[Wikidata-bugs] [Maniphest] [Commented On] T157497: Engineer features for item quality model

[Halfak]

Halfak added a comment.

@Glorian_WD and I have been discussion how we'll get features that will give us some signal about which properties are expected for specific types of items. Here's my skeleton proposal:

1. query for most used statements (e.g. instance-of:human)
2. for the top N most used properties, query for the most secondary properties (instance-of:human, occupation:author)
3. for all items that pass some basic threshold of quality (e.g. has an external reference and >= N site-links) find the frequency of all other properties.
4. build an index on this so it can be quickly looked-up during scoring.
