Continuous Domains in Formal Concept Analysis [PDF]
Fundamenta Informaticae, 2021 Formal Concept Analysis (FCA) has been proven to be an effective method of restructuring complete lattices and various algebraic domains. In this paper, the notion of contractive mappings over formal contexts is proposed, which can be viewed as a generalization of interior operators on sets into the framework of FCA.

Meta-Modelling in Formal Concept Analysis
CoRRFormal Concept Analysis starts from a very basic data structure comprising objects and their attributes. Sometimes, however, it is beneficial to also define attributes of attributes, viz., meta-attributes. In this paper, we use Triadic Formal Concept Analysis, a triadic approach to Formal Concept Analysis, to develop a framework for this kind of meta ...

Characterizing One-Sided Formal Concept Analysis by Multi-Adjoint Concept Lattices
Mathematics, 2022 Managing and extracting information from databases is one of the main goals in several fields, as in Formal Concept Analysis (FCA). One-sided concept lattices and multi-adjoint concept lattices are two frameworks in FCA that have been developed in ...

On inference rules in decision formal contexts [PDF]
International Journal of Computational Intelligence Systems, 2015 Rule acquisition is one of the main purposes in the analysis of decision formal contexts. In general, the number of implications in a decision formal context is an exponential increase to the scale of the database.

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).

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
