Detecting Users' Motivation for Tagging in Social Tagging Systems2010Social Tagging While recent progress has been achieved in understanding the structure and dynamics of social tagging systems, we know little about the underlying user motivations for tagging, and how they influence resulting folksonomies and tags. This paper addresses three issues related to this question: 1.) What motivates users to tag resources, and in what ways is user motivation amenable to quantitative analysis? 2.) Does users' motivation for tagging vary within and across social tagging systems, and if so how? and 3.) How does variability in user motivation influence resulting tags and folksonomies? In this paper, we present measures to detect whether a tagger is primarily motivated by categorizing or describing resources, and apply the measures to datasets from 8 different tagging systems. Our results show that a) users' motivation for tagging varies not only across, but also within tagging systems, and that b) tag agreement among users who are motivated by categorizing resources is significantly lower than among users who are motivated by describing resources. Our findings are relevant for (i) the development of tag recommenders, (ii) the analysis of tag semantics and (iii) the design of search algorithms for social tagging systems.Sat Feb 11 19:24:16 CET 2012BerlinResearch and Advanced Technology for Digital Libraries461--465Lecture Notes in Computer ScienceExploring the Influence of Tagging Motivation on Tagging Behavior62732010imported The reasons why users tag have remained mostly elusive to quantitative investigations. In this paper, we distinguish between two types of motivation for tagging: While categorizers use tags mainly for categorizing resources for later browsing, describers use tags mainly for describing resources for later retrieval. To characterize users with regard to these different motivations, we introduce statistical measures and apply them to 7 different real-world tagging datasets. We show that while most taggers use tags for both categorizing and describing resources, different tagging systems lend themselves to different motivations for tagging. Additionally we show that the distinction between describers and categorizers can improve the performance of tag recommendation.Fri Feb 10 00:00:00 CET 2012IEEE Communications Letters7586-588Rate Optimization for 2D OFDM Relaying.112007dblp Fri Feb 10 00:00:00 CET 2012ICIC (1)conf/icic/2011-1147-152Lecture Notes in Computer ScienceLocal Meta-models for ASM-MOMA.68382011dblp Thu Feb 09 00:00:00 CET 2012Simulation2233-251Pseudo bond graph modeling of wastewater treatment bioprocesses.882012dblp Thu Feb 09 00:00:00 CET 2012ISAIMconf/isaim/2008Exploiting Conjunctive Queries in Description Logic Programs.2008dblp Tue Feb 07 00:00:00 CET 2012Theor.
