Thanks both! This clarifies a lot. I think the primary issue that editors had raised and I had hoped to explore was popularity/importance v. obscurity.
Specifically, there have been concerns that the results tilt towards more popular articles (here <https://www.mediawiki.org/wiki/Topic:Swjyfj59pkjfol7m> and here <https://www.mediawiki.org/wiki/Topic:Sxy84nxinxqqld2i>), but it seems that page traffic is not a variable. Instead, what seems to be happening is that the raw # of similar terms is being used, rather than the % of similar terms. This means that longer articles are favored. Is that a fair assessment? -J On Thu, Feb 18, 2016 at 4:15 PM, Gergo Tisza <gti...@wikimedia.org> wrote: > On Thu, Feb 18, 2016 at 4:00 PM, Jon Katz <jk...@wikimedia.org> wrote: > >> Can someone on this list point me to where the more-like code sits?
