摘　　要：通过分析关于事件研究的成果,提出事件网络模型.事件网络是一种新的知识表达模型,具有事件单元和概念单元,可以描述现实世界的运动与变化.事件单元由多个角色的概念单元通过语义关系组合而成;每个角色的概念单元的属性间存在偏序关系,通过偏序关系可生成概念层次;每个概念层次都可用资源概念格来表达.因此,多资源概念格可形式化事件网络模型.事件单元以事件个体和事件类来体现,概念单元以实体个体和实体类来体现,因此,可以事件网络为核,通过映射规则,将事件网络映射为事件本体.事件本体是在基于实体类的传统概念本体上,增加事件类而扩展的新型本体.利用事件本体实现的事件知识检索系统,验证了事件网络模型的可行性和有效性.According to the result analysis of events,an event network model is proposed.The event network is a new know ledge representation model with the event unit and concept unit,which can describe the movements and changes in the real world.An event unit is made up of a number of concept role units through semantic relations.Because of partial order between the properties of the concept unit of each role,the concept hierarchies can be generated.Every concept hierarchy can be represented by a resource concept lattice.Therefore,the event network can be formalized by employing multi resource concept lattices.Because the event unit is embodied by event individual and event class,and the concept unit is embodied by entity individual and entity class,the event network as a nucleus will be mapped to event ontology through the mapping rules.The event ontology with event class added is a new type of ontology which is extended on the basis of the traditional concept ontology with entity class.A retrieval system for event knowledge is implemented by employing event ontology.The experiments show that the event network model is feasible and effective.
