We are developing WikiNet -- a multi-language ontology by exploiting several aspects of Wikipedia. Click here to download the current version, built from the 20090703 version of the English Wikipedia. It contains a direct (index.wiki) and a reversed index (reversed_index.wiki) (both multi-lingual), and a file with relations (data.wiki). The structure is as follows:
- direct index: ConceptName ConceptID1 ConceptID2 ...
- reversed index: ConceptID1 ConceptName1 ConceptName2 ...
- relations file: ConceptID1 Relation1 ConceptID11 ConceptID12 ... ConceptID1n Relation2 ConceptID21 ConceptID22 ...
A bit more details in a README file.
There are approximately 3 million concepts, and 26+ million relations.
A toolkit for the resource will be added in the first half of 2010.
A precursor of the resource in simple text format (in English) is WikiRelations.
