1·Based on this thought, we propose an IDS alert correlation model based on description logics.

在此思想基础上，进一步提出了基于描述逻辑的IDS告警关联模型。

2·These semantic - based systems use description logics, concept contraction and concept abduction to compute the matchmaking degree.

基于语义的系统用描述逻辑、概念收缩法和概念试推法，计算语义匹配度大小。

3·Description Logics (DLs) is a decidable subset of first-order predication logic which possesses powerful function of knowledge expressing and reasoning.

描述逻辑是一阶谓词逻辑的可判定子集，具备强大的知识表示和推理功能。

4·On the research of ontology description logics, semantic extraction and fuzzy geometric features, a new simulation algorithm including four steps is proposed.

通过比较提取骨架方式得到的实验结果和样本两者的模糊几何特征，可调整算法参数，完善仿真。

5·Description logics systems offer a set of typical inference services, such as concept's classification, satisfiability and realization, knowledge base consistency checking.

描述逻辑系统可以提供一些典型的推理服务，例如，概念分类，概念的可满足性及概念的实现，知识的一致性检测等一系列的推理服务。
