Improved property recommender for Wikidata
Open, Stalled, Needs TriagePublic


Build an AI that suggest property sets for Wikidata item based on instance of/subclass of and other statements.

What it does:

  • If the item is instanceof human, suggest 10 most frequently used properties for humans
  • If the item has occupation "actor", suggest properties about actors such as awards, films, etc.

Wiki thing it helps with:

  • Help avoid human error, choice of wrong properties
  • Have more complete items, stimulate people to complete data sets for items

Things that might helps us get this thing built:

  • Featured or "complete" items
  • Item "completeness" estimation (there's a project doing that IIRC)

We already to have an existing recommender system. It should be improved. It is very important for me that we do not hard-code classes for the recommendation.

Great. I figured that was the case. What would be the best way to understand how prediction already works and to find out where improvements could be made?

@Lydia_Pintscher, is this the docs for the current recommender?


If work on this is started let's talk about it first.

@Lydia_Pintscher just showed me and apparently there's also a gadget for recommending properties from the same group.

FYI, I talked to @Sjoerddebruin about this at WikiCite and he showed me I think that we should consider this when trying to make improvements.

I wonder if blaze graph this. @Smalyshev, how familiar are you with the property suggestion system and if blaze graph might be a good solution for recommend properties for entities (items, properties themselves)?

@Halfak depends on whether we can make a query that is fast enough. I think @Jonas did some work on that and for some cases queries are fast, while for others they are rather slow and it would better work as pre-calculated data set.
