Abstract (at least 300 words to describe your proposal)

How well Editors work together has been a key question since the inception of the encyclopedia. When we also consider the twin question - how articles improve depending on who edits them - our problem becomes similar to the Macroeconomics Field which considers the performance of Countries and their Exports. Borrowing from new developments in Macroeconomics, we reuse a technique which scores Editors by the quality of their edited-articles portfolio. Conversely we score Articles by the quality of their contributing editor portfolio. The method is a two node-type version of the Google pageRank algorithm. Then we also establish the "ground-truth" of editor investment and article development. For editors our ground-truth is "Labour Hours", which is derived from the editors contribution history. For articles our ground-truth is a mix 5 measures of articles text (citations per sentence, number of images, etc.)

We tune two variables in the model called α and β, which determine the ”importance” of the high quality articles in an editor's portfolio, and highly invested editors in an article's contribution history. Both α and β are optimized to maximize the ranking correlations of editors (upto 0.75 corellation) and articles (upto 0.91 corellation) between the model and groundtruth metrics. We find the correllations for 12 categories on Wikipedia. By finding the optimizing values of α and β we know how characterized a category is by highly invested editors, or by highly developed articles.

To get an intuition for the method consider these find telling extremes. The best editors in Category:Military history of the US - a category known for being very competitive - are characterized by emphasizing investment in touching many articles in the category. On the other end, the editors in Category:Sexual acts - a taboo subject where much editing could be considered perverse - are characterized by divesting in touching many articles in the category.
