Abstract
It is crucial to enable users of Linked Data to explore RDF-compliant knowledge bases in an intuitive and effective way. It is not reasonable to assume that a regular user posses any knowledge about the SPARQL nor about the ontology of the given knowledge base. This paper presents the Semantic Focused Crawler (SFC) system which features a graph-based querying interface that address this issue. As a result of the use of auto-complete recommendations within the SFC query builder interface, the user benefits from using the ontology irrespectively from the degree of the knowledge about semantic technologies he/she possesses. When compared to several widely-referenced alternative solutions in experiments performed with the use of 2011 QALD workshop questions, the presented system appears as achieving high query results accuracy and low complexity of the query formulation process.
