Hey wiki-research-l folks,
Gerard didn't actually link you to the quality criteria he takes issue with. See https://www.wikidata.org/wiki/Wikidata:Item_quality I think Gerard's argument basically boils down to Wikidata != Wikipedia, but it's unclear how that is relevant to the goal of measuring the quality of items. This is something I've been talking to Lydia about for a long time. It's been great for the few Wikis where we have models deployed in ORES[1] (English, French, and Russian Wikipedia). So we'd like to have the same for Wikidata. As Lydia said, we do all sorts of fascinating things with a model like this. Honestly, I think the criteria is coming together quite nicely and we're just starting a pilot labeling campaign to work through a set of issues before starting the primary labeling drive.

Hoi, What I have read is that it will be individual items that are graded. That is not what helps you determine what items are lacking in something. When you want to determine if something is lacking you need a relational approach. When you approach a award like this one [1], it was added to make the award for a person [2] more complete. No real importance is given to this award, just a few more people were added because they are part of a group that gets more attention from me [3]. For yet another award [4], I added all the people who received the award because I was told by someone's expert opinion that they were all notable (in the Wikipedia sense of the word). I added several of these people in Wikidata. Arguably, the Wikidata the quality for the item for the award is great but it has no article associated to it in Wikipedia but that has nothing to do with the quality of the information it provides. It is easy and obvious to recognise in one level deeper that quality issues arise; the info for several people is meagre at best.You cannot deny their relevance though; removing them destroys the quality for the award.
The point is that in relations you can describe quality, in the grading that is proposed there is nothing really that is actionable.
When you add links to the mix, these same links have no bearing on the quality of the Wikidata item. Why would it? Links only become interesting when you compare the statements in Wikidata with the links to other articles in the same Wikipedia. This is not what this approach brings.
Really, how will the grades to items make a difference. How will it help us understand that "items relating to railroads are lacking"? It does not.
When you want to have indicators for quality; here is one.. an author (and its subclasses) should have a VIAF identifier. An artist with objects in the Getty Museum should have an ULAN number. The lack of such information is actionable. The number of interwiki links is not, the number of statements are not and even references are not that convincing. Thanks, GerardM

Gerard, the outcome will be very actionable. We will have the groundwork needed to identify individual items and sets of items that need improvement. If it for example turns out that our items related to railroads are particularly lacking then that is something we can concentrate on if we so chose. We can do editathons, data partnerships, quality drives and and and.
