Yes, I was thinking of this when making this proposal. The thing is that 
"is a list of" is not a very powerful way to describe lists. It can only 
do very simple things. Examples like the "list of inventors killed by 
their own invention", which are easy to do in SPARQL, are not possible 
there.


I should add that there are also problems with having arbitrary SPARQL 
queries. They are on the other end of the sprectrum from where "is a 
list of" is: they can express too much details (sorting order, label 
recall, query optimiser settings, etc.). When using SPARQL for list 
descriptions, the community should try to use the simplest query 
possible without any extras for formatting and sorting, or it will again 
be hard to use this.

It would be relatively easy to continuously harvest data from Wikipedias
based on such categories.

This also applies to a huge number of Wikipedia categories (the non

describing them attached to the Wikidata items for the categories.

Might be nice, but we need a good way to present the query in the UI
(see below).

I think it may be a good idea to start thinking about some way of
storing queries on Wikidata maybe? On one hand, they are just
strings,
on the other hand, they are code - like CSS or Javascript - and
storing
them just as strings may be inconvenient. Maybe .sparql file
extension
handler like we have for .js and .json and so on?

Hoi,
For many categories we have exactly that in Reasonator. This functionality
is based on "is a list of". It functions not for all categories or all
content for a category. Wikidata often shows more data particularly when
the categories from "other" Wikipedias have been harvested.

It would be relatively easy to continuously harvest data from Wikipedias
based on such categories.

would that imply creating a new data type? This idea could be implemented
today with direct links to WDQS but storing the SPARQL query in clear as a
property value and using a URI formatter to point to the corresponding
services sounds like the right approach.

[Wikidata] ORES review tool default sensitivity changed now

2016-08-24 Thread Amir Ladsgroup 
Hey all,
We just deployed a change that changed default sensitivity of ORES review
tool from "hard" to "soft" (meaning recall would drop from 0.9 to 0.75 but
percentage of false positives drops too). You are still able to change it
back in your preferences (Recent changes tab).

Please come to us for any issues or questions.

This also applies to a huge number of Wikipedia categories (the non
subjective ones). It would be extremely useful to have queries describing
them attached to the Wikidata items for the categories.
