This has major implications for businesses across the globe because their commercial advantage relies on the optimal exploitation of their own enterprise information, the huge volumes of online information, and the productivity of the required knowledge work. The Active project addresses this challenge through an integrated knowledge management workspace that reduces information overload by significantly improving the mechanisms for creating, managing, and using information. The project's approach follows three themes: sharing information through tagging, wikis, and ontologies; prioritizing information delivery by understanding users' current-task context; and leveraging informal processes that are learned from user behavior.Thu Jan 06 14:48:21 CET 2011IT Professional434-41Understanding Web 2.092007application bookmark tagging zzz.a.it09 paper web blog ieee software newsfeeds v1010 social wiki Web 2.0, the second phase in the Web's evolution, is attracting the attention of IT professionals, businesses, and Web users. Web 2.0 is also called the wisdom Web, people-centric Web, participative Web, and read/write Web. Web 2.0 harnesses the Web in a more interactive and collaborative manner, emphasizing peers' social interaction and collective intelligence, and presents new opportunities for leveraging the Web and engaging its users more effectively. Within the last two to three years, Web 2.0, ignited by successful Web 2.0 based social applications such as MySpace, Flickr, and YouTube, has been forging new applications that were previously unimaginable.Sun Oct 31 22:46:01 CET 2010M{\"u}nchen3.Web 2.0: Konzepte, Anwendungen, Technologien2008information application tagging data web blog software newsfeeds v1010 social ajax book wiki management Ajax, Rails und RSS sind in aller Munde. Doch weit mehr als diese Technologien -- Basis vieler Web 2.0-Anwendungen -- sind es die neuen Nutzerschichten und die ver{\"a}nderte Art und Weise seiner Nutzung, die das Web 2.0 so neuartig machen. Das Buch von Tom Alby ist daher auch kein weiteres Buch zu Web 2.0-Techniken. Vielmehr behandelt es die Konzepte, ohne die man die Vorteile des Web 2.0, die sich vor allem Unternehmen bieten, verschenkt. Tom Alby untersucht die unterschiedlichen Ans{\"a}tze und Gesch{\"a}ftsmodelle von Web 2.0-Anwendungen -- Wikis, Blogs und Podcasts, Social Software, Folksonomy und User Generated Software -- und zeigt Gemeinsamkeiten wie auch Unterschiede auf.

DBpedia allows you to ask sophisticated queries against datasets derived from Wikipedia and to link other datasets on the Web to Wikipedia data. We describe the extraction of the DBpedia datasets, and how the resulting information is published on the Web for human- and machine-consumption. We describe some emerging applications from the DBpedia community and show how website authors can facilitate DBpedia content within their sites. Finally, we present the current status of interlinking DBpedia with other open datasets on the Web and outline how DBpedia could serve as a nucleus for an emerging Web of open data.Sun Oct 31 22:40:56 CET 2010The Semantic Web: Research and Applications, 4th European Semantic Web Conference, ESWC 2007, Innsbruck, AustriaESWC2007503-517What Have Innsbruck and Leipzig in Common? Extracting Semantics from Wiki Content2007information ai knowledge springer zzz.th v1010 paper processing semantic web wiki extraction Wikis are established means for the collaborative authoring, versioning and publishing of textual articles. The Wikipedia project, for example, succeeded in creating the by far largest encyclopedia just on the basis of a wiki. Recently, several approaches have been proposed on how to extend wikis to allow the creation of structured and semantically enriched content. However, the means for creating semantically enriched structured content are already available and are, although unconsciously, even used by Wikipedia authors. In this article, we present a method for revealing this structured content by extracting information from template instances. We suggest ways to efficiently query the vast amount of extracted information (e.g. more than 8 million RDF statements for the English Wikipedia version alone), leading to astonishing query answering possibilities (such as for the title question). We analyze the quality of the extracted content, and propose strategies for quality improvements with just minor modifications of the wiki systems being currently used.Sun Oct 31 22:39:32 CET 2010Computer234-41Wikis: From Each According to His Knowledge412008information software ieee v1010 paper web team wiki management Wikis offer tremendous potential to capture knowledge from large groups of people, making tacit, hidden content explicit and widely available.

