Many Wikipedia articles contain facts and connections to other articles that are not easily understood by a computer, like the population of a country or the place of birth of an actor. In Wikidata you will be able to enter that information in a way that makes it processable by the computer. This means that the machine can provide it in different languages, use it to create overviews of such data, like lists or charts, or answer questions that can hardly be answered automatically today.
Because I had some questions not addressed in the Wikidata pages that I saw, I went onto the Wikidata IRC chat (http://webchat.freenode.net/?channels=#wikimedia-wikidata) where Denny_WMDE answered some questions for me.
hi. I’m very interested in wikidata and am trying to write a brief blog post, and have a n00b question.
When there’s disagreement about a fact, will there be a discussion page where the differences can be worked through in public?
1. there will be a discussion page, yes
2. every fact can always have references accompanying it. so it is not about “does berlin really have 3.5 mio people” but about “does source X say that berlin has 3.5 mio people”
wikidata is not about truth
but about referenceable facts
When I asked which fact would make it into an article’s info box when the facts are contested, Denny_WMDE replied that they’re working on this, and will post a proposal for discussion.
So, on the one hand, Wikidata is further commoditizing facts: making them easier and thus less expensive to find and “consume.” Historically, this is a good thing. Literacy did this. Tables of logarithms did it. Almanacs did it. Wikipedia has commoditized a level of knowledge one up from facts. Now Wikidata is doing it for facts in a way that not only will make them easy to look up, but will enable them to serve as data in computational quests, such as finding every city with a population of at least 100,000 that has an average temperature below 60F.
On the other hand, because Wikidata is doing this commoditizing in a networked space, its facts are themselves links — “referenceable facts” are both facts that can be referenced, and simultaneously facts that come with links to their own references. This is what Too Big to Know calls “networked facts.” Those references serve at least three purposes: 1. They let us judge the reliability of the fact. 2. They give us a pointer out into the endless web of facts and references. 3. They remind us that facts are not where the human responsibility for truth ends.
