Using data mining methods from FCA and graph analysis, we investigate patterns and communities among authors, we identify and visualize influential publications and authors, and we give a statistical summary of the conferences’ history. %Z %U https://www.kde.cs.uni-kassel.de/pub/pdf/doerfel2012publication.pdf %+ %^ %0 %0 Journal Article %A Jäschke, Robert; Hotho, Andreas; Schmitz, Christoph; Ganter, Bernhard & Stumme, Gerd %D 2008 %T Discovering Shared Conceptualizations in Folksonomies %E %B Journal of Web Semantics %C %I %V 6 %6 %N 1 %P 38-53 %& %Y %S %7 %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 %3 article %4 %# %$ %F jaeschke08discovering %K 2008, FCA, OntologyHandbook, analysis, bibsonomy, concept, discovering, fca, folksonomies, formal, itegpub, l3s, myown, shared, triadic %X %Z %U http://dx.doi.org/10.1016/j.websem.2007.11.004 %+ %^ %0 %0 Book Section %A Cimiano, Philipp; Hotho, Andreas; Stumme, Gerd & Tane, Julien %D 2004 %T Conceptual Knowledge Processing with Formal Concept Analysis and Ontologies %E Eklund, Peter %B Concept Lattices %C Berlin/Heidelberg %I Springer %V 2961 %6 %N %P 189--207 %& %Y %S Lecture Notes in Computer Science %7 %8 %9 %? %! %Z %@ 978-3-540-21043-6 %( %) %* %L %M %1 %2 %3 incollection %4 %# %$ %F cimiano2004conceptual %K 2004, citedBy:doerfel2012publication, fca, icfca, itegpub, knowledge, l3s, myown, processing %X %Z %U http://dx.doi.org/10.1007/978-3-540-24651-0_18 %+ %^ %0 %0 Conference Proceedings %A Stumme, Gerd %D 2004 %T Iceberg Query Lattices for Datalog %E Wolff, Karl Erich; Pfeiffer, Heather D. & Delugach, Harry S. %B Conceptual Structures at Work: 12th International Conference on Conceptual Structures (ICCS 2004) %C Heidelberg %I Springer %V 3127 %6 %N %P 109-125 %& %Y %S LNCS %7 %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 Publications of Gerd Stumme %3 inproceedings %4 %# %$ %F stumme2004iceberg %K 2004, analysis, concept, context, datalog, families, family, fca, formal, iceberg, itegpub, l3s, lattices, myown, pcf, power, queries, query %X %Z %U http://www.kde.cs.uni-kassel.de/stumme/papers/2004/stumme2004iceberg.pdf %+ %^ %0 %0 Journal Article %A Stumme, Gerd; Taouil, Rafik; Bastide, Yves; Pasquier, Nicolas & Lakhal, Lotfi %D 2002 %T Computing iceberg concept lattices with TITANIC %E %B Data \& Knowledge Engineering %C %I Elsevier Science Publishers B.

Iceberg lattices are a conceptual clustering method, which is well suited for analyzing very large databases. They also serve as a condensed representation of frequent itemsets, as starting point for computing bases of association rules, and as a visualization method for association rules. Iceberg concept lattices are based on the theory of Formal Concept Analysis, a mathematical theory with applications in data analysis, information retrieval, and knowledge discovery. We present a new algorithm called TITANIC for computing (iceberg) concept lattices. It is based on data mining techniques with a level-wise approach. In fact, TITANIC can be used for a more general problem: Computing arbitrary closure systems when the closure operator comes along with a so-called weight function. The use of weight functions for computing closure systems has not been discussed in the literature up to now. Applications providing such a weight function include association rule mining, functional dependencies in databases, conceptual clustering, and ontology engineering. The algorithm is experimentally evaluated and compared with Ganter's Next-Closure algorithm. The evaluation shows an important gain in efficiency, especially for weakly correlated data. %Z %U http://portal.acm.org/citation.cfm?id=606457 %+ %^
