Expanded Abstract for Protégé Workshop Jul 6 - 9 , 2004 Enterprise Vocabulary Development in Protege / OWL : Workflow and Concept History Requirements

چکیده
The National Cancer Institute has developed the NCI Thesaurus, a biomedical vocabulary that provides consistent, unambiguous codes and definitions for concepts used in cancer research. It currently has about 34,000 concepts, in 20 hierarchies. A lexical component provides human usable definition and other information. Description logic is used to ensure complete, consistent and non-redundant definitions in the formal sense. NCI Thesaurus enables retrieval of information across a wide range of domains related to cancer research, with one goal being facilitating translational research. This vocabulary was originally built using Ontylog, a description logic developed explicitly for building large complex terminologies by Apelon, and implemented in the Apelon Terminology Development Environment (TDE). We have converted the Ontylog version of NCI Thesaurus to OWL, and are beginning to test the features of Protege OWL in a multi-user environment with a database backend to determine whether it could be used to support the operational needs of NCI Thesaurus development and maintenance.

The Protege OWL Experience
Protégé is one of the most widely used development platforms for ontology-based systems. We report on our experiences with the development of OWL support for Protégé, and on the experiences of our user community with OWL. While the overall feedback from the community has been positive, our experience suggests that there are considerable gaps between the user requirements, the expressivity of OW...
متن کاملCase Study: Using Protege to Convert the Travel Ontology to UML and OWL
Our goal was to evaluate the import/export capabilities of Protégé between various ontology file formats. As a starting point, we chose the Travel ontology used for the Protégé experiment from the previous EON workshop. We exported this into UML, from where we could import most of the ontology into the mainstream software development tool Poseidon. Furthermore, we exported the ontology into OWL...
متن کاملDesigning User interfaces to Minimise Common Errors in Ontology Development: The CO-ODE and HyOntUse Projects
Understanding and using OWL can be difficult. Until recently, the difficulty was made, if anything, greater by user interfaces which were designed more to demonstrate OWL than to fit users requirements. The new interfaces being developed in the Protégé-OWL/CO-ODE/HyOntUse projects are based, to a large extent, on experience in tutorials, workshops, and practical development with users. They are...
متن کاملApplying OWL Ontology to Zachman Framework for Requirement Analysis
When the requirements of stakeholders are identified for the system development, the requirements collected should be formalized for their analysis and use. Zachman Framework is an enterprise architecture framework that provides a formal and highly structured way of viewing and defining an enterprise; it can provide a systematic way to formalize the requirements. This paper proposes an OWL onto...
متن کاملDescription Ontology of studies at universities or Developing ontologies with legal documents as primary knowledge sources
Domains that could be especially interesting and challenging for ontology development are certainly those described by laws and formal documents. Namely, a term "loophole in the law" is well known. Examples of such a domain are also studies at Croatian universities, as well as ontology of one part of Croatian Family Legislation Act that covers motherhood and parenthood terms. Studies at univers...
