Background
DBpedia and Wikidata currently focus primarily on representing factual
knowledge as contained in Wikipedia infoboxes. A vast amount of
information, however, is contained in the unstructured Wikipedia article
texts. With the DBpedia Open Text Extraction Challenge, we aim to spur
knowledge extraction from Wikipedia article texts in order to
dramatically broaden and deepen the amount of structured
DBpedia/Wikipedia data and provide a platform for benchmarking various
extraction tools.
Mission
Wikipedia has become the ubiquitous source of knowledge for the world
enabling humans to lookup definitions, quickly become familiar with new
topics, read up background infos for news event and many more - even
settling coffee house arguments via a quick mobile research. The mission
of DBpedia in general is to harvest Wikipedia’s knowledge, refine and
structure it and then disseminate it on the web - in a free and open
manner - for IT users and businesses.
