This paper unifies prominent characterizations of layout quality and clustering quality, by showing that energy models of pairwise attraction and repulsion subsume Newman and Girvan's modularity measure. Layouts with optimal energy are relaxations of, and are thus consistent with, clusterings with optimal modularity, which is of practical relevance because both representations are complementary and often used together.tagging, communities, vocabulary, evolutionhttp://www.bibsonomy.org/bibtex/2582641c05e7a0b9396945a951822c83f/stummestumme2008-03-10T20:03:40+01:00communities community vocabulary evolution tagging folksonomy folksonomies <span style="color:#555555;">Shilad <a href="http://www.bibsonomy.org/author/Sen">Sen</a> und Shyong K. <a href="http://www.bibsonomy.org/author/Lam">Lam</a> und Al Mamunur <a href="http://www.bibsonomy.org/author/Rashid">Rashid</a> und Dan <a href="http://www.bibsonomy.org/author/Cosley">Cosley</a> und Dan <a href="http://www.bibsonomy.org/author/Frankowski">Frankowski</a> und Jeremy <a href="http://www.bibsonomy.org/author/Osterhouse">Osterhouse</a> und F. <a href="http://www.bibsonomy.org/author/Maxwell Harper">Maxwell Harper</a> und John <a href="http://www.bibsonomy.org/author/Riedl">Riedl</a> </span><em>CSCW '06: Proceedings of the 2006 20th anniversary conference on Computer supported cooperative work, </em><em>Seite181--190. </em><em>New York, NY, USA, </em><em>ACM, </em>(<em>2006</em>)Mon Mar 10 20:03:40 CET 2008New York, NY, USACSCW '06: Proceedings of the 2006 20th anniversary conference on Computer supported cooperative work181--190tagging, communities, vocabulary, evolution2006communities community vocabulary evolution tagging folksonomy folksonomies A tagging community's vocabulary of tags forms the basis for social navigation and shared expression.We present a user-centric model of vocabulary evolution in tagging communities based on community influence and personal tendency. We evaluate our model in an emergent tagging system by introducing tagging features into the MovieLens recommender system.We explore four tag selection algorithms for displaying tags applied by other community members. We analyze the algorithms 'effect on vocabulary evolution, tag utility, tag adoption, and user satisfaction.http://www.bibsonomy.org/bibtex/2e1ce1b53c051efa1892dbc3b09643c31/stummestumme2007-12-14T17:14:10+01:00community communities detection web <span style="color:#555555;">Ravi <a href="http://www.bibsonomy.org/author/Kumar">Kumar</a> und Prabhakar <a href="http://www.bibsonomy.org/author/Raghavan">Raghavan</a> und Sridhar <a href="http://www.bibsonomy.org/author/Rajagopalan">Rajagopalan</a> und Andrew <a href="http://www.bibsonomy.org/author/Tomkins">Tomkins</a> </span><em>Computer Networks</em><em>31(11--16):1481--1493</em>(<em>1999</em>)Fri Dec 14 17:14:10 CET 2007Computer Networks 11--161481--1493Trawling the {Web} for emerging cyber-communities311999community communities detection web [0705.1013] Tracking User Attention in Collaborative Tagging Communitieshttp://www.bibsonomy.org/bibtex/2785df87d0942d1cb6da9b944df902730/stummestumme2007-12-13T12:02:36+01:00Tagging citeulike Communities user tracking User folksonomy communities bibsonomy <span style="color:#555555;">Elizeu <a href="http://www.bibsonomy.org/author/Santos-Neto">Santos-Neto</a> und Matei <a href="http://www.bibsonomy.org/author/Ripeanu">Ripeanu</a> und Adriana <a href="http://www.bibsonomy.org/author/Iamnitchi">Iamnitchi</a> </span>(<em>2007</em>)Thu Dec 13 12:02:36 CET 2007Tracking User Attention in Collaborative Tagging Communities2007Tagging citeulike Communities user tracking User folksonomy communities bibsonomy http://www.bibsonomy.org/bibtex/22b6be3bd5daee7119973fcf69909956f/stummestumme2007-03-22T17:47:57+01:00myown l3s bibsonomy tagging detection 2006 community nepomuk communities <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 Gerd <a href="http://www.bibsonomy.org/author/Stumme">Stumme</a> </span><em>Proc. 18.

In diesen Systemen können Benutzer gemeinsam Ressourcen verwalten und mit Schlagwörtern versehen. Die dadurch entstehenden begrifflichen Strukturen stellen ein interessantes Forschungsfeld dar. Dieser Artikel untersucht Ansätze und Wege zur Entdeckung und Strukturierung von Nutzergruppen ("Communities") in Folksonomies.http://www.bibsonomy.org/bibtex/2b356c4c84555d3b4d013b773ab867c8c/stummestumme2006-05-19T14:46:06+02:00mining communities web structure <span style="color:#555555;">Ravi <a href="http://www.bibsonomy.org/author/Kumar">Kumar</a> und Prabhakar <a href="http://www.bibsonomy.org/author/Raghavan">Raghavan</a> und Sridhar <a href="http://www.bibsonomy.org/author/Rajagopalan">Rajagopalan</a> und Andrew <a href="http://www.bibsonomy.org/author/Tomkins">Tomkins</a> </span><em>Computer Networks</em><em>31(11-16):1481-1493</em>(<em>1999</em>)Fri May 19 14:46:06 CEST 2006Computer Networks11-161481-1493Trawling the Web for Emerging Cyber-Communities.311999mining communities web structure kddhttp://www.bibsonomy.org/bibtex/2923fe2e2d6a389c74c679d4f1f9a2a5e/stummestumme2005-12-16T17:54:52+01:00communities <span style="color:#555555;">Harith <a href="http://www.bibsonomy.org/author/Alani">Alani</a> und Srinandan <a href="http://www.bibsonomy.org/author/Dasmahapatra">Dasmahapatra</a> und Kieron <a href="http://www.bibsonomy.org/author/O&#039;Hara">O'Hara</a> und Nigel <a href="http://www.bibsonomy.org/author/Shadbolt">Shadbolt</a> </span><em>IEEE Intelligent Systems</em><em>18(2):18-25</em><em>March/April2003. </em>Fri Dec 16 17:54:52 CET 2005IEEE Intelligent SystemsMarch/April218-25{I}dentifying {C}ommunities of {P}ractice through {O}ntology {N}etwork {A}nalysis182003communities
