Together with this years I-Semantics conference we are organizing a Linking Open Data Triplification Challenge.
The challenge aims at expediting the process of revealing and exposing structured representations, as does the DBpedia project for Wikipedia. Structured (relational) representations already back most of the existing Web sites. In addition to revealing these the challenge also aims at raising awareness in the Web Developer community and showcasing best practices.
The challenge awards attractive prices (MacBook Air, EeePC, iPod) to the most innovative and promising semantifications. The prizes are kindly sponsored by OpenLink Software, Punkt.NetServices and InfAI.
More Information about the challenge can be found at:
Outreach to the Web developer communities (as intended with the challenge) is really crucial right now to expedite the Semantic Web deployment and we would be very excited if you support this effort – e.g. by spreading the word and/or submitting to the challenge.
DBpedia exposes semantics extracted from one of the largest information sources on the Web. But one of the nice things about the Web is the variety and wealth of content (including your Blog, Wiki, CMS or other WebApp). In order to make this large variety of small Websites better mashable and bring them on the Semantic Web the makers of DBpedia released technologies, which dramatically simplify the “semantification” of your Websites. Please check out Triplify (a generic plugin for Webapps with preconfigurations for Drupal, WordPress, WackoWiki), D2RQ (a Java software for mapping and serving relational DB content for the Semantic Web) and Virtuoso (a comprehensive DB, knowledge store infrastructure).
The commonsense knowledge base Cyc or OpenCyc (when compared to DBpedia) seems to follow a rather top-down approach – first more abstract concepts and entities are represented and later Cyc started to include also more domain knowledge. This seems to be reasonable, since domain knowledge changes faster and there is much more of it. On the other hand, domain knowledge is usually, what people need to solve real problems within their domains. DBpedia contains primarily domain knowledge, hence a combination of both – Cyc and DBpedia – could really be a winning team.
Together with the committed OpenCyc community we produced a first DBpedia-Cyc linkage, which is now available as a DBpedia dataset from the downloads section. The dataset will soon also be loaded into the DBpedia SPARQL endpoint and made available as linked data. More information about the linkage can be found at: http://wiki.dbpedia.org/OpenCyc
The DBpedia Relationship Finder allows you to explore the DBpedia infobox dataset in order to find out which relations exist between two things. It can answer questions like “How are Leipzig and the Semantic Web related?“. The new version includes, amongst other changes, better algorithms and the possibility to ignore objects and properties.
The debug interface allows you to run the current version of the DBpedia extraction code against the live version of Wikipedia. Just enter a page Id like ‘Berlin’ and check what the current code extracts. Please use the debug interface to check if a bug still accures with the current code before reporting the bugs to the DBpedia bug tracker.
