Conceptual Coverage Driven by Essential Concepts: A Formal Concept Analysis Approach
Mathematics, 2021 Formal concept analysis (FCA) is a mathematical theory that is typically used as a knowledge representation method. The approach starts with an input binary relation specifying a set of objects and attributes, finds the natural groupings (formal concepts)

Concept similarity in formal concept analysis
Journal of Mathematical and Computational Science, 2022 The identification of syntactically different concepts that are semantically similar, also referred to as Similarity Reasoning, is fundamental in several research areas such as Artificial Intelligence, Software Engineer- ing, Cognitive Science and, in particular, in Semantic Web.

Attribute Reduction in Soft Contexts Based on Soft Sets and Its Application to Formal Contexts
Mathematics, 2020 We introduce the notion of the reduct of soft contexts, which is a special notion of a consistent set for soft contexts. Then, we study its properties and show that this notion is well explained by the two classes, 1 0 and 2 0 , of ...

An Order-Theoretic Study on Formal Concept Analysis
Axioms, 2023 This paper employs an order-theoretic framework to explore the intricacies of formal concepts. Initially, we establish a natural correspondence among formal contexts, preorders, and the resulting partially ordered sets (posets).

Electronic Notes in Discrete Mathematics, 1999 Formal concept analysis (FCA) [71] is a mathematical theory for concepts and concept hierarchies that reflects an understanding of “concept” which is first mentioned explicitly in the Logic of Port Royal [2] in 1668 and has been established in the German standard ‘DIN 2330 – Concepts and terms; general principles’ [19].

Study of Implication Representation Based on Decision Implication
Jisuanji kexue yu tansuo, 2021 Formal concept analysis can use concept lattice and (attribute) implication to visualize and represent knowledge. Decision implication is a special implication, and the study of decision implication is to establish and study one or more closed subsystems

Distances Between Formal Concept Analysis Structures [PDF]
Transactions on Graph Data and KnowledgeIn this paper, we study the notion of distance between the most important structures of formal concept analysis: formal contexts, concept lattices, and implication bases.
