摘要： 为使本体能够方便地表达、处理与时间相关的信息，将有效时间概念引入本体模型，介绍有时态本体模型定义及相关定理，在此基础上，实现有时态本体管理原型系统，并将该原型系统应用于存在时态冲突的信息集成系统中进行实验。实验结果证明了将本体用有效时间进行扩展，从而形成有时态本体模型，并对其进行存储管理的必要性，同时也显示了该原型系统对时态查询的支持能力。

Abstract: In order to express and deal with the time-related information using ontology, this paper introduces valid time into ontology and presents a kind of Temporal Ontology Model(TOM). It provides the definition and related theorems of TOM. On this basis, it implements a prototype of Temporal Ontology Management System(TOMS) and applies it to information integration systems which exists temporal conflicts. Experimental results show the necessity of temporal extensions and management to ontologies. It also demonstrates that TOMS has ability to support temporal queries.
Key words:
temporal ontology,
valid time,
