Two days of presentations, demos and discussions about Social Semantic Web approaches, tools and benefits are over. We had more participants than expected - social semantic collaboration seems to be indeed a hot topic. Kingsley Idehen’s keynote about the Data Web did not just excite CSSW participants but visitors of other SABRE conferences as well. We were very happy to incorporate some late breaking additions to the program, among them Santtu Toivonen’s talk about “Web on the Move - Landscapes of Mobile Social Media” and Marc Fleischmann’s inspiring sMeet presentation “sMeet - Bringing a Rich and Realistic Communication Experience to the Global Virtual Society”. CSSW concluded on Thursday with a panel discussion about obstacles and benefits of the Social Semantic Web and a come together in the restaurant Pier1 at lake Cosupden.

The Conference on Social Semantic Web, which is co-organized by AKSW started today with a keynote by Kingsley Idehen. We look forward to two days of paper presentations, demos, discussions and hands-on-work. More information about the program can be found at http://aksw.org/cssw.

Graz is really a nice city with many cultural places of interest and a great old city center with small alley and this castle hill.

The AKSW group announces the first release of DL-Learner, which we open sourced recently. DL-Learner is available for download at its sourceforge.net project page. Its goal is to learn class definitions from examples. To do this, it implements various learning algorithms, supports different input formats, and can make use of different OWL reasoners. DL-Learner provides a command line interface and a separately released PHP web interface.
