“work” given as predicate for “what did terry pratchett write?”

[progval]

It should not be a predicate (neither should “works”), because it does not make sense (and is an alias for “occupation” on Wikidata).

And also, there is a regression because it used to be (?, author, Terry Pratchett)

[Ezibenroc]

(?, author, Terry Pratchett) is a subset of what we returns, since author is in the inverse predicate. There is no regression.

But I agree to remove work and works.

I put them because they are properties used by wikidata to provide the books of an author (see http://www.wikidata.org/wiki/Property:P800 and http://www.wikidata.org/wiki/Q3335) but I will remove them if they are ambiguous.

Yes, it would be nice to display the reverse predicates too on the UI

[Ezibenroc]

We could use notable works instead.

The Wikidata module does not support reverse-predicates, so the Platypus is broken on these searches :(

[yhamoudi]

I think it's the only query that appears in https://github.com/ProjetPP/PPP-WebUI/blob/master/questions.js and that cannot work without reverse predicates. We should remove it temporarily.

so the Platypus is broken on these searches :(

yes it's sad, but we cannot hardcode this question into the question parsing module. I let you lobby @Tpt so that reverse predicates are supported quickly by the wikidata module :)

[Tpt]

Support of reverse predicate is currently bocked by the fact that we need to be able to do fast queries (thing that WikidataQuery doesn't allow). I've nearly finished to implement queries into my custom EntityStore. The remaining things are to create indexes in the deployed database and to convert Wikidata module to use the EntityStore instead of Wikidata query.

So, if everything goes well (I'm not sure that MongoDB will be reactive enough with thousands of indexes) Wikidata module should be able to support reverse predicates within two weeks.

But if you want these things to go quicker, contributions are welcome!

In the meantime, I reverted the version of the Grammatical used by the Platypus to 0.6.1.

If it's just for "what did terry pratchett write?", we lose more questions that what we win...

[progval]

It's not just for Terry Pratchett
