基于事件链的知识导航模型研究

当前突发公共事件应急管理研究已经成为热点问题.本文从应急管理知识需求出发,研究突发事件对象要素属性关系特点,提出了基于事件链的知识导航模型.该模型由资源模型、知识本体模型、应急处置模型、事件对象模型及事件链模型组成.通过对不同模型间的关系研究,向用户提供方便、快捷、适时的知识导航功能,最后给出应用实例.

Event Chain-Based Knowledge Navigation Model

At present, the emergency management has become a hot issue.From the knowledge need of emergency management, this paper researches the relationship characteristics of unexpected event object elements and proposes the knowledge navigation model based on event chain.This model has five parts:resources model, knowledge ontology model, emergency disposal model, event object model and event chain mo del.Through the studies on relationship between different models, we provide users with convenient, speedy and timely knowledge navigation.At last, an application example is given to present the realization process of the model.
