, keyword search can't benefit from semantics of information. In this paper we present a query interface that performs semantic manipulation of non- semantic natural language-based queries. The proposed query interface semantically manipulates the user query to generate RDF triples to be queried using SPARQL. Proposed system provides the richness of semantics of formal query languages while maintaining query simplicity.
