Creating Fuzzy Concepts: the One-Sided Threshold, Fuzzy Closure and Factor Analysis Methods

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNAI,volume 6743))

Abstract

The two main approaches to fuzzy concept lattice creation are the one-sided threshold approach and the fuzzy closure approach. These two methods are applied to gene annotation data files that are converted into fuzzy formal contexts by translating evidence codes into a degree of evidence strength in [0, 1]. Fuzzy factor analysis is also applied to this same test data. These three methods are briefly described and then compared based on their results using the gene annotation data files.
