面向事件的本体研究

Research on Event-oriented Ontology Model

世界是物质的,物质的世界是运动的,运动是绝对的,静止是相对的。事件作为人类知识的单元,反映了事物的运动,受到了学术界多领域专家的高度重视。在研究面向事件的知识表示的基础上,给出了事件定义及其六元组的形式化表示,并提出了事件本体模型;最后,以基于事件本体的篇章理解为例,简要说明了篇章与句子的事件网络表示、生成及其应用。与传统本体相比,事件本体以更高粒度的事件作为知识表示单元,更符合客观实际,更便于计算机模拟大脑工作。

Event-oriented knowledge representation method is reasonable according to the philosophical viewpoints that the world is of material, material is of movement, movement is absolute and static is relative. Nowadays, the academic community has paid more and more attention to event that is the unit of knowledge. By studying of the Event-oriented Knowledge representation, the definition of event was given and the representation of event in a 6-tuple formalized structure was presented. Then, an event ontology model was proposed. Taking text understanding as an application do- main, the representation, building and application of the event network of texts and sentences were briefly introduced. In comparison with the conventional method, event ontology model represents knowledge with a higher granularity, meanwhile, it＇ ll be much more suitable for computers to simulate human brain.
