Preface to special issue on concept lattice and their applications 2008

Abstract

The present special issue contains extended versions of selected papers that were presented at CLA 2008, the Sixth International Conference on Concept Lattices and Their Applications. CLA 2008 was held in Olomouc, Czech Republic, from October 21 to October 23, 2008, and was organized jointly by the Palacky University, Olomouc, and the State University of New York at Binghamton. CLA is an international conference dedicated to formal concept analysis (FCA) and areas closely related to FCA such as data mining, information retrieval, knowledge management, data and knowledge engineering, logic, algebra and lattice theory. In particular, the areas of interest to CLA include foundations of FCA, concept lattices and related structures, attribute implications, association rules and other data dependencies, algorithms, visualization, data preprocessing, redundancy and dimensionality reduction, classification and clustering, information retrieval, ontologies, and applications of FCA. The program of CLA 2008 consisted of presentations of regular papers and posters, and three invited talks. It is a tradition of CLA that the program chairs organize a special issue. It is our pleasure that Professor Golumbic, the Editor in Chief of the Annals of Mathematics and Artificial Intelligence, accepted our proposal to organize such special issue. We therefore invited the authors of the best CLA 2008 papers to submit extended versions of their papers to this special issue. Each submitted paper was reviewed by two to three reviewers who are renowned experts in the field. According to the journal policy, the paper co-authored by Radim Belohlavek was handled by the Editor in Chief. Based on the reviewers’ reports, eight papers were selected. We are pleased to present these papers in this special issue.
