In such systems users are setting up lightweight conceptual structures called folksonomies. Unlike ontologies, shared conceptualizations are not formalized, but rather implicit. We present a new data mining task, the mining of all frequent tri-concepts, together with an efficient algorithm, for discovering these implicit shared conceptualizations. Our approach extends the data mining task of discovering all closed itemsets to three-dimensional data structures to allow for mining folksonomies. We provide a formal definition of the problem, and present an efficient algorithm for its solution. Finally, we show the applicability of our approach on three large real-world examples.http://www.bibsonomy.org/bibtex/226ff196335caf137b1862d050bc1c515/schmitzschmitz2007-01-26T16:34:26+01:00fca triadic folksonomy trias algorithm tagging myown 2006 <span style="color:#555555;">Robert <a href="http://www.bibsonomy.org/author/Jäschke">J&#228;schke</a> und Andreas <a href="http://www.bibsonomy.org/author/Hotho">Hotho</a> und Christoph <a href="http://www.bibsonomy.org/author/Schmitz">Schmitz</a> und Bernhard <a href="http://www.bibsonomy.org/author/Ganter">Ganter</a> und Gerd <a href="http://www.bibsonomy.org/author/Stumme">Stumme</a> </span><em>Hong Kong, </em><em>December2006. </em><em>(to appear) . </em>Fri Jan 26 16:34:26 CET 2007Hong KongProc. 6th ICDM conferenceDecember(to appear)TRIAS - An Algorithm for Mining Iceberg Tri-Lattices2006fca triadic folksonomy trias algorithm tagging myown 2006 http://www.bibsonomy.org/bibtex/2ae14b00b5489de8da6e4578ac3062bfc/schmitzschmitz2006-04-05T12:18:22+02:00fca <span style="color:#555555;">Bernhard <a href="http://www.bibsonomy.org/author/Ganter">Ganter</a> und Rudolf <a href="http://www.bibsonomy.org/author/Wille">Wille</a> </span><em>Springer, </em><em>Berlin -- Heidelberg, </em>(<em>1999</em>)Wed Apr 05 12:18:22 CEST 2006Berlin -- HeidelbergFormal Concept Analysis: Mathematical Foundations1999fca http://www.bibsonomy.org/bibtex/2468f01390bf3c74843de096a5d79b293/schmitzschmitz2006-01-31T08:54:37+01:00triadic folksonomy fca context <span style="color:#555555;">Gerd <a href="http://www.bibsonomy.org/author/Stumme">Stumme</a> </span><em>Proc. 3rd Intl.
