چکیده

Formal Concept Analysis -also called "Galois Lattices"is an algebraic model based on propositional calculus that is used for symbolic knowledge exploration from a formal context. The aim of this paper is to design the theoretical models required for the extension of Formal Concept Analysis to first-order logic so as to improve both the expression power as a knowledge mining tool upon first order contexts, and the relevance of its results. Our contribution consists in: i) a synthesis of the basic notions of FCA, ii) the design of the Cube Model dedicated to the conjunctions of literals, iii) the design of a complete first-order logic formal concept analysis of first-order contexts. The approach is described from the theoretical point of view, implementations in logic programming and applications are also briefly presented.

A Note on Computing the Crisp Order Context of a Fuzzy Formal Context for Knowledge Reduction

Fuzzy Formal Concept Analysis (FCA) is a mathematical tool for the effective representation of imprecise and vague knowledge. However, with a large number of formal concepts from a fuzzy context, the task of knowledge representation becomes complex. Hence, knowledge reduction is an important issue in FCA with a fuzzy setting. The purpose of this current study is to address this issue by proposi...

Formal-comparative analysis of the spatial organization of student residence halls based on their spatial threshold patterns

Functional quality of the student residence halls has a great deal of importance due to their collective nature and the fact that they are considered as housing units, identifying and defining the role of intermediary spaces on the spatial organization and and spatial consociation of student residence halls which is a compound system of masses and spatial borderlines can bring order to its syst...

Conceptual Analysis of fuzzy data using FCA

In order to analyze vague data set of uncertainty information, Fuzzy Formal Concept Analysis(FFCA) incorporates fuzzy set theory into Formal Concept Analysis(FCA). It extracts useful information with a unit of fuzzy concept from given fuzzy formal context with a confidence threshold. Then it constructs fuzzy lattice by order relations between the fuzzy concepts. In this paper, we introduce basi...

Concepts and Types - An Application to Formal Language Theory

We investigate how formal concept analysis can be applied in a type-theoretic context, namely the context of λ-terms typed à la Curry. We first show some general results, which reveal that concept lattices generally respect and reflect the type structure of terms. Then, we show an application of the results in formal language theory, where we vastly generalize existing approaches of capturing t...

Concept lattices of fuzzy contexts: Formal concept analysis vs. rough set theory

This paper presents a comparative study of concept lattices of fuzzy contexts based on formal concept analysis and rough set theory. It is known that every complete fuzzy lattice can be represented as the concept lattice of a fuzzy context based on formal concept analysis [R. Bělohlávek, Concept lattices and order in fuzzy logic, Ann. Pure Appl. Logic 128 (2004) 277–298]. This paper shows that ...
