I'd like to get an instance of DBpedia data, for example on the service provided by Kingsley . But I wonder how often DBpedia is updated, if new articles are created on Wikipedia, how could I know that I am getting fresh data. I saw that las update was October / November 2010. When is going to be the next one? I also would like to know if there is some other service like the one mentioned before. I also looked to Freebase, but I think DBpedia is a good choice.
The cycles in which DBpedia datasets are released vary somewhat. It is approximately twice a year. The last release (3.6) was in January 2011, using the Wikipedia dumps from October/November 2010 because Wikimedia had problems producing new dumps at the time.
The next release (3.7) is probably going to be in August 2011.
