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.

In such systems users are setting up lightweight conceptual structures called folksonomies. The reason for their immediate success is the fact that no specific skills are needed for participating. At the moment, however, the information retrieval support is limited. We present a formal model and a new search algorithm for folksonomies, called \emph{FolkRank}, that exploits the structure of the folksonomy. The proposed algorithm is also applied to find communities within the folksonomy and is used to structure search results. All findings are demonstrated on a large scale dataset.http://www.bibsonomy.org/bibtex/2473f5c2cca394fac0de61086082a09de/stummestumme2006-09-20T18:17:18+02:00information concept formal email search 2003 nepomuk myown retrieval analysis fca <span style="color:#555555;">Richard J. <a href="http://www.bibsonomy.org/author/Cole">Cole</a> und Peter W. <a href="http://www.bibsonomy.org/author/Eklund">Eklund</a> und Gerd <a href="http://www.bibsonomy.org/author/Stumme">Stumme</a> </span><em>Journal of Applied Artificial Intelligence (AAI)</em><em>17(3):257-280</em>(<em>2003</em>)Wed Sep 20 18:17:18 CEST 2006Journal of Applied Artificial Intelligence (AAI)3257-280Document Retrieval for Email Search and Discovery using Formal Concept Analysis172003information concept formal email search 2003 nepomuk myown retrieval analysis fca This paper discusses an document discovery tool based on conceptual clustering by formal concept analysis. The program allows users to navigate email using a visual lattice metaphor rather than a tree. It implements a virtual file structure over email where files and entire directories can appear in multiple positions. The content and shape of the lattice formed by the conceptual ontology can assist in email discovery. The system described provides more flexibility in retrieving stored emails than what is normally available in email clients. The paper discusses how conceptual ontologies can leverage traditional document retrieval systems and aid knowledge discovery in document collections.http://www.bibsonomy.org/bibtex/2a5f1a8b42409b96271bc5c671deceea9/stummestumme2006-09-20T14:52:28+02:00informationsportale information ontologies portal 2002 projekt semantic web myown project portals semiport bmbf <span style="color:#555555;">J. <a href="http://www.bibsonomy.org/author/Hartmann">Hartmann</a> und A. <a href="http://www.bibsonomy.org/author/Hotho">Hotho</a> und G. <a href="http://www.bibsonomy.org/author/Stumme">Stumme</a> </span><em>Proc.
