The fast-growing Web 2.0 applications promote explicit social structure and explosive data on the Web, and enable the realization of social webtops, where users use web applications to collaboratively organize and share online data. In this work, we show that semantic wiki technologies are suitable for building a social webtop. We also identify two key issues in realizing social webtop applicat...

The current paper discuses the potential use of Wiki as an environment for the formation of student models during distance education sessions. The idea of student models is not novel, rather their benefits in distance education. The up growth use of Wiki environment signals the culmination of variety collaborative activities in the field of distance education. Is it proper and what is the possi...

Semantic Wikis allow users to semantically annotate their Wiki content. The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, introduce a unique and rich Wiki syntax for these annotations, and discuss how to best formally represent the augmented Wiki content. We improve existing navigation technique...

By combining the wiki concept, a web site where anyone is able to create and edit content using a web browser, with ideas fr...

Ontology construction usually requires a domain-specific corpus for building corresponding concept hierarchy. The domain corpus must have a good coverage of domain knowledge. Wikipedia(Wiki), the world’s largest online encyclopaedic knowledge source, is open-content, collaboratively edited, and free of charge. It covers millions of articles and still keeps on expanding continuously. These chara...

The organization of corporate wikis tends to deteriorate as time goes by. Rearranging categories, structuring articles and even moving sections among articles are cumbersome tasks in current wiki engines. This discourages the layman. But, it is the layman who writes the articles, knows the wiki content, and detects refactoring opportunities. Our goal is to improve the refactoring a ordances of ...

The use of social media technologies in organizations has introduced novel ways of collaboration, communication, and knowledge sharing. In this respect, the present study is concerned with examining the use of one type of social media, the wiki technology, by members of several professional communities of practice to collaborate and share knowledge with each other. As such, it seeks to identify...

Semantic wikis enable a community of users to produce formalized knowledge readable and usable by machines. To take one step further, one can use a semantic wiki as a blackboard allowing humans and machines to interact in order to build knowledge that is useful for both humans and machines. In this paper, we present a case study of the use of a semantic wiki (Semantic Media Wiki) as a blackboar...
