Characterizing One-Sided Formal Concept Analysis by Multi-Adjoint Concept Lattices

open access: yesMathematics, 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 ...

Method of Updating Formal Concept Under Covering Multi-granularity [PDF]

open access: yesJisuanji kexue, 2023
Multi-granularity formal concept analysis is an important tool for data mining and knowledge discovery.This paper studies the methods of coarsening and refining formal concepts under multi-granularity.Firstly,it is proved that the existing concept ...

Formal Concepts and Residuation on Multilattices

open access: yesFundamenta Informaticae, 2023
Multilattices are generalisations of lattices introduced by Mihail Benado. He replaced the existence of unique lower (resp. upper) bound by the existence of maximal lower (resp. minimal upper) bound(s). A multilattice will be called pure if it is not a lattice. Multilattices could be endowed with a residuation, and therefore used as set of truth-values

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)

On inference rules in decision formal contexts [PDF]

open access: yesInternational 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.

Attribute Reduction in Soft Contexts Based on Soft Sets and Its Application to Formal Contexts

open access: yesMathematics, 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 ...

XAI USING FORMAL CONCEPT LATTICE FOR IMAGE DATA [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2023
A Formal concept lattice can be used to generate explanations from a black box model. This novel approach has been applied and proven for tabular data. It has also been compared to popular techniques in XAI.

Concept similarity in formal concept analysis

open access: yesJournal 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.

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).
