Ekstensi:ORES
Ekstensi ORES mengintegrasikan data dari layanan ORES ke dalam tampilan Perubahan Terbaru.
Untuk saat ini, layanan sisi belakang ORES hanya diatur untuk wiki Wikimedia, dan terdapat banyak yang perlu dikerjakan untuk memasangnya di instalasi MediaWiki pihak ketiga.
It is installed on several Wikimedia sites, but no longer deployed to new ones. For newer work on machine learning in Wikimedia, see Machine Learning/Modernization.

Pemasangan
- Unduh dan letakkan berkas-berkasnya di dalam sebuah direktori yang bernama
ORESdi folderextensions/Anda.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/ORES - Tambahkan kode berikut di bagian bawah LocalSettings.php Anda:
wfLoadExtension( 'ORES' );
Selesai – Telusuri ke Special:Version di wiki Anda untuk memastikan ekstensinya berhasil dipasang.
Anda perlu menjalankan skrip pemeliharaan CheckModelVersions.php begitu ekstensinya telah diedarkan (dan setelah itu Anda juga bisa menjalankan PopulateDatabase.php)
If you want to setup a local development environment for MediaWiki + ORES extension using the following ORES extension local development guide:
Variabel konfigurasi
Berikut adalah variabel-variabel konfigurasi dan nilai-nilai baku mereka dan sedikit keterangan tentang mereka.
// URL of the ORES service
$wgOresBaseUrl = 'https://ores.wikimedia.org/';
// Either to exclude edits made by bot to score
$wgOresExcludeBots = true;
// Models to score
$wgOresModels = [
'damaging' => [ 'enabled' => true ],
'goodfaith' => [ 'enabled' => true ],
'reverted' => [ 'enabled' => false ],
'articlequality' => [
'enabled' => false,
'namespaces' => [ 0 ],
'cleanParent' => true,
'keepForever'=> true
],
'wp10' => [
'enabled' => false,
'namespaces' => [ 0 ],
'cleanParent' => true,
'keepForever'=> true
],
'draftquality' => [
'enabled' => false,
'namespaces' => [ 0 ],
'types' => [ 1 ],
],
];
// Will replace ORES with Lift Wing for fetching scores
$wgOresUseLiftwing = false;
// URL for Lift Wing - Skippeed if null
$wgOresLiftWingBaseUrl = null;
// Thresholds of different sensitivies in ORES
$wgOresDamagingThresholds = [ 'soft' => 0.7, 'hard' => 0.5 ];
// Namespaces the ORES should score. Empty array means all namespaces.
// If not empty, it will only works on the given namespaces.
// Determine namespaces like [ 0 => true, 120 => true ].
$wgOresEnabledNamespaces = [];
// Database id for ORES service. If not determined, it'll use database name.
// You can choose 'testwiki' that ORES service sends last two digits of rev_id flipped.
// For example: https://ores.wikimedia.org/v1/scores/testwiki/damaging/12345
$wgOresWikiId = null;
Debugging an ORES extension deployment
After we deploy the extension with either ORES or Lift Wing as a backend we can use the steps in the ORES extension debugging guide to make sure it is working fine.
Respons layanan ORES
ORES extension is merely more than an interface to the ORES service. The service returns a probability score of edits being damaging like this (API v1):
{
"724030089": {
"damaging": {
"prediction": false,
"probability": {
"false": 0.8917716518085119,
"true": 0.10822834819148802
}
}
}
}
It means this edit (diff=724030089) is 10% likely to have caused damage. Note that 90% likely doesn't mean 9 out of ten cases will be vandalism. Choosing thresholds should be done via analysing recall (percentage of vandalism it can catch) or false positive rate. In ORES the "soft" threshold is when recall is 75% (meaning it will include 75% of all damaging edits) and the "hard" threshold is when recall is 90%. You can get the thresholds from model info (an example).
Skema basis data
ORES extension introduces two new tables: ores_model and ores_classification. See the full database schema description.
Aliran kerja ekstensi
Skor
Once an edit is made the extension triggers a job to hit the service and store the results in the ores_classification table. It means it will not include scores for edits made before the deployment. In order to fill the database you can run the maintenance script PopulateDatabase.php. It will hits the service and keeps the score for the last 5,000 edits. You can run it several times if needed.
Once a model gets updated to a newer version CheckModelVersions.php maintenance script needs to be ran to update the ores_model table which will cause to scores stored in the ores_classification table become deprecated. You can clean these obsolete scores by running PurgeScoreCache.php maintenance script.
Antarmuka
The extension won't show anything when deployed but it will add itself as a beta feature (Ekstensi:BetaFeatures is a dependency of this extension) and once it's enabled by the user it will use hooks in ChangesList (RecentChanges, Watchlist, and RelatedChanges) in both old and enhanced mode and highlights when score exceeds the given threshold.
