James said: See https://en.wikipedia.org/wiki/Wikipedia:Labels/Edit_quality We're almost ready to train and deploy a model with some nuance in it's prediction based on the *reason* that something should be reverted. (E.g. damaging/not-damaging and good-faith/bad-faith) We already have the labeling campaign done for Portuguese Wikipedia and we're nearly done for Turkish, Persian and English. Beyond that work, I think there's a fun clustering project to be done here to discover categories of revert reasons. I'm always looking for collaborators to advise on these types of fun projects. *hint hint* But really, getting back to what I think Jane was referring to: we're not just building revert predictors. We're also building article quality models (e.g. http://ores.wmflabs.org/scores/enwiki/wp10/674383487/ -- The most recent edit of the article "Waffle" is probably of Feature Article quality) and edit type classifiers. See https://meta.wikimedia.org/wiki/Research:Automated_classification_of_edit_t… So, you'll be able to look at how many article edits were "Information-Insertion/Modification" and how many were just "Copyedit" in X-tools or Special:UserContributions (assuming someone uses our service to implement that) But when it comes down to it, I think our best measures of value-added won't be the output of a machine classifier, but rather some careful work in measurement theory. As Pine hopes ("assigning value to edits or editors; I would still like that project to go forward."), the project is continuing to move forward -- just slower than I had planned. Due to the massive interest in Revision Scoring, I've been putting a lot more of my time there recently. Again, I'm always looking for collaborators on these projects. I do as much work as I can to get them online and I have a small team working with me, but we can always use a hand. There are lots of ways to contribute. You don't need to code. We need help labeling edits, doing outreach in new wikis that we'd like to support and translating our software and docs. -Aaron On Tue, Aug 4, 2015 at 7:53 AM, James Salsman <jsalsman(a)gmail.com> wrote:
