Cross-Pollinating DBpedia and FreebaseNow that Freebase is available as Linked Data a big question that comes to mind is whether these two major projects will move to assimilate one another. DBpedia and Freebase – two endeavors primarily focused on curating unstructured and semi-structured data about everything and releasing it back into the wild (with structure) – get the bulk of their information from Wikipedia, so the amount of topical overlap is assumed to be extremely high. DBpedia gains new information when it extracts data from the latest Wikipedia dump, whereas Freebase, in addition to Wikipedia extractions, gains new information through its userbase of editors.

It is this incredible amount of overlap (with regard to content and purpose) which creates a sort of paradox, where it can be speculated that DBpedia and Freebase would both gain and lose value through efforts to cross-pollinate. Assimilating each other's updates would cause both to become "more complete" (in the same sense that an incrementing number is closer to infinity after each increment), thus gaining value. However, both may lose value as well if "value" is the perception of being "the most complete database about everything." Freebase may see a drop in userbase growth and participation if it becomes a mirror of DBpedia (or vice-versa) and the popularity once garnered by one project may shift towards the other, or away entirely.

This may not be an actual paradox since we're talking about mixing two different perceptions of value (value from the developer's point of view and value from the point of view of the project itself), but we must still look at it from both vantage points. This may simply be another issue of business interest vs. developer interest. All issues regarding popularity and ubiquity aside, cross-pollination is a Good Thing for the purposes of the Semantic Web and Linked Data in general.
