document: Semantic Wikipedia Wikipedia is the world 's largest collaboratively edited source of encyclopaedic knowledge . But in spite of its utility , its contents are barely machine-interpretable . Structural knowledge , e. , g. about how concepts are interrelated , can neither be formally stated nor automatically processed . Also the wealth of numerical data is only available as plain text and thus can not be processed by its actual meaning . We provide an extension to be integrated in Wikipedia , that allows the typing of links between articles and the specification of typed data inside the articles in an easy-to-use manner . Enabling even casual users to participate in the creation of an open semantic knowledge base , Wikipedia has the chance to become a resource of semantic statements , hitherto unknown regarding size , scope , openness , and internationalisation . These semantic enhancements bring to Wikipedia benefits of today 's semantic technologies : more specific ways of searching and browsing . Also , the RDF export , that gives direct access to the formalised knowledge , opens Wikipedia up to a wide range of external applications , that will be able to use it as a background knowledge base . In this paper , we present the design , implementation , and possible uses of this extension .
