The yearly organized Linking Open Data Triplification Challenge awards prizes to the most promising triplifications of existing Web applications, Websites and data sets.
For the success of the Semantic Web it is from our point of view crucial to overcome the chicken-and-egg problem of missing semantic representations on the Web and the lack of their evaluation by standard search engines. One way to tackle this problem is to reveal and expose existing structured (relational) representations, which are already backing most of the existing Web sites. The Triplification challenge aims to expedite this process by raising awareness and showcasing best practices.
The prize of this years challenge is an MacBook Air or Euro 1.000. The prize is kindly sponsored by Ontos AG. There will also be 2nd and 3rd prizes awarded, sponsored by Punkt.Net Services and DERI.
The challenge is open to anyone interested in applying Semantic Web and Linked Data technologies. This might include students, developers, researchers, and people from industry. Individual or group submissions are both acceptable.
