DED added a comment to T260206: Add a link: testing API.

@MMiller_WMF correct me if I am wrong, but this Phab task encompasses a general test API that the research team can help with "until" someone can take over our code for productionalization. Just for the growth team to start building around it and know what to expect as output, start giving feedback, spot corner cases, etc. We created this task to clearly distinguish it from the work required to port the model into prod.

@kaldari The current model is ready, at least as a first iteration. I am in the process of handing over the code and have someone test it internally. @Niharika may know more about the specifics of the deployment responsibilities, is this something you can help with?
Also, we have the same constraints that @Ladsgroup brought up.

  • Talk pages are now included in the data.
  • I generate a new contribution graph. It's a bipartite of (users) and (wikipages/talkpages) with edit edges (weighted with the number of edits)
  • I tried multiple graph mining algorithms on the contribution graph to detect "sub-communities". So far, these techniques either didn't improve the performances, or the algos didn't scale to the data.

updates:

  • Tested a new model by adding concept-vectors and interaction graph.
  • The model is now slightly more difficult to interpret but achieves a better AUC (75%), using XGBoost.
  • Refactored the data preparation code in Scala. The code is much more scalable and can regenerate the necessary training data in 1 days on our analytics cluster.
  • Discussed with the product team the api endpoints and the potential env. for deployment (ORES ?)

updates:

  • I was finally able to process a large enough view of wikipedia history (from 2015 onwards). This should match with the SSO rollout to use the user_text as a unique id across wikis.
  • Transitioned to a new model based on word analysis to accommodate multiple wikis. I'll check what this is capable of. Basically, I gave up on sentiment analysis.

Hello @srijan. I didn't compute these metrics. Basically, processing only parts of enwiki creates an incomplete fingerprint for any user. Unless my current effort in making a pass on the full data succeeds, I plan on sampling users to obtain targeted full edit history.

  • First model is ready but with relatively low performance (~60% AUC). It was trained on a subset of the data in the english language. Calculating all-time edit diffs remains a challenge for such a large Wiki.
    • Ongoing work on tuning the model to improve the results.
