In this paper we present GALOIS, a system that automates and applies this theory. The algorithm utilized by GALOIS to build a concept lattice is incremental and efficient, each update being done in time at most quadratic in the number of objects in the lattice. Also, the algorithm may incorporate background information into the lattice, and through clustering, extend the scope of the theory. The application we present is concerned with information retrieval via browsing, for which we argue that concept lattices may represent major support structures. We describe a prototype user interface for browsing through the concept lattice of a document-term relation, possibly enriched with a thesaurus of terms. An experimental evaluation of the system performed on a medium-sized bibliographic database shows good retrieval performance and a significant improvement after the introduction of background knowledge.

This article provides a review of this new orientation and analyzes why and how FCA and computer science attracted each other. It discusses FCA as a knowledge representation formalism using five knowledge representation principles provided by Davis, Shrobe, and Szolovits (1993). It then studies how and why mathematics-based researchers got attracted by computer science. We will argue for continuing this trend by integrating the two research areas FCA and Ontology Engineering. The second part of the article discusses three lines of research which witness the new orientation of Formal Concept Analysis: FCA as a conceptual clustering technique and its application for supporting the merging of ontologies; the efficient computation of association rules and the structuring of the results; and the visualization and management of conceptual hierarchies and ontologies including its application in an email management system.Fri Mar 28 12:11:30 CET 2008Journal of Experimental and Theoretical Artificial Intelligence189-216Comparing performance of algorithms for generating concept lattices142002formal concept OntologyHandbook FCA algorithms analysis fca algorithm Fri Mar 28 12:11:30 CET 2008Computer Networks and ISDN Systems1\&2109-117Creating a Web Analysis and Visualization Environment281995creating concept Creating OntologyHandbook Visualization web analysis visualization formal Web Analysis FCA fca Fri Mar 28 12:11:30 CET 2008Hong KongProceedings of the 6th IEEE International Conference on Data Mining (ICDM 06)December907-911TRIAS - An Algorithm for Mining Iceberg Tri-Lattices2006iceberg lattices 2006 concept tagging OntologyHandbook myown analysis tri algorithm formal triadic trias nepomuk FCA folksonomy folksonomies fca Fri Mar 28 12:11:30 CET 2008Translation of: {\it Formale Be\-griffs\-ana\-ly\-se: Mathematische Grundlagen.} Sprin\-ger, Heidelberg 1996.Formal Concept Analysis: Mathematical Foundations1999math formal concept OntologyHandbook FCA analysis fca Fri Mar 28 12:11:30 CET 2008Proc. of the 14 th Int.
