They share many characteristics with customer communities, but also have important differences. To explore professional peer communities, we spoke with Vanessa DiMauro, principal of Leader Networks. Vanessa has been a virtual community builder for more than 15 years, having worked with organizations such as EMC, DCI, and Cambridge Technology Partners. Her experience in interactive learning environments, knowledge management, and social networking gives her a unique perspective on what professional peer communities have to offer and how best to develop them.Fri Jan 26 03:59:10 CET 2007Proc. of the 2nd Workshop on Scripting for the Semantic Web, Colocated with ESWC 2006, Budva, MontenegroThe Semantics of Collaborative Tagging Systems2006semanticWeb web2.0 Milorad_Tosic Valentina_Milicevic tagging semantics wikipedia Wed Jan 24 20:47:13 CET 2007New York, NY, USAWWW '06: Proceedings of the 15th international conference on World Wide Web417-426Exploring social annotations for the semantic web2006technical 2006 social_software Semantic_Web acm acm_press social_annotations In order to obtain a machine understandable semantics for web resources, research on the Semantic Web tries to annotate web resources with concepts and relations from explicitly defined formal ontologies. This kind of formal annotation is usually done manually or semi-automatically. In this paper, we explore a complement approach that focuses on the "social annotations of the web" which are annotations manually made by normal web users without a predefined formal ontology. Compared to the formal annotations, although social annotations are coarse-grained, informal and vague, they are also more accessible to more people and better reflect the web resources' meaning from the users' point of views during their actual usage of the web resources. Using a social bookmark service as an example, we show how emergent semantics [2] can be statistically derived from the social annotations. Furthermore, we apply the derived emergent semantics to discover and search shared web bookmarks. The initial evaluation on our implementation shows that our method can effectively discover semantically related web bookmarks that current social bookmark service can not discover easily.Mon Jan 22 13:50:07 CET 2007DigitalOctoberManaging Learning in Virtual Settings: The Role of Context2005virtual_education John_D_Smith constructionist Smith activity_theory context virtual_communities idea_group { Managing Learning In Virtual Settings: The Role of Context discusses the basis for the development and management of learning contexts, with contributions from many diverse domains. It stresses the dimension of context in a world dominated by a focus on the dimension of content while explaining the development of balanced, organic and successful learning environments and strategies. Managing Learning In Virtual Settings: The Role of Context emphasizes the role of context in the development and management of virtual learning environments and opens up new threads in clarifying the influence of contextual issues on learning. }Sat Jan 20 07:24:57 CET 2007Learning to Eat Soup with a Knife: Counterinsurgency Lessons from Malaya and Vietnam2006John_Nagl KM military Peter_Schoomaker US Malaya UK counterinsurgency Fri Jan 12 07:24:08 CET 2007Journal of Creative Communications311-320 Book Reviews12006todo book_review CoPs Wed Jan 10 12:50:10 CET 2007Selcted Papers from the International Semantic Web Conference, 2004 - ISWC, 2004Web Semantics: Science, Services and Agents on the World Wide Web#oct#2-3211-223Flink: Semantic Web technology for the extraction and analysis of social networks32005Flink Peter_Mika ontologies foaf semantics We present the Flink system for the extraction, aggregation and visualization of online social networks. Flink employs semantic technology for reasoning with personal information extracted from a number of electronic information sources including web pages, emails, publication archives and FOAF profiles. The acquired knowledge is used for the purposes of social network analysis and for generating a web-based presentation of the community. We demonstrate our novel method to social science based on electronic data using the example of the Semantic Web research community.Wed Jan 10 12:17:57 CET 2007Boxes and ArrowsWhat is a controlled vocabulary?2002Karl_Fast controlled_vocabulary boxesandarrows Fred_Leise Mike_Steckel Mon Jan 08 10:44:01 CET 2007ESWCDBLP:conf/esws/200634-49Community-Driven Ontology Matching.20062006 Pavel_Shvaiko eswc ontology_matching semantic ontologies community-driven Anna_Zhdanova Mon Jan 08 10:41:43 CET 2007OTM Workshops (1)DBLP:conf/otm/2006-w1290-300Evaluating the Informational and Social Aspects of Participation in Online Communities.2006todo Bothorel Mon Jan 08 10:37:24 CET 2007D-Lib Magazine1Folksonomies: Tidying up Tags?122006Emma_Tonkin folksonomies tagging Marieke_Guy A folksonomy is a type of distributed classification system. It is usually created by a group of individuals, typically the resource users. Users add tags to online items, such as images, videos, bookmarks and text. These tags are then shared and sometimes refined. A general review of social bookmarking tools, one popular use area of folksonomies, was given in the April edition of D-Lib [1]. In the article the authors elaborate on the approach taken by social classification systems and the motivators behind tagging. They write, "...tags are just one kind of metadata and are not a replacement for formal classification systems such as Dublin Core, MODS, etc.... Rather, they are a supplemental means to organise information and order search results." In this article we look at what makes folksonomies work. We agree