Hi, I'm the author of Json-Wikipedia. It's different from DB-Pedia. DBPedia converts the semistructured data containined in the infoboxes in rdf triples, while Json-Wikipedia converts ALL the content of the page (text, infoboxes, links) into a JSON object. I did this because I need some features that were not available on dbpedia (e.g., the whole text of an article, all the anchors referring to an article etc etc). Also Json-Wikipedia simplifies the processing of a Wikipedia Dump on Hadoop.
