Introduction

The I-Semantics 2008 includes a Linking Open Data Triplification Challenge which will award three prizes to the most promising triplifications of existing Web applications, Websites and data sets. The prizes are:

• MacBook Air or Euro 1.000 (1st prize)
• Asus EeePC or Euro 300 (2nd prize)
• iPod Touch or Euro 200 (3rd prize)

The prizes are kindly sponsored by OpenLink Software and Punkt.NetServices and InfAI.

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 (some might say the only one) 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.

We envision submissions such as:

• Applications of Linked Data tools and techniques such as for example Triplify, Virtuoso or D2RQ on custom Web applications and data sets exposing a large quantity and variety of content.
• Implementations of exporters and mappers from existing content repository formats (such as mbox mailing list archives, BibTeX, XML-Schemes etc.) into RDF and Linked Data.
• Adoptions / configurations of Triplify for standard Web applications, such as for example Wikis, Weblogs, Webshops, Forums, Web-Gallery, ERP/CRM systems and Web-calendar software. You can find popular Web applications for example at SourceForge.
• Portings of the Triplify script into other Web application programming languages such as Python, Ruby, Perl, ASP. The Triplify script is very small (<300 lines of code) however, the port should be as compatible as possible with the current reference implementation but integrate well with the environment given by the programming language.
• Applications showcasing the benefits of Linked Data to end-users such as for information syndication, specialized search, browsing or augmentation of content.

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.

Criteria

Entries will be assessed according to the extent to which they:

• Demonstrate innovation through the expression of existing data structures as Linked Data.
• Reasonably reuse existing vocabularies see Documentation and alignment ontologies (e.g. DBpedia or the datasets from the LinkingOpenData cloud.
• Highlight the technical capabilities of a Semantic Web and bring benefits to potential users e.g. by on exposing data which facilitates usage and applications with an high impact.

All three criteria will be given equal importance in selecting the winning entry. In the event of a tie, the entry deemed to bring greatest benefits to potential users will be awarded the prize.

Reviews and Judging

Submissions to the Triplification Challenge will be reviewed by members of the I-Semantics Programme Committee and invited experts from the Linked Data community. Based on the reviews and the number of submissions approximately 5 to 10 submissions will be nominated for the prizes. A final decision will be made by the Organising Committee, based on the reviews by Programme Committee members.

Submissions

Submissions should consist of a 2 page description (in JUCS format) of the application, accompanied by (a link to) the software source code and a link to an online demo. The descriptions should be submitted electronically via email to Sören Auer (with the subject Triplification Challenge Submission) by June 30th, 2008. Descriptions of nominated submissions will be included in the conference proceedings. Nominations for the Triplification Challenge should be presented at the conference by their authors. Under certain circumstances (e.g. undergraduate student or open-source community contribution) the conference fee will be waived for a nominee on special request.
