Projects

AKSW has launched a number of high-impact R&D projects.

SoftWiki

SoftWiki – distributed, end-user-centred Requirements Engineering for evolutionary Software Development
National Research Project, funded by the German Federal Ministry of Education and Research, part of the research initiative “Software Engineering 2006”

OntoWiki

OntoWiki is a semantic collaboration platform implementing the Web 2.0 idea of an architecture of participation for the collaborative development of Semantic Web knowledge bases. Onto Wiki is implemented as an alternative user interface for Powl and included in the latest Powl distribution.

Impact: more than 8.000 downloads of the OntoWiki software (since 2004) / 773 in Sep 2007, on average 3.000 monthly visitors at http://Ontowiki.net, serving a broad variety of industrial and academic users.

Triplify

Triplify tackles the chicken-and-egg problem of the Semantic Web by providing a building block for the “semantification” of Web applications. Triplify provides small, light-weight plugins for database-backed Web applications and exposes semantics as RDF, Linked Data and JSON.

Cofundos

Cofundos.org is a platform for community innovation and funding of open source software; many individual donations and contributions are pooled together in order to realize intelligent software ideas.

Impact: more than 10.000 visitors in Oct 2007, 62 Blog posts (according to Technorati), News about Cofundos in major news channels (e.g. Heise.de, Golem.de, Linux.com), more than 300 registered users, more than 5k€ pledged donations in Oct 2007.

DBpedia

DBpedia is a community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia and to link other datasets on the Web to Wikipedia data.

Impact: 300 posts about DBpedia in the Blogosphere (according to Technorati), ca. 100.000 visitors at the DBpedia website in 2007, on average 350 daily visitors. DBpedia has become the most popular dataset used with Semantic Web applications and research prototypes.

DL-Learner

DL-Learner is a tool for learning concepts in Description Logics (DLs) from user-provided examples. Equivalently, it can be used to learn classes in OWL ontologies from selected objects. The goal of DL-Learner is to support knowledge engineers in constructing knowledge and learning about the data they created.

Pediax

Pediax is a Wikipedia browser/mirror, consequently exploiting Web 2.0 technologies such as AJAX for an enhanced user experience. Pediax includes a geo-browsing mashup which displays 60.000 geo-referenced Wikipedia articles on a world map. Pediax is currently visited over 50.000 times per month and will serve as a showcase for the semantic Wikipedia extraction.

xOperator

xOperator combines advantages of social network websites with instant messaging. It tries to be a semantic agent for xmpp / jabber network which finds and shares content about resources (using RDF/SPARQL) for you and your jabber friends.

Powl

Powl is a Semantic Web application development framework featuring a comprehensive API for handling RDF, RDFS and OWL, a library of semantic widgets and a web-based user interface. Powl is implemented for the most widely deployed web application environment: PHP and My SQL. Powl has been downloaded over 3.000 times and has an active developer and user community.
