NOTE: T296814 must be done before this
User story
As a user, I want to be able to get an image suggestion (with a confidence score) for a particular image id.
As a developer, I want to be able to store suggested image data with confidence scores.
To make this possible I need to
a) have appropriate data in the commonswiki search index (T296814 and related tasks)
b) configure commons media search to make use of the new data (this ticket)
Once we have the commons search index weighted_tags field populated with data from wikidata, we need to enable searching for images via wikidata ids. The following will need to be added to commons config
$wgMediaInfoCustomMatchFeature = [ 'depicts_or_linked_from' => [ 'fields' => [ 'statement_keywords' => [ [ 'prefix' => 'P180=', 'boost' => 0.06800689749434177 ], //depicts [ 'prefix' => 'P6243=', 'boost' => 0.0001 ], // digital representation of (arbitrary small value) ], 'weighted_tags' => [ [ 'prefix' => 'image.linked.from.wikidata.p18/', 'boost' => 0.9862993091599952 ], [ 'prefix' => 'image.linked.from.wikidata.p373/', 'boost' => 7.190793838918551 ], [ 'prefix' => 'image.linked.from.wikidata.sitelink/', 'boost' => 5.031161363459293 ], ], ], // logistic function 'functionScore' => [ 'scriptCode' => '100 / ( 1 + exp( -1 * ( _score + intercept ) ) )', 'params' => [ 'intercept' => -1.3459675572537635 ], ] ], ];
When this is in place, users will be able to search for, for example, images of cats using custommatch:depicts_or_linked_from=Q146
