形式概念分析(FCA)是一种基于概念和概念层次的形式化的数学理论。它已成功地应用于数据挖掘、软件工程、知识工程等计算机科学领域,以及医学、心理学、语言学、生态学等许多领域。例如,它已经被用于本体的设计、映射和细化。在本文中,我们通过分析分类法(对象和/或属性)对结果概念格的影响,展示了FCA如何从给定的领域本体中受益。我们将主要集中在使用分类法以概念和规则的形式提取广义模式(即,当使用给定领域本体的元素时,从数据中生成的知识),并改进通过这些模式的导航。为此,我们分析了三种推广情况,并说明了它们对推广模式集大小的影响。文中还讨论了对象和属性同时泛化的不同场景

英文摘要:
  Formal Concept Analysis (FCA) is a mathematical theory based on the formalization of the notions of concept and concept hierarchies. It has been successfully applied to several Computer Science fields such as data mining,software engineering, and knowledge engineering, and in many domains like medicine, psychology, linguistics and ecology. For instance, it has been exploited for the design, mapping and refinement of ontologies. In this paper, we show how FCA can benefit from a given domain ontology by analyzing the impact of a taxonomy (on objects and/or attributes) on the resulting concept lattice. We willmainly concentrate on the usage of a taxonomy to extract generalized patterns (i.e., knowledge generated from data when elements of a given domain ontology are used) in the form of concepts and rules, and improve navigation through these patterns. To that end, we analyze three generalization cases and show their impact on the size of the generalized pattern set. Different scenarios of simultaneous generalizations on both objects and attributes are also discussed
