Ontologies are a key support to provide a shared understanding of knowledge domains. Their flexibility and usefulness is witnessed in a variety of scenarios, from knowledge-based retrieval to projects like the Semantic Web. The possibility to express semantic information gave birth to a new class of query languages specifically designed. We will give an overview of one of such languages called SPARQL. SPARQL is the W3C standard to query data represented in RDF, another W3C standard. By using examples, we illustrate the structure of a SPARQL query. Then, we give an overview of popular ontology management tools.

Abstract
Ontologies are a key support to provide a shared understanding of knowledge domains. Their flexibility and usefulness is witnessed in a variety of scenarios, from knowledge-based retrieval to projects like the Semantic Web. The possibility to express semantic information gave birth to a new class of query languages specifically designed. We will give an overview of one of such languages called SPARQL. SPARQL is the W3C standard to query data represented in RDF, another W3C standard. By using examples, we illustrate the structure of a SPARQL query. Then, we give an overview of popular ontology management tools.File in questo prodotto:
