ORES/nl

ORES (/ɔɹz/) is een webservice en API voor machinaal leren as a service voor Wikimedia-projecten die onderhouden wordt door het Scoring Platform team. Het systeem is ontworpen om te helpen bij het automatiseren van belangrijk wiki-werk, zoals het onderkennen van vandalisme en het verwijderen ervan. In mei 2019 kent ORES scores toe aan de kwaliteit van bewerkingen en van artikelen.

ORES is een dienst die op de achtergrond werkt en biedt niet geen directe mogelijkheid om gebruik te maken van deze resultaten. Als je gebruik wilt maken van de uitkomsten van ORES, kijk dan naar deze lijst van tools die ORES-scores gebruiken. Als ORES jouw wiki nog niet ondersteunt, kijk dan naar onze instructies om ondersteuning in te schakelen.

Kwaliteit van bewerkingen
One of the most critical concerns about Wikimedia's open projects is the review of potentially damaging contributions ("edits"). There's also the need to identify good-faith contributors (who may be inadvertently causing damage) and offer them support. These models are intended to make the work of filtering through the Special:RecentChanges feed easier. We offer two levels of support for edit quality prediction models: basic and advanced.

Basic support
Assuming that most damaging edits will be reverted and edits that are not damaging will not be, we can build using the history of edits (and reverted edits) from a wiki. This model is easy to set up, but it suffers from the problem that many edits are reverted for reasons other than damage and vandalism. To help that, we create a model based on bad words.


 * – predicts whether an edit will eventually be reverted

Advanced support
Rather than assuming, we can ask editors to train ORES which edits are in-fact  and which edits look like they were saved in. This requires additional work on the part of volunteers in the community, but it affords a more accurate and nuanced prediction with regards to the quality of an edit. Many tools will only function when advanced support is available for a target wiki.


 * – predicts whether or not an edit causes damage
 * – predicts whether an edit was saved in good-faith

Article quality
The quality of Wikipedia articles is a core concern for Wikipedians. New pages must be reviewed and curated to ensure that spam, vandalism, and attack articles do not remain in the wiki. For articles that survive the initial curation, some of the Wikipedians periodically evaluate the quality of articles, but this is highly labor intensive and the assessments are often out of date.

Curation support
The faster that seriously problematic types of draft articles are removed, the better. Curating new page creations can be a lot of work. Like the problem of counter-vandalism in edits, machine predictions can help curators focus on the most problematic new pages first. Based on comments left by admins when they delete pages (see the logging table), we can train a model to predict which pages will need quick deletion. See en:WP:CSD for a list of quick deletion reasons for English Wikipedia. For the English model, we used G3 "vandalism", G10 "attack", and G11 "spam".


 * – predicts if the article will need to be speedy deleted (spam, vandalism, attack, or OK)

Assessment scale support
For articles that survive the initial curation, some of the large Wikipedias periodically evaluate the quality of articles using a scale that roughly corresponds to the English Wikipedia 1.0 assessment rating scale ("articlequality"). Having these assessments is very useful because it helps us gauge our progress and identify missed opportunities (e.g., popular articles that are low quality). However, keeping these assessments up to date is challenging, so coverage is inconsistent. This is where the  machine learning model comes in handy. By training a model to replicate the article quality assessments that humans perform, we can automatically assess every article and every revision with a computer. This model has been used to help WikiProjects triage re-assessment work and to explore the editing dynamics that lead to article quality improvements.

The articlequality model bases its predictions on structural characteristics of the article. E.g. How many sections are there? Is there an infobox? How many references? And do the references use a cite template? The articlequality model doesn't evaluate the quality of the writing or whether or not there's a tone problem (e.g. a point of view being pushed). However, many of the structural characteristics of articles seem to correlate strongly with good writing and tone, so the models work very well in practice.


 * – predicts the (Wikipedia 1.0-like) assessment class of an article or draft

Support table
The following table reports the status of ORES support by wiki and model available. If you don't see your wiki listed, or support for the model you'd like to use, you can request support.

API usage
ORES offers a Restful API service for dynamically retrieving scoring information about revisions. See https://ores.wikimedia.org for more information on how to use the API.

If you're querying the service about a large number of revisions, it's recommended to batch 50 revisions in each request as described below. It's acceptable to use up to 4 parallel requests. For even larger number of queries, you can run ORES locally

Example query: |wp10&revids=34854345|485104318 http://ores.wmflabs.org/v3/scores/enwiki/?modelsdraftquality|wp10&revids34854345|485104318
