AceWiki is a semantic wiki using the controlled natural language Attempto Controlled English (ACE). The use of controlled natural language makes it easy for everybody to understand the semantics of the wiki.

[edit] Introduction
AceWiki shows the formal semantics in controlled English. Thus, the users do not need to cope with complicated formal languages like RDF or OWL. Unlike most other semantic wikis, the semantics are contained directly in the article texts and not in some form of annotations. Ontological entities like individuals, concepts, and properties are mapped one-to-one to linguistic entities like proper names, nouns, of-constructs, and verbs. In order to help the users to write correct ACE sentences, AceWiki provides a predictive authoring tool.
[edit] Details
The current version was developed by Tobias Kuhn of the Attempto group of the Department of Informatics (IFI) of the University of Zurich. Loic Royer of the TU Dresden collaborated for a previous version.
The OWL reasoner Pellet is integrated into AceWiki. It ensures that the content of the wiki is always consistent. The reasoner is also used to infer the class-hierarchies and class-memberships, and the results are displayed in ACE again. Furthermore, questions can be added to the wiki articles. Those questions are evaluated by the reasoner and the answers are displayed directly in the article.
AceWiki is written in Java using the Echo Web Framework.
[edit] Demo
A demo can be found here: http://attempto.ifi.uzh.ch/acewiki
At the moment there are two exemplary wiki instances: one is about protein interactions and the other is about geographical knowledge.
