Direct Factorization by Similarity of Fuzzy Concept Lattices by Factorization of Input Data
The paper presents additional results on factorization by similarity of fuzzy concept lattices. A fuzzy concept lattice is a hierarchically ordered collection of clusters extracted...

Graded LinClosure and Its Role in Relational Data Analysis
We present graded extension of the algorithm LinClosure. Graded LinClosure can be used to compute degrees of semantic entailment from sets of fuzzy attribute implications. It can a...

Type Signature Induction with FCAType
Type signatures are common in modern linguistic theories. Their construction and maintenance is intricate, and therefore, an automatic induction method is desirable. In the present...

An Algorithm to Find Frequent Concepts of a Formal Context with Taxonomy
Formal Concept Analysis (FCA) considers attributes as a non-ordered set. This is appropriate when the data set is not structured. When an attribute taxonomy exists, existing techni...

Using FCA to Suggest Refactorings to Correct Design Defects
Abstract. Design defects are poor design choices resulting in a hard-tomaintain software, hence their detection and correction are key steps of a disciplined software process aimed...

Towards an Iterative Classification Based on Concept Lattice
In this paper, we propose a generic description of the concept lattice as classifier in an iterative recognition process. We also present the development of a new structural signat...

Planarity of Additively Drawn Concept Lattices
In Formal Concept Analysis, it is a very important but quite difficult task to draw line diagrams of concept lattices automatically. In particular, we want every planar lattice to ...
