Abstract
Ontology-based semantic retrieval is a hotspot of current research. In order to achieve fuzzy semantic retrieval for university scientific research information in WWW, this paper proposes an approach using Resource Description Framework (RDF) and fuzzy ontology. First, we apply RDF data model to represent scientific research information. Then, introducing new data type referred as fuzzy linguistic variables to RDF data model, the semantic query expansion in SPARQL query language is constructed by order relation, equivalence relation and inclusion relation between fuzzy concepts defined in linguistic variable ontologies. Examples show that this work facilitates the semantic retrieval through fuzzy concepts for university scientific research management on the Semantic Web.
