Ideas and Improvements for Semantic Wikis

Abstract

Abstract. We present an architecture for combining wikis containing hypertext with ontologies containing formal, structured information. A web-based ontology editor that supports collaborative work through versioning, transactions and management of simultaneous modifications is used for ontology evolution. In wiki pages, ontology information can be used to render dynamic content and answer user queries. Furthermore, query templates are introduced that simplify the use of queries for inexperienced users. The architecture allows easy integration with existing ontology frameworks and wiki engines. The usefulness of the approach is demonstrated by a prototypical implementation as well as a small case study.

Collaborative management of web ontology data with flexible access control

“…There exist other semantic wiki systems (e.g., WikSAR (Aumueller & Auer, 2005); COW (Fischer, Gantner, Stritt, Rendle, & Schmidt-Thieme, 2006); WikiFactory (Iorio, Presutti, & Vitali, 2006)) which provide more features such as integration with desktops (Aumueller & Auer, 2005), typical query mechanisms (Fischer et al, 2006), domain-oriented design (Iorio et al, 2006), and so on. The investigation shows that most wiki systems do not have a sophisticated mechanism to control the operations on the contents.…”

Using semantic Wikis as collaborative tools for geo-ontology

“…Jochen discussed the locking strategy for ontology elements [9]. We made use of the locking strategy for the synchronization of ontology; the version service extended from the Wikis' for ontology version.…”

“…For semantic Wikis, a third group can be detected which called "experts": People with sufficient understanding of knowledge representation mechanisms to contribute to the semantic data of the web site, especially the ontology structure. Jochen pointed out that, for the success of a semantic Wiki it is crucial that the system is capable of serving the needs of all three groups [9]. In the WikiFactory application, accomplished by Angelo for creating domain-oriented Wikis, two different users were identified: an expert ontology designer and the final users.…”

“…SPARQL, controlled natural language and full text search are exploited for querying knowledge. Creating SPARQL templates has been discussed using ontology in Wikis [9]. The AceWiki project presents the knowledge in OWL and ACE (Attempto Controlled English, kind of controlled natural language) [11].…”

Flavors of KWQL, a Keyword Query Language for a Semantic Wiki

“…While the need for simple but powerful retrieval of semantic information in semantic wikis has been pointed out [25], current semantic wikis use either simple full-text search [18,10,1,20], allow querying of annotations using a traditional query language like SPARQL, or both [11,29,28,23,2,27]; however in the latter case, the two are not integrated but used separately. Embedded queries, a form of views, are possible in several semantic wikis [25].…”
