Abstract. Formulating unambiguous queries in the Semantic Web applications is a challenging task for users. This paper presents a new approach in guiding users to generate clear requests based on their common nature of querying for information. The approach known as the “front-end approach” gives users an overview about the system data through a “virtual data component ” which stores the extracted metadata of the data storage sources in the form of an ontology. This approach reduces the ambiguities in users ’ requests at very early stage; and allows the query refinement process to easily to fulfill users’s demands. Furthermore, the approach provide a powerful query engine, called “context-based querying”, that recommends the appropriate query patterns according to the user’s querying context. These features help the user in generating clear query more easier. 1.
