Abstract/Summary:
Knowledge management enables organisation to gain strategic economic competitiveness by managing its intellectual assets. In recent years, Semantic Web technology has been used to discovers, capture, store, disseminate, share and reuse knowledge. Since most of organisational knowledge in the form of unstructured text documents, ontology learning methodologies are used to extract and model the concepts and its relationship, and present it as ontologies.;However, most of ontology learning approaches used in knowledge management initiatives are centralised and developed by a small group of domain expert and knowledge engineers. The end users of domain ontology based application are neglected in building ontology. This isolated ontology development has hindered the mass adoption of semantic technology in knowledge management communities. The complexity in ontology learning procedures and techniques is another barrier that has hindered user participation. User involvement in ontology building is important as they are the originators and benefactors of domain knowledge. In order to allow mass adoption and participation in ontology building, users need to be empowered with simpler tools and techniques.;In this research, a decentralised user based hybrid ontology learning framework is introduced which combine lexico-syntactic techniques and XML based techniques wit h the use of an integrated ontology development environment (IODE). The lexico-syntactic method utilises the subject-predicate-object pattern. The XML technique is used to provide a transition model to structure the extracted semantics to support smoother ontologies translation. The use of IODE is to generate the ontologies using a predefined built in ontology that converts XML to OWL translation.
