Wiki systems have evolved in two different ways : semantic wikis and peer to peer wikis. Semantic wikis integrate the semantic web technologies in order to improve their structure, the search and the navigation between pages. Peer-to-peer wikis offer a support for massive collaboration, off-line editing mode and an ad-hoc collaboration. The main challenge in designing a peer-to-peer semantic wi...

Wiki systems form a subclass of the more general Open Collaborative Authoring Systems, where content is created by a user community. The ability of anyone to edit the content is, at the same time, their strength and their weakness. Anyone can write documents that improve the value of the wiki-system, but this also means that anyone can introduce errors into documents, either by accident or on p...

Semantic wikis [1] establish the role of wikis as integrators of structured and semi-structured data. In this paper, we present Wikked, which is a semantic wiki turned inside out: it is a wiki engine that is embedded in the generic RDF editor Hyena. That is, Hyena edits (structured) RDF and leaves it to Wikked to display (semi-structured) wiki pages stored in RDF nodes. Wiki text has a clearly ...

During the last years wikis have become important information portals. Nevertheless, research in wiki accessibility is an often neglected topic. This paper takes a basic analytical and systematic step inside this new and complex area, explores the peculiarities, possibilities and limitations of wiki accessibility. Wikis give rise to certain accessibility limitations but also do offer new ways a...

The LACO-Wiki tool represents an open access, online portal that offers standardized land cover validation at local to global scales. LACO-Wiki integrates the LACOVAL prototype for land cover validation and the Geo-Wiki system for visualization, validation and crowdsourcing of land cover. This paper presents a conceptual overview of the LACO-Wiki system and describes the main validation workflo...

This paper reports on an ongoing experiment with using a wiki as support material for CMU-CS 15-212, a sophomore-level course on advanced programming concepts and skills. We found that the use of a wiki promotes participatory learning and encourages the students to read upcoming material before class. Future developments include pairing up the wiki with an e-tutor and supporting delivery to sma...

Project-based assignments are widely used in Computer Science courses to give students hands-on experience in using the learned knowledge to solve problems. However, despite its importance, management on student projects is usually done in an ad-hoc fashion, with varying degrees of interaction and guidance to students. This paper presents a general, Wiki-based project management framework: proj...

A wiki is a web based software which allows all visitors of a website to change its content by editing the site online in a web browser. With this key capability a wiki is an easy to use platform for collaborative working on (hyper-)texts. This paper is about the development of a wiki on QFD and all its aspects as the content of the website. The so called QFD-Wiki is not only on QFD, it is also...

OBJECTIVES Wiki systems are becoming increasingly important in university teaching. Not much is known about the opinion of lecturers of veterinary medicine regarding the active participation of students in teaching, their opinion on wiki systems and their motivation to use them in courses and to improve the quality of information. The objective of the present study was to evaluate how lecturers...

The paper presents a new semantic wiki architecture called PlWiki. The most important concept is to provide a strong knowledge representation and reasoning with Horn clauses-based representation. The idea is to use Prolog clauses on the lower level to represent facts and relations, as well as define rules on top of them. On the other hand a higher-level Semantic Web layer using RDF support is p...
