Wikis are a great tool inside the Social Web, as they provide the chance of creating collaborative knowledge in a quick way. Semantic wikis are becoming popular as Web technologies evolve: ontologies and semantic markup on the Web allow the generation of machine-readable information. Semantic wikis are often seen as small semantic webs as they provide support for enhanced navigation and searchi...

The use of Web 2.0 tools is becoming widespread in business education and educators are increasingly exploring the use of Blogs, Wikis, and Podcasts in their courses. For teaching and learning to be effective in new technology-based environments, there is a need to research and design Web 2.0 learning systems that are effective platforms for incorporating interactive tools to engage students in...

This chapter examines how collaboration and knowledge management (KM) can be supported using wikis and related tools. A wiki is a web site that makes it easy for users to create, edit, and link pages without specialized tools. Knowledge management (KM) is “the leveraging of collective wisdom to increase responsiveness and innovation” (Frappaolo, 2006, p. 8). The chapter seeks to help readers un...

Semantic wikis are very promising tools for producing structured and unstructured data. However, they suffer from a lack of user provided semantic annotations, resulting in a loss of efficiency, despite of their high potential. This paper focuses on an original way to encourage users to annotate semantically pages. We propose a system that suggests automatically computed annotations to users. U...

Wikis are often considered as being a wide source of information. However, identifying provenance information about their content is crucial, whether it is for computing trust in public wiki pages or to identify experts in corporate wikis. In this paper, we address this issue by providing a lightweight ontology for provenance management in wikis, based on the W7 model. Furthermore, we showcase ...

Although wikis have gained considerable attention in higher education, students are often reluctant to use wikis in formal learning processes. Unlike company employees, students are not often rewarded for their participation in wiki-based assignments. Therefore, students seem to be opportunistic and decide to adopt wikis if they fit their current situation and preferences. This paper adapts the...

Wikis tend to be used more and more in world-wide, intranet and increasingly even in personal settings. Current wikis are data islands. They are open for everyone to contribute, but closed for machines and automation. In this paper we define a wiki interchange format (WIF) that allows data exchange between wikis and related tools. Different from other approaches, we also tackle the problem of p...

The undo mechanism is an essential feature in collaborative editing systems. Most popular semantic wikis support a revert feature, some provide an undo feature to remove any modification at any time. However this undo feature does not always succeed. Supporting the undo mechanism for P2P semantic wikis has never been tackled. In this paper, we present an undo approach for Swooki, the first P2P ...

Wikis are prominent for successfully supporting the quick and simple creation, sharing and management of content on the web. Semantic wikis improve this by semantically enriched content. Currently, notable advances in different fields of semantic technology like (paraconsistent) reasoning, expressive knowledge (e.g., rules), and ontology learning can be observed. By making use of these technolo...

Wikis have originally emerged and are most commonly known as social software, but there is also a growing trend to use wikis as a learning and assessment tool in Higher Education. The latter is the focus of the present paper. The effects of task type and instructions on students’ decisions about wiki structure and navigation are considered by examining group wikis created by students of two pos...