On top of the structured information in the wiki, novel ways to search, browse, and present the wiki content become possible. However, while powerful query languages offer new opportunities for semantic search, the syntax of formal query languages is not adequate for end users. In this work we present an approach to semantic search that combines the expressiveness and capabilities of structured queries with the simplicity of keyword interfaces and faceted search. Users articulate their information need in keywords, which are translated into structured, conjunctive queries. This translation may result in multiple possible interpretations of the information need, which can then be selected and further refined by the user via facets. We have implemented this approach to semantic search as an extension to Semantic MediaWiki. The results of a user study in the SMW-based community portal semanticweb.org show the efficiency and effectiveness of the approach as well as its ease of use.Fri Oct 29 17:03:22 CEST 2010Web Semantics#sep#3154-165{DBpedia}---A Crystallization Point for the Web of Data72009information ai knowledge zzz.th v1010 paper rdf processing semantic web wiki extraction The DBpedia project is a community effort to extract structured information from Wikipedia and to make this information accessible on the Web. The resulting DBpedia knowledge base currently describes over 2.6 million entities. For each of these entities, DBpedia defines a globally unique identifier that can be dereferenced over the Web into a rich RDF description of the entity, including human-readable definitions in 30 languages, relationships to other resources, classifications in four concept hierarchies, various facts as well as data-level links to other Web data sources describing the entity. Over the last year, an increasing number of data publishers have begun to set data-level links to DBpedia resources, making DBpedia a central interlinking hub for the emerging Web of Data. Currently, the Web of interlinked data sources around DBpedia provides approximately 4.7 billion pieces of information and covers domains such as geographic information, people, companies, films, music, genes, drugs, books, and scientific publications. This article describes the extraction of the DBpedia knowledge base, the current status of interlinking DBpedia with other data sources on the Web, and gives an overview of applications that facilitate the Web of Data around DBpedia.Fri Oct 29 17:01:53 CEST 2010Web Semantics184-97{SweetWiki:} A Semantic Wiki62008software ai knowledge v1010 paper community data processing semantic web wiki management Everyone agrees that user interactions and social networks are among the cornerstones of Web 2.0. Web 2.0 applications generally run in a web browser, propose dynamic content with rich user interfaces, offer means to easily add or edit content of the web site they belong to and present social network aspects. Well-known applications that have helped spread Web 2.0 are blogs, wikis, and image/video sharing sites; they have dramatically increased sharing and participation among web users. It is possible to build knowledge using tools that can help analyze users’ behavior behind the scenes: what they do, what they know, what they want. Tools that help share this knowledge across a network, and that can reason on that knowledge, will lead to users who can better use the knowledge available, i.e., to smarter users. Wikipedia, a wildly successful example of web technology, has helped knowledge-sharing between people by letting individuals freely create and modify its content. But Wikipedia is designed for people---today's software cannot understand and reason on Wikipedia's content. In parallel, the semantic web, a set of technologies that help knowledge-sharing across the web between different applications, is starting to gain attraction. Researchers have only recently started working on the concept of a semantic wiki, mixing the advantages of the wiki and the technologies of the semantic web. In this paper we will present a state-of-the-art of semantic wikis, and we will introduce SweetWiki, an example of an application reconciling two trends of the future web: a semantically augmented web and a web of social applications where every user is an active provider as well as a consumer of information. SweetWiki makes heavy use of semantic web concepts and languages, and demonstrates how the use of such paradigms can improve navigation, search, and usability.Fri Oct 29 16:59:22 CEST 2010Information SciencesSpecial Issue on Intelligent Distributed Information Systems101850-1864A Contribution-based Framework for the Creation of Semantically-enabled Web Applications1802010application ai v1010 paper tool semantic web zzz.th.c4 wiki interface user design We present Fortunata, a wiki-based framework designed to simplify the creation of semantically-enabled web applications. This framework facilitates the management and publication of semantic data in web-based applications, to the extent that application developers do not need to be skilled in client-side technologies, and promotes application reuse by fostering collaboration among developers by means of wiki plugins. We illustrate the use of this framework with two Fortunata-based applications named OMEMO and VPOET, and we evaluate it with two experiments performed with usability evaluators and application developers respectively. These experiments show a good balance between the usability of the applications created with this framework and the effort and skills required by developers.Fri Oct 29 16:58:41 CEST 2010Informatik-Spektrum6434-439{Semantic Wiki}302007knowledge springer v1010 paper semantic web wiki management Das Thema Semantic Wikis als Verkn{\"u}pfung von Wiki-Konzepten mit semantischen Technologien gewann in den vergangenen Jahren zunehmend an Bedeutung, weil es ,soziale Intelligenz und k{\"u}nstliche Intelligenz miteinander verkn{\"u}pft.
