面向语义Web的Expressive格值描述逻辑

Very Expressive Fuzzy Description Logics over Lattices for the Semantic Web (in English)

摘要: 提出了一种基于可信度格的Expressive模糊描述逻辑框架,对描述逻辑SROIQ(D)进行了模糊化扩充,建立了一种面向语义Web的基于格的模糊描述逻辑L-SROIQ(D),给出了L-SROIQ(D)的语法、语义和逻辑性质,以及建立了一个线序格下的将模糊描述逻辑L-SROIQ(D)转换为经典描述逻辑SROIQ(D)的推理算法,从而证明了线序格下L-SROIQ(D)的可满足性推理是可判定的。

Abstract: In this paper we present a very expressive fuzzy description logic framework, L-SROIQ(D), based on certainty lattices, which is a fuzzy extension of the description logic SROIQ(D) (theoretical basis of the ontology language OWL 2). Some logical properties of L-SROIQ(D) are researched and the decidability of L-SROIQ(D) is proved in case of linearly ordered lattices.