with the premise that tags are no replacement for formal systems, but we see this as being the core quality that makes folksonomy tagging so useful. We begin by looking at the issue of "sloppy tags", a problem to which critics of folksonomies are keen to allude, and ask if there are ways the folksonomy community could offset such problems and create systems that are conducive to searching, sorting and classifying. We then go on to question this "tidying up" approach and its underlying assumptions, highlighting issues surrounding removal of low-quality, redundant or nonsense metadata, and the potential risks of tidying too neatly and thereby losing the very openness that has made folksonomies so popular.Sat Jan 06 23:16:04 CET 2007Netocracy: The New Power Elite and Life After Capitalism2002Netocracy Alexander_Bard 2002 social_networks Jan_Soderqvist Sat Jan 06 02:02:14 CET 2007hasAtriple.semanticweb.org/doc/tutorial.html2004isA hasA Triple tutorial donotes Fri Jan 05 07:59:16 CET 2007AalborgProceedings of the First Conceptual Structures Tool Interoperability Workshop at the 14th International Conference on Conceptual Structures87-102{BibSonomy}: A Social Bookmark and Publication Sharing System2006social_bookmarking social_software Aldo_de_Moor bibsonomy folksonomies taocial_bookmarkinggging Andreas_Hotho Social bookmark tools are rapidly emerging on the Web. In such systems users are setting up lightweight conceptual structures called folksonomies. The reason for their immediate success is the fact that no specific skills are needed for participating. In this paper we specify a formal model for folksonomies and briefly describe our own system BibSonomy, which allows for sharing both bookmarks and publication references in a kind of personal library.Fri Jan 05 07:40:01 CET 2007Berlin/Heidelberg, GermanyInformatik-SpektrumApril2121-124Social Software292006Springer Michael_Bächle social_software article overview baechle Fri Jan 05 06:03:45 CET 2007The Semantic Web - ISWC 2006887-900Semantic Desktop 2.0: The Gnowsis ExperienceVolume 4273/20062006semantic_desktop iswc06 gnowsis Heiko_Maus Leo_Sauermann Gunnar_Aastrand_Grimnes ISWC06 Andreas_Dengel Danish_Nadeem Benjamin_Horak Malte_Kiesel Dominik_Heim Christiaan_Fluit Nepomuk EPOS In this paper we present lessons learned from building a Semantic Desktop system, the gnowsis beta. On desktop computers, semantic software has to provide stable services and has to reflect the personal view of the user. Our approach to ontologies, the Personal Information ModelPIMO allows to create tagging services like del.icio.us on the desktop. A semantic wiki allows further annotations. Continuous evaluations of the system helped to improve it. These results were created in the EPOS research project and are available in the open source projects Aperture, kaukoluwiki, and gnowsis and will be continued in the Nepomuk project. By using these components, other developers can create new desktop applications the web 2.0 way.Fri Jan 05 06:00:29 CET 2007Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisAutomatic Deployment of Semantic Wikis: a Prototype2006Wiki-Factory semantic_wikis Marco_Fabbri Valentina_Presutti Angelo_Di_Iorio MediaWiki Fabio_Vitali Semantic wikis simplify the creation, searching and management of content in a specific domain of interest. Although very powerful solutions exist for adding semantics to wikis, the authoring process of domain-oriented content still remains a manual and quite consuming task. We propose a different approach to deploy semantic wikis: the automatic delivery of a customized wiki for a given domain, taking as input an ontological description of that domain. WikiFactory is an application that takes these ideas to implementation, based on a strong distinction between the ontology designer, the content author and the graphic designer. Moreover WikiFactory is designed to be independent for a specific wiki clone and commit an abstract description of pages onto a wide set of wiki platforms. In this paper we present the early implementation of Wiki-Factory that automatically generates pages for MediaWiki.

A number of questions remain unanswered, however, regarding the nature of collaborative tagging systems including the dynamics of such systems and whether coherent classification schemes can emerge from undirected tagging by users. Currently millions of users are using collaborative tagging without centrally organizing principles, and many suspect this exhibits features considered to be indicative of a complex system. If this is the case, it remains to be seem whether collaborative tagging by users over time leads to emergent classi- fication schemes that could be formalized into an ontology usable by the Semantic Web. This paper uses data from “popular” tagged sites on the social bookmarking site del.icio.us to examine the dynamics of such collaborative tagging systems. In particular, we are trying to determine whether the distribution of tag frequencies stabilizes, which indicates a degree of cohesion or consensus among users about the optimal tags to describe particular sites. We use tag co-occurrence networks for a sample domain of tags to analyze the meaning of particular tags given their relationship to other tags and automatically create an ontology. We also produce a generative model of collaborative tagging in order to model and understand some of the basic dynamics behind the process.Fri Jan 05 05:40:14 CET 2007DecemberA del.icio.us study2004tagging del.icio.us Ulises_Mejias research 27Fri Jan 05 04:29:54 CET 2007ISSN ; -332--339Rethinking Virtual Space as a Place for Sociability: Theory and Design Implications2004Marisa_Ponti pedagogy place activity_theory Thomas_Ryberg space
