Abstract
Existing methodologies for ontology engineering have reached a mature state over the years. They started from the pure adoption of software engineering principles and practices and are now at a point of defining specific glossaries, methods and guidelines for ontology engineering inherited from them.
|
However, during the kick-off phase oft the project Corporate Semantic Web we found business gaps between current ontology engineering approaches and the knowledge management and information systems reality in companies. Thus, we designed an innovative methodology for ontology lifecycles in corporate settings – COLM. COLM addresses scenarios with a strong need of agile and cost-effective evolution of ontology prototypes and makes a significant disctinction between an expert-oriented engineering phase and ontology usage. The methodology is currently in use at the company Ontonym which provides web services for semantic query expansion and semantic matching in the recruitment domain. Ontologies are the main asset of Ontonym and, thus, an effective ontology modeling methodology is essential.
