What does ORES stand for?
ORES Stands for Objective Revision Evaluation Service

Predicting edit and article quality
ORES is an artificial intelligence service, which helps human editors improve the quality of edits and articles on Wikipedia. ORES uses a combination of open data and open source machine learning algorithms to train models and create scores that help predict the quality of edits as they are made. Learn more about the background and basics of ORES.

Tools and services that use ORES scores
Many tools use ORES scores. These tools automate time-consuming workflows that would otherwise be done manually by human editors.

ORES tools have been used to predict the quality of new edits and articles, quickly identify and address damaging edits (sometimes called "vandalism"), check for copyright violations, and patrol recent changes to articles.

What's an ORES score?
An ORES score is a score assigned to individual edits to articles on (Wikipedia). ORES scores help humans and machines describe the quality of an edit.

ORES scores allow humans and machines to generate better article content and to improve existing content.

ORES generates 2 types of scores “article” and “edit” “quality.

The “edit” ORES score helps to determine which edits are damaging to an article and which edits were made in good faith. This makes it easier to identify well intended folks who might need extra support to make better edits to articles. It can also help identify and revert clear incidents of vandalism.

What is a patroller?
ORES patrollers use specific filters to determine if new edits may be damaging. Potentially damaging edits are flagged and brought to the attention of human editors to make a final determination.

What are damaging edits (sometimes called "vandalism")?
The word "vandalism" implies an edit was made to create damage on purpose.

Sometimes folks make edits that have damaging effects, even if they make them with the best intentions. A patroller's job is to look for "damaging" edits, whether the damage was intended or not.

What is an article?
A wiki article is a webpage you can edit. The contents of an article change over time, so when ORES scores things about the article, we will either use the current article content, or historical content from an earlier edit.

What is an edit?
Wiki articles can be changed by anyone clicking on the "Edit" button, as explained on this help page. Each edit is made by one user, who opens the article, edits and saves. Edits cannot be changed after the fact, although you can make a new edit to correct mistakes.

When ORES scores an edit, we are analyzing the change to guess whether it was helpful or damaging to the article, and whether the change was made in good faith.

Edits are also known as "revisions". Reading the info page for an edit (example) will show you two things, the change made in that edit, and the contents of the article once that edit is applied.

What does quality mean?
Article content is scored using scales such as the Wikipedia 1.0 assessment, which are designed to give an idea of the completeness and readability of an article, as well as the richness of citations to supporting material. Each wiki language and project will use its own scale. See the English Wikipedia 1.0 scale for more information.

What is a model?
You can think of a model as a trained machine, which takes documents to be scored and outputs scores.

How do models get created?
Models are trained by the Scoring Platform staff, and uploaded to the server.

Getting help
Many folks who have a basic knowledge of how ORES works are interested in how to get help or how to help with ORES projects. A good place to start is the ORES support page. You can also look at our support table to see if we already support your Wiki.

How do I use ORES?
ORES is built into the RecentChanges, Watchlist, and Contributions pages for supported wikis. We recommend using the new filter interface, which gives more flexible searching and highlighting for several thresholds of damaging and good-faith prediction.

If your wiki isn't supported yet, please help us put together the language assets and let us know that you're interested in working with us to develop support. See "How to I get support for my wiki" above.

What tools are available that make use of ORES?
A number of tools are available that make use of ORES.

edit quality...?
There are three "edit quality" models, which each analyze changes to article content. The two advanced models try to predict whether the edit was damaging, and whether it was made in good faith.

The basic "reverted" model will try to predict whether the edit will be reverted, but this is problematic because it's based on which articles have already been reverted, which we suspect encodes some reviewer bias, and it also collapses a number of potential problems with the edit into a single outcome. Try to use the advanced models instead, if they are available for your wiki.

article quality...?
This model evaluates the entire article content, and gives it an overall quality score. This lets us evaluate the improvement in an article or set of articles over time, find high-quality articles, or find articles needing work. In English, the article quality model makes predictions using quality classes from the Wikipedia 1.0 scale.

For development?
The best place to start is to install MediaWiki-Vagrant, and enable the following roles: "betafeatures", "ores", "ores_service", and "wikilabels".

As a public service?
Nobody outside of the Scoring Platform group has tried this yet. Please contact the team directly for more support.

What deployments of ORES are there (WMFLabs & Production) and what's the difference between them?
We maintain a production-ish space where uptime and stability are optimized for as well as an experimental space where new models and features are deployed in a high-performance and flexible environment.

How is ORES configured?
ORES is configured via two respositories. The production-ish configuration lives in https://phabricator.wikimedia.org/source/ores-deploy/ and the experimental configuration lives in https://github.com/wiki-ai/ores-wmflabs-deploy. The primary configuration asset is config/00-main.yaml. Other configuration at the machine level comes from https://github.com/wikimedia/puppet.

What are my options when querying ORES?
ORES provides basic documentation about how to query the system using Swagger documentation. See https://ores.wikimedia.org for links to swagger documentation for each version of our API. For example https://ores.wikimedia.org/v2/ lists the documentation for the v2 interface.
