An Order-Theoretic Study on Formal Concept Analysis

open access: yesAxioms, 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).

Conceptual Coverage Driven by Essential Concepts: A Formal Concept Analysis Approach

open access: yesMathematics, 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)

Study of Implication Representation Based on Decision Implication

open access: yesJisuanji 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

Four-Fold Formal Concept Analysis Based on Complete Idempotent Semifields

open access: yesMathematics, 2021
Formal Concept Analysis (FCA) is a well-known supervised boolean data-mining technique rooted in Lattice and Order Theory, that has several extensions to, e.g., fuzzy and idempotent semirings.
