Abstract
The Web of Data proposes to publish and connect data by applying the semantic web technologies for the representation of knowledge and data and the definition of queries. The success of the Web of Data requires that both humans and machines are able to extract information from such semantic repositories. For this purpose, query interfaces for humans must make the interaction with the repository as transparent as possible. In this work, we present a generic method for querying semantic repositories based on processing and recognizing the keywords input by the users as entities of the ontology used in the description of the data. A SPARQL query is automatically derived from the query graph extracted from the list of keywords. We also describe the application of the method to three different semantic repositories from different domains.
