Abstract: Event ontology design pattern (EODP) is a solution to facilitate event ontology development, and to help reducing arbitrariness design and avoiding the same mistakes in the modeling process. This paper firstly proposes a general event model structure for the representation of general event information on Web, without making assumptions about the domain-specific vocabularies used. And then, this paper presents the concept of EODP and the development method of EODP, by which an environment pollution event ontology pattern is proposed based on shared  vocabulary. At last, this paper discusses the formalization of the environment pollution event ontology pattern by    using the description logic, which verifies the effectiveness and concept-consistency while modeling domain ontology by using the event ontology pattern.

Key words: environmental pollution emergency, event ontology pattern, description logic

摘要： 事件本体设计模式（event ontology design pattern，EODP）是加快事件本体构建，避免设计歧义以及在建模过程中重复出现相同错误的一种解决方案。提出了一种通用的事件模型结构，该模型结构可以在没有特定领域词汇的情况下表示Web文本中最一般性的事件信息。在此基础上，提出了事件本体模式概念和事件本体模式的提取方法，并利用该方法建立了基于共享词汇的环境污染突发事件本体模式。最后，利用描述逻辑对环境污染突发事件本体模式进行形式化，验证了使用事件本体模式实现领域事件本体建模的有效性和概念一致性。
