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.

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 ...

Monadic Formal Concept Analysis
2014Formal Concept Analysis (FCA) as inherently relational can be formalized and generalized by using categorical constructions. This provides a categorical view of the relation between “object” and “attributes”, which can be further extended to a more generalized view on relations as morphisms in Kleisli categories of suitable monads. Structure of sets of

Identifying traits with formal concept analysis
Proceedings of the 20th IEEE/ACM International Conference on Automated Software Engineering, 2005Traits are basically mixins or interfaces but with method bodies. In languages that support traits, classes are composed out of traits. There are two main advantages with traits. Firstly, decomposing existing classes into traits from which they can be recomposed improves the factoring of hierarchies. Secondly it increases the library reuse potential by

Data granulation and formal concept analysis
IEEE Annual Meeting of the Fuzzy Information, 2004. Processing NAFIPS '04., 2004Understanding the associations among the data items of a given dataset plays a significant role in data mining. One of the well-known methods that deliver the associations among data items is Formal Concept Analysis (FCA) that is able to represent the associations among data items as a lattice.

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 Context Analysis is a mathematical theory that enables us to find concepts from a given set of objects, a set of attributes and a relation on them. There is a hierarchy of such concepts, from which a complete lattice can be made. In this paper we present a generalization of these ideas using fuzzy subsets and fuzzy implications defined from ...
