User:Isaac (WMF)/article quality

What?
Display the predicted quality of Wikipedia articles based on the quality model from a simple language-agnostic quality model and a recommendation for what to improve based on the lowest-scoring feature.

How?
This script does not depend on any external APIs. It gathers several article features -- page length, links, references, categories, media, sections -- directly from the article HTML when an article is viewed and then transforms them into quality scores using hard-coded thresholds/weights that were learned as part of the model mentioned above.

To install, simply go to Special:MyPage/common.js for just English and put  or.

The script will run automatically when viewing any English Wikipedia article and display the score next to the article title. The script could be easily extended to any other language using the language-specific feature thresholds in this file.
