Comments and Reviews
Said about Wikidata as an alternative
Found most of the words which DBPedia was unable to provide answers. In DBPedia 'java' and 'Java' are treated as different entities which is not in case of Wikidata.

You can start contributing without reading pages of guidelines first. The auto-suggestions are very helpful. Editing Wikidata is a lot of fun if you enjoy researching. It is mind-blown how much information can be encoded in a machine-readable format.
Wikidata is definitelly future of Wikimedia and big deal in education. It already rules and will continue!
