顶层本体比较及评估

Comparison & Evaluation of Upper Ontologies

元本体、顶层本体、领域本体、任务本体和应用本体构成了本体的主要类型,其中顶层本体表达常识性基本概念,领域本体的设计者通常基于顶层本体已定义的概念及概念之间的关系来构建领域的概念,从而更好地实现本体与本体之间的重用与集成。本文对SUMO、OpenCyc、DOLCE三个顶层本体的结构体系进行了分析,结合开放许可度、结构化、成熟度3个评价指标,比较这3个现有的较为完备的顶层本体,以帮助本体设计者选择具备发展前景、在国际范围应用广泛的顶层本体。

Ontology is made up of meta ontology, upper ontology, domain ontology, task ontology and application ontology. Among them, the upper ontology is used to express the basic concept of common knowledge. The designers of domain ontology usually construct the domain concepts based on the defined concepts and relations among concepts of upper ontology in order to reuse and integrate ontologies. This paper gives an analysis of the construction system of SUMO, OpenCyc and DOLCE and makes a comparison of the 3 relatively mature upper ontologies in order to help designers choose well-developed and widely used ontology.
