Knowledge is an increasingly important asset for organizational competition, and knowledge management becomes the most important issue for an organization. Building knowledge ontology is a good solution to increase knowledge reusability. Ontology explicitly defines concepts and their relationships, which can facilitate user understanding and further analysis.
Based on previous research (Wu, 2006; Chuang, 2006), this research proposes a refined method for the construction of event ontology. The method includes text pre-processing, event ontology construction, and event ontology presentation. The text pre-processing module includes POS tagger, word filter, and term analysis. Based on the concept of sub-event, we can build a 3-level architecture of event ontology that includes sub-events, events, and topics in the event ontology construction module. Event ontology construction module developed in the project provides a friendly editing environment for the user to edit the concepts and attributes of an event that may cover ¡§who,¡¨ ¡§what,¡¨ ¡§where,¡¨ and ¡§what object.¡¨ In the event ontology presentation module, event episode may be illustrated by event frames, flow charts, and Gantt charts.
To verify the feasibility of the proposed method, a prototype system has been built. The Alexander Poison Event was used as an example to demonstrate the value of the prototype system.
