The development of robust and widely used ontologies is an increasingly important tool in the fight against information overload. The publishing and sharing of explicit explanations for a wide variety of conceptualizations, in a machine readable format, has the power to both improve information retrieval and identify new knowledge. This new book provides an accessible introduction to
- the concept and definition of ontology and why it is increasingly important to the information professional;
- ontologies and the Semantic Web;
- existing ontologies, such as SKOS, OWL, FOAF, schema.org, and the DBpedia Ontology;
- adopting and building ontologies, showing how to avoid repetition of work and how to build a simple ontology with Protégé;
- interrogating Semantic Web ontologies; and
- the future of ontologies and the role of the information professional in their development and use.
