The Most Outstanding Ontologies

Abstract

This chapter is devoted to presenting the most outstanding ontologies. In this survey, we have considered different types of ontologies: knowledge representation ontologies (Section 2.1), top-level ontologies (Section 2.2), linguistic ontologies (Section 2.3) and domain ontologies (Section 2.4). In this last section, we will deal with ontologies from the following domains: e-commerce, medicine, engineering, enterprise, chemistry, and knowledge management.
