摘要

描述逻辑的模糊扩展通常基于精确隶属函数,它将特定的实数赋给一个元素或宇宙的一个子集。在某些情况下,我们可能只能识别大约适当的隶属度,使用精确的隶属度函数变得不合适。在区间值模糊集的基础上,提出了描述逻辑EL++的广义模糊扩展Gf-EL++。本文给出了使用“区间值模糊包容”扩展概念包容的gf - el++的语法和语义。我们同样提出了一种易于处理的gf - el++的包容算法。

A generalized fuzzy extension of EL++
Fuzzy extensions of Description Logics are generally based on precise membership functions which assign a particular real number to an element or a subset of the universe. In some cases where we may only be able to identify approximately appropriate membership degrees the use of precise membership functions become unsuitable. In this paper we propose a generalized fuzzy extension of the description logic EL++, named Gf-EL++, based on interval-valued fuzzy sets. We present the syntax and the semantics of Gf-EL++ which uses an extension of concept subsumption with “interval-valued fuzzy subsumption”. We equally propose a tractable subsumption algorithm for Gf-EL++.
