LOD Triplification Challenge 2009
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 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.
On Friday the winners of this year's Triplification Challenge were announced at I-Semantics 2009 in Graz. The winners are:
- 1st prize: Anja Jentzsch, Jun Zhao, Oktie Hassanzadeh, Kei-Hoi Cheung, Matthias Samwald, Bo Andersson with Linking Open Drug Data
- 2nd prize: Bernhard Schandl with TripFS: Exposing File Systems as Linked Data
- 3rd prize: Matthias Quasthoff, Sebastian Hellmann, Konrad Höffner with Standardized Multilingual Language Resources for the Web of Data: http://corpora.uni-leipzig.de/rdf
We received a number of very high-quality submissions and decided to award two honorable mentions to:
- Danh Le Phuoc with SensorMasher: publishing and building mashup of sensor data
- Andreas Koller with SKOS Thesaurus Management based on Linked Data with Poolparty
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. We envision submissions such as (but not limited to) the following:
- 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, Bib Te X, 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 Source Forge.
- 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.
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 and alignment ontologies (e.g., the datasets from the Linking Open Data 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 Organizing Committee, based on the reviews by Programme Committee members.
Submissions should consist of a two page description in JUCS format of the application, accompanied by (a link to) the software source code and a link to an online demo. Note that either the data or the source code must be open, ideally both.
The descriptions should be submitted electronically via email to Michael Hausenblas with the subject Triplification Challenge Submission by August 9th, 2009. Descriptions of nominated submissions will be included in the conference proceedings of the I-Semantics. 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.
