Grants:IEG/Revision scoring as a service/Renewal

From Meta, a Wikimedia project coordination wiki

This project is requesting a 6-month renewal of the grant, to continue work in the areas described below.


In this 6 month extension, we'll extend our service to Wikimedia communities by extending our system in three ways:

  • We'll add prediction models in for Wikipedia 1.0 assessment ratings[1]
  • We'll add a prediction model for edit type classification [2]
  • Wiki labels UI extensions -- we'll Wikipedians to create and administrate their own campaigns [3]

There are also 3rd party developers who are working to extend AI to solve other problems in Wikimedia projects. We'll be spending substantial time and energy supporting their projects. Here are the project we know about thus far:

Finally, another key outcome of this grant period will be a plan for the long term sustainability of this project. IEG funding has gotten this project off the ground, but it's time to level up and find a home. We'll be exploring many directions including Wikimedia Foundation engineering (e.g. the mw:Services), mw:Research and Data and product teams like mw:Collaboration. We've also managed to fund one of our major contributors through en:Wikimedia Deutschland, so we'll be talking to them about extended support if our work on Wikidata is successful. By the end of this 6 month period, we plan to have a plan! In the meantime, we'll be making the value and needs of our project clear to these parties.


For hardware cost calculations, digital ocean prices were used as basis. We use Wikimedia Labs instead to circumvent these costs. Also note that we intend to increase our hardware usage based on user demand using labs.

  • Yuvipanda/YuviPanda (WMF) will continue to assist the project with maintenance & performance improvement as a part of volunteer and his WMF staff time

  • We intend to hire two or more contractors/grantees and divide this between them as their schedules permit.

We have came a long way since the start of our project. We feel we have a significant room of improvement even beyond our goals of the past six months. Everything we are hearing suggests that there is demand for our work. We don't want to lose momentum and we want to implement focus on implementing the features that seem to be in highest demand (which we have listed above).

Measures of success[edit]

Adoption rate
We will instrument logging in the API service in order to track how many scores are requested. Success means gathering wide adoption. It could be that a single tool uses our scores heavily or that many tools use the service lightly. The most important measure of our impact is how often our scores are *used* externally. We will instrument the funnel of score generation to know how many scores are requested/served and how fast our response is using statsd and graphite.
Supplementally, we'll also track the set of tools that use revision scoring as best we can using word of mouth and UserAgent processing. See our manually curated list. We'll be successful if we can either sign on a major tool (e.g. en:WP:Huggle) or double the number of lessor tools and analyses on the list by the end of 6 months.
New models
We will use standard model training and testing strategies to ensure the accuracy of new models for predicting article quality and edit types. New models will first be deployed for enwiki, but will later be deployed for other wikis as needed and where we can obtain liaison support.
System performance
We will perform analyses and improve system performance of the ORES service so that most requests are served from the cache (1000-10,000 times faster) and requests of 50 'reverted' scores will have a median response time of less than 6 seconds.


  1. e.g. we've already used this model to support WikiProject Medicine re-assessment triaging -- we'd like to host the model on ORES and build a simple self-serve UI.
  2. e.g. questions about edit types raised in the Visual Editor experiment and future interventions could be more easily answered. We're also working with researchers who would like to build editor expertise profiles who would like to use this service.
  3. Right now, starting new campaigns and doing administrative work requires access to the database. We'd like to extend the system to be used by any Wikipedia editor.

  • Support Support While many probably find it difficult to evaluate this project, since not enough time has passed for many end-user tools to adopt it, the underlying idea clearly holds promise and I think it should be granted the extension to allow it to grow to its potential.--Anders Feder (talk) 07:08, 5 July 2015 (UTC)
  • Support Support I totally support this project and the underlying goals behind it. It may seem like a lot of money, but I think it's a bargain at twice the price if the end product is something that is used by community members to gain better grip on editing behaviors while estimating quality at the same time.

  • Support Support Although accompany this project since a short time, already I noticed its fruits in my home wiki.I believe that its renewal is not only necessary, but also important for system expansion, thus offering more support to the wikis. --Leon saudanha (talk) 23:53, 5 July 2015 (UTC)
  • Support Support I am using this tool on pt-wiki. It is very usefull because vandalisms are labeled on my watch list. The renewal will support the tool improvement. I think that it is as great tool to fight against vandalisms on all wikis.Ixocactus (talk) 20:56, 6 July 2015 (UTC)
