Tutorial on Ontological Engineering: Part 2: Ontology Development, Tools and Languages

摘要

Practical aspects of ontological engineering are discussed in this part. First topic is the methodology of ontology development. Next, ontology representation languages and support tools are discussed as well as ontology alignment and merging which are becoming practically important to cope with distributed development of ontologies. We next discuss several ontologies developed thus far including large-scale knowledge bases such as Cyc, practical domain ontologies such as Enterprise ontology and gene ontology and generic ontologies such as PSL: Process Specification Language and SUO: Standard Upper Ontology. The first topic of ontology applications is the semantic web in which semantic interoperability, metadata and web service ontology are described. e-Learning is also a good application area of ontology in which LOM: Learning Object Metadata and ontology-aware authoring systems are discussed followed by conclusion.
