Agreement Contexts in Formal Concept Analysis
2004This paper describes a technique in which some columns of an n-ary relation are interpreted as defining a situation. For example when considering movies, critics and reviews we talk about the situation when the critic is a particular critic. We then construct a formal context called an agreement context designed to show that which is in common between ...

Basic Level of Concepts in Formal Concept Analysis
2012The paper presents a preliminary study on basic level of concepts in the framework of formal concept analysis (FCA). The basic level of concepts is an important phenomenon studied in the psychology of concepts. We argue that this phenomenon may be utilized in FCA for selecting important concepts.

Relational Reasoning in Formal Concept Analysis
2007 IEEE International Fuzzy Systems Conference, 2007We show that a logical formalism of binary relations can serve as a tool for specification and verification of a variety of tasks in the formal concept analysis.

Formal concept analysis on fuzzy sets
2013 Joint IFSA World Congress and NAFIPS Annual Meeting (IFSA/NAFIPS), 2013Formal Concept Analysis (FCA) is a theory on relations between sets, and has already been extended to a theory on fuzzy relations between (crisp) sets. In this note, in the case that (L; &) is a commutative and divisible complete residuated lattice, FCA is extended further to a theory on fuzzy relations between fuzzy sets.

Formal concept analysis in intuitionistic fuzzy formal context
2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery, 2010This paper mainly studies the formal concept analysis in an intuitionistic fuzzy formal context. The primitive notions in concept lattice theory are extended to the intuitionistic fuzzy environment. According to this view, the notion of crisp-intuitionistic fuzzy concept is proposed which originates from an defined extent operator and an intent ...

Formal concept analysis (FCA) is a mathematical theory about concepts and concept hierarchies. Based on lattice theory, it allows to derive concept hierarchies from datasets. In this survey, we recall the basic notions of FCA, including its relationship to folksonomies. The survey is concluded by a list of FCA based knowledge engineering solutions.

AFS Formal Concept and AFS Fuzzy Formal Concept Analysis
2009In this chapter, based on the original idea of Wille of formal concept analysis and the AFS (Axiomatic Fuzzy Set) theory, we presents a rigorous mathematical treatment of fuzzy formal concept analysis referred to as an AFS Formal Concept Analysis (AFSFCA).

Formal Concept Analysis (FCA) is a multi-disciplinary field built on the solid foundation of lattice and order theory. Besides this, FCA is strongly rooted in philosophical aspects of the mathematical formalization of concept and concept hierarchy. Since its emergence in the 1980s the field has developed into a constantly growing research area in its ...
