Sammendrag
A large number of ontologies, covering various domains, have been published and are already available for practical adaption and use. They are becoming more meaningful mechanism, as a means to reference and build software systems. Especially in the context of exploiting and deriving reusable knowledge from existing ontologies, for the purpose of specifying development of software. Nonetheless, to many, the nature and applications of ontologies are unfamiliar. In addition to this, acquiring and adopting to reusable design from existing ontologies is not a simple task.
Since documentation is an essential part of use and reuse of existing ontologies, but is still not properly addressed. To compromise this, the work in this thesis have been designing and implementing a tool support, that facilitate in design of ontologies using a graphical symbolism. This have been approached based on studying the reuse mechanisms of ontologies. Furthermore, investigating in the closely related coupling between the building blocks of ontologies and objects, to represent ontology design as object-models, by means of the Unified Modeling Language (UML). Besides visual editing, the tool supports browsing and exploration of specifications from a source ontology, presented in a human readable manner. This way, it helps the users to see complex, ontological principles and definitions, that is otherwise difficult to identify in the underlying ontology.
The result is a prototype tool that can go beyond pure modeling tool capabilities, by integrating ontology-based data and modeling environment, in addition to, providing look-up functionality for keyword search. Furthermore, the usefulness of the tool is argued by conducting a usability test, and usability measurements of the tool have been evaluated by user feedbacks.
