Semantic Wikis combine properties of wikis (ease of use, low technological barrier, collaboration, easy linking) with Semantic Web technologies (structuring of knowledge, linking with background knowledge models). Since 2005, when development on the first systems startet, Semantic Wikis have matured and are now in a state where they are increasingly deployed even in domains outside the Semantic Web community or even outside Computer Science. Reasons for this are that Semantic Wikis require no advanced knowledge and are thus usable also by laymen, and that Semantic Wikis provide immeadiate benefit over „Non-Semantic“ Wikis. In addition, Semantic Wikis are also an interesting testbed for the envisioned Semantic Web and associated technologies, as Wikis have structural similarities to the Web as a whole and hence share many of the potential chances and pitfalls. This tutorial introduces into the setup and usage of the two currently most popular Semantic Wiki systems, Semantic MediaWiki and IkeWiki. Both systems will have official releases by the time the tutorial takes place, and both systems are in the focus of two upcoming EU funded projects that will start in March 2008.
