DBpedia 2.0, Open Knowledge Foundation Weblog, September 10, 2007. Excerpt:
Comment. DBpedia harvests from Wikipedia because Wikipedia is large and free. But something similar could be done with unfree databases. The trick (apart from access) is to extract uncopyrightable facts and paraphrased assertions, not copyrighted expressions. Wikipedia may be the inexpensive way to prove the concept, but the concept is of much wider application. See some examples of DBpedia fact and assertion harvesting, and let your imagination run free. |
