dc.description.abstractWhile keyword based techniques continue to be the most popular option for information services, the limitations inherent in keywords routinely generate unsatisfactory results. As a promising alternative, ontology based solutions have been proposed to provide effective information services by exploiting ontologies for representing and organizing information. This thesis addresses the key issues in adopting ontology based solutions by presenting a collection of methods and systems for ontology building, ontology exploitation, and ontology analysis. In any ontology based solution, ontologies firstly have to be created for representing and organizing information. However,ontology building is well known to be a tedious process. Manually acquiring knowledge for building domain ontologies requires much time and resources. To ease the efforts of building ontologies, we develop a system called Concept-Relation-Concept Tuple based Ontology Learning (CRCTOL) for automatically learning ontologies from domain specific text documents. By using a full text parsing technique and incorporating both statistical and lexico-syntactic methods, the ontologies learned by our system are more concise and contain a richer semantics in terms of the range and number of semantic relations compared with alternative systems.en_US
