Developing Using Ontologies for the Semantic Web: An Inspirational and a Synthetic Approach to Ontological Engineering Utilizing WordNet in Information Retrieval

摘要

Ontological engineering is explored via the inspirational approach of creating ontologies through oneu2019s own imagination and the synthetic approach of developing ontologies through the synthesis of existing ones. The inspirational approach is implemented in two toolkits, one with minimal constructs and guidance and the other with constructs such a functional contexts and granularity. The synthetic approach is implemented in a toolkit that makes use of WordNet to generate semantically similar concepts across source ontologies, so as to support semi-automated merging. Lastly, an ontology-based information retrieval system is developed as a characteristic example of the use of ontologies in common applications.
