实例检查被认为是从描述逻辑(DL)本体中检索数据的核心工具。在本文中,我们提出了一个修改的最具体的概念(MSC)的方法DL,它转换为包容问题的实例检查。这种修改后的方法可以生成足够具体的小概念来回答给定的查询,并允许推理只探索ABox数据的一个子集,以实现效率。实验表明,我们提出的方法的有效性方面的概念大小减少和推理效率的提高。
Instance checking is considered a central tool for data retrieval from description logic (DL) ontologies. In this paper, we propose a revised most specific concept (MSC) method for DL, which converts instance checking into subsumption problems. This revised method can generate small concepts that are specific-enough to answer a given query, and allow reasoning to explore only a subset of the ABox data to achieve efficiency. Experiments show effectiveness of our proposed method in terms of concept size reduction and the improvement in reasoning efficiency.
