基于变化生成图的OWL本体协同进化方法研究

Research on the Collaborative Evolution of OWL Ontologies Based on And-or Graph

随着本体规模的不断扩大,由于能力和知识的约束,单个知识工程师已经难以单独对本体进行改进,因此如何实现本体的协同进化成为了一个亟待解决的问题。本文提出了一个能够支持OWL本体协同进化的结构化方法,引入了一种有向的与或图——变化生成图来表示知识工程师的本体改进意图,通过发现变化生成图之间的冲突来找出多个知识工程师本体改进意图之间潜在的矛盾,并通过变化生成图的冲突消解来解决本体改进意图之间的矛盾,使得多个本体改进意图能够并存,从而实现本体协同进化的目标。

With the rapidly ineensement of ontology size, it is very hard/or a knowledge engineer to evolve ontology alone due to the knowledge and ability constraint. So, it is important for knowledge engineers cooperate to evolve the on tology, which we called collaborative evolution. In this paper, we propose a structural OWL ontology cooperative evolution method, and introduce a kind of directed and-or graph（Change Generation Graph）to describe the engineer＇s intention of ontology evolution. The confliction of change generation graphs is also analyzed, and then, this paper propose an algorithm to resolve the confliction, so that engineers＇ intention can coexist, and cooperative evolution is achieved.
