Ontos is about to integrate its news portal into the Linked Data Cloud. Ontos’ GUIDs for objects are now dereferencable – the resulting RDF contains owl:sameAs-attributes to DBpedia, Freebase and others (check e. g. the entry for Barack Obama).
Within the portal Ontos crawls news articles from diverse online sources, uses its cutting-edge NLP technology to extract facts (objects and relations between them), merges these information with existing ones and stores them including respective references to the original news article – all of this fully automatically. Facts from Ontos’ portal are accessible via a RESTful HTTP API. Fetching data is free – in order to receive an API key, developers have to register (e-mail address only!) at Ontos’ homepage.
For humans Ontos provides a search interface at http://www.ontosearch.com. It allows to look-up objects in the database and viewing respective summaries in HTML or RDF.
The generated RDF does currently contain a small part of existing information (e. g. no article references yet) and owl:sameAs is only supported for Persons and Organizations. Ontos will extend the respective content step-by-step.
