Abstract

During the ontology conceptualization activity, developers usually generate preliminary models of the ontology in the form of diagrams. Such models drive the ontology implementation activity, where the models are encoded using an implementation language, typically by means of ontology editors.

The goal of this demo is to take advantage of the developed ontology conceptualizations in order to accelerate the ontology implementation activity.

For doing so we present Chowlk, a converter to transform digital UML-based ontology diagrams into OWL. This system aims at supporting users in the generation of the first versions of ontologies by reusing the ontology conceptualization output.

Conclusions and future work

  1. The Chowlk converter that facilitates the ontology development process by leveraging the ontology conceptualization diagrams to transform them into OWL
  2. Next steps involve the announcement and promotion of the system to get feedback from users
  3. Development of a plugin for diagrams.net in order to embed the ontology generation feature into the diagramming tool
