Tagging is implicitly also a social indexing process, since users share their tags and resources, constructing a social tag index, so-called folksonomy. At the same time of tagging-based system, has been popularised an interface model for visual information retrieval known as Tag-Cloud. In this model, the most frequently used tags are displayed in alphabetical order. This paper presents a novel approach to Tag-Cloud’s tags selection, and proposes the use of clustering algorithms for visual layout, with the aim of improve browsing experience. The results suggest that presented approach reduces the semantic density of tag set, and improves the visual consistency of Tag-Cloud layout.Fri Dec 21 17:31:20 CET 2007Proc. of CHIconf/chi/2007995-998Getting our head in the clouds: toward evaluation studies of tagclouds.2007tagclouds tagging visualization Fri Dec 21 17:26:37 CET 2007Tagging and Metadata for Social Information Organization Workshop, WWW07Tag-Cloud Drawing: Algorithms for Cloud Visualization2007tagclouds tagging visualization Thu Nov 29 15:24:09 CET 2007IWLS385-390VisBDD - A Web-based Visualization Framework for OBDD Algorithms.2002mypaper verification visualization www This paper presents a web-based visualization framework visBDD, indended for learning and understanding basic algorithms related to Ordered Binary Decision Diagrams (OBDDs). With visBDD the key algorithm for OBDD-synthesis, the ITE-algorithm can be explored in-depth and step-by-step by the user, while all involved data structures can be made visible at different levels of abstraction. The framework is intended as well as for students as also for professionals, who want to gain insight into the powerful OBDD data structure that is used in many verification and synthesis tools, for a better understanding of the underlying mechanisms and the problem complexity, without being dependent on reading textbooks.Sat Jun 30 12:02:28 CEST 2007International Semantic Web ConferenceDBLP:conf/semweb/200658-71Augmenting Navigation for Collaborative Tagging with Emergent Semantics.2006Semantic_Web tagging visualization Fri May 18 18:19:55 CEST 2007Merida, SpainProc.

Their solutions differ but in the end address the same two high-level issues, no matter the underlying representation paradigm: specifying (i) what information contained in RDF models should be presented (content selection) and (ii) how this information should be presented (content formatting and styling). However, each tool currently relies on its own ad hoc mechanisms and vocabulary for specifying RDF presentation knowledge, making it difficult to share and reuse such knowledge across applications. Recognizing the general need for presenting RDF content to users and wanting to promote the exchange of presentation knowledge, we designed Fresnel as a browser-independent vocabulary of core RDF display concepts. In this paper we describe Fresnel’s main concepts and present several RDF browsers and visualization tools that have adopted the vocabulary so far.Mon Nov 06 22:13:46 CET 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisGraphingwiki - a Semantic Wiki extension for visualising and inferring protocol dependency2006protocol inference semwiki2006 swikig eswc2006 wiki semantic dependency visualization This paper introduces the Graphingwiki extension to MoinMoin Wiki. Graphingwiki enables the deepened analysis of the Wiki data by augmenting it with semantic data in a simple, practical and easy-to-use manner. Visualisation tools are used to clarify the resulting body of knowledge so that only the data essential for an usage scenario is displayed. Logic inference rules can be applied to the data to perform automated reasoning based on the data. Perceiving dependencies among network protocols presents an example use case of the framework. The use case was applied in practice in mapping effects of software vulnerabilities on critical infrastructures.Thu Jul 20 20:01:06 CEST 2006Human Factors in Web DevelopmentA Zooming Web Browser1998visualization
