OpenResearch.org launched

Posted on October 13, 2008 by Sören Auer

A large portion of their time researchers are searching for information, e.g. about calls, people, projects, tools, journals. Such information is not always easy to find and it is consequently difficult especially for young researchers or researchers crossing community boundaries to quickly get relevant information. Semantic Wiki’s are tools, where many people can collectively gather, structure and organize content – not just textually, but also semantically. In order to improve access to scientific information, increase transparency and efficiency of research, we have set up a semantic Wiki for science meta-data at: http://OpenResearch.org.

DBpedia 3.1 breaks 100 million triples barrier

Posted on August 13, 2008 by Jens Lehmann

Today, we released DBpedia 3.1. As always in the past years, the size of Wikipedia increased a lot over the past months. The new extraction contains 116,7 million triples, marking an increase of 27% over the previous version. The OpenLink team and the research group around Chris Bizer helped us to produce the release.

Apart from the more recent Wikipedia dumps we used, some notable improvements are a much better YAGO mapping, providing a more complete (more classes assigned to instances) and accurate (95% accuracy) class hierarchy for DBpedia. The Geo extractor code has been improved and is now run for all 14 languages. URI validation has switched to the PEAR validation class.

xOperator 0.2 pre-release reunion

Posted on August 6, 2008 by Sebastian Tramp

After some weeks of silence, Sebastian asked for a pre-release meeting for the 0.2 release of xOperator which we held today. We updated the issue tracker and talked about future plans and ideas. For this, Jörg and Sebastian created presentations:

We plan the xOperator 0.2 release for the last week of August. Overall, this release includes all the features which I’ve presented at the ESWC 2008 Demo session. In addition to this, we will present a web-based configuration tool where users can easily create their own xOperator setup file.

Please vote for your personal favorite (using the poll widget on the nominations page) and invite your friends and colleagues to do so as well. Although this will not have a formal influence on the committee decision the winner of the community vote will draw more attention and finally earn a honorable mention.

ParticipatoryResearch initiative launched

Posted on July 15, 2008 by Sören Auer

This ParticipatoryResearch initiative launched by AKSW aims at developing and promoting the concept of stakeholder-driven research. Goals are to (1) develop a prediction market model for research funding, (2) implement a Web platform for organising this market and the participatory research process, (3) persuade research funding agencies to use this platform for managing a part of their research portfolio.

A first step towards this goal was made with Cofundos.org – a market for open-source software R&D. The Web site of the ParticipatoryResearch initiative is hosted at: http://wiki.Cofundos.org.

CfP: International Workshop on Interacting with Multimedia Content in the Social Semantic Web (IMC-SSW 2008)

Posted on July 8, 2008 by Sebastian Tramp

Media sharing and social networking websites have attracted many millions of users resulting in vast collections of user generated content. The contents are typically poorly structured and spread over several platforms, each supporting specific media types. With the increasing growth and diversity of these websites, new ways to access and manage the contents are required – both within and across web platforms.

This workshop focuses on the interaction with these multimedia contents. We are particularly interested in contributions that follow Web 2.0 principles of simplicity and/or social navigation in combination with the representation, annotation, and linking power of the Semantic Web.

The Submission Deadline is the 14th September. A complete workshop description including topics of interest and important dates is available at http://aksw.org/Events/2008/IMCSSW.

The AKSW research group is pleased to announce that OntoWiki 0.8.5 is now available for download. Changes in this release include

as well as a bunch of bug fixes.

The project development site moved from SourceForge to GoogleCode. We have also created two new mailing lists as google groups for user support and development issues. The issue tracker moved a few weeks ago in order to prepare the release (see Goodbye SourceForge …).

Many thanks to the main contributors of this OntoWiki release: Norman Heino, Philipp Frischmuth, Christoph Rieß and Julian Jöris as well as Michael Haschke and Maria Moritz!

ESWC / SFSW 2008

Posted on May 30, 2008 by Sebastian Tramp


OntoWiki Eyetracking Screenshot

I will give a talk about our xOperator project at the European Semantic Web Conference (ESWC2008) on Tenerife next Wednesday. The xOperator is an agent for xmpp / jabber network which queries and shares trusted resources (using RDF/SPARQL) for you and your jabber friends. In addition to the full paper, we got good reviews for the demo session too. So I present the xOperator in a more technical way at the demo session on Tuesday.

Another project which we started here is RDFAPI-JS. I present this work at the Scripting for the Semantic Web Workshop (SFSW2008) which is co-located with the ESWC. RDFAPI-JS is used for RDFa widgets which can be used to modify embedded RDF models.

Thanks to Jörg, Martin and Seppl (and of course Haschek for the awesome poster) which helped me preparing the demo and the presentations. Sorry for this last week … 🙂

For more information about the projects, have a look at the following publications:
