Bot for RKD professions

Was wondering if the bot to add the RKD professions is still active? We are depended on this bot to filter on photographers etc. https://www.wikidata.org/w/index.php?title=Q42424648&action=history --Hannolans (talk) 12:12, 16 November 2017 (UTC)

Die zou wel elke nacht moeten draaien, maar ik vroeg me zelf laatst ook al af of er iets mis was. Net even gekeken. De job is op 20 oktober vastgelopen en er is sindsdien geen nieuwe job gestart omdat de oude nog in de weg zat. Afgeschoten en een nieuwe opgestart. Robot doet het weer. Bedankt voor je berichtje. Ik ga nog eens kijken hoe ik een maximale runtime kan meegeven of iets anders om dit te voorkomen. Multichill (talk) 20:42, 16 November 2017 (UTC)

Wikidata Property Suggester database weird numbers?

Hi Multichill,

We were chatting at WikidataCon about the use of the Property Suggester database for the Recoin tool, I very much liked that suggestion and we are trying to implement that now.

We encountered some mismatches between our frequency calculation and the one in the database though, I wanted to ask whether you have an idea what could be the reason between the following mismatch:

In the property suggester database, it says that only 77 automobile model (Q3231690) have length (P2043), and it says that these are 1%:

 SELECT * FROM wikidatawiki_p.wbs_propertypairs WHERE pid1=31 and qid1=3231690 order by probability desc 

([Query ])

Yet when I go to the SPARQL endpoint I get 3266 such occurrences (out of 8240 in total, i.e., 39%) using the following query:

 SELECT (count(distinct ?item) as ?cnt)
 WHERE 
 {
   ?item wdt:P31 wd:Q3231690.
   ?item wdt:P2043 ?val.
 }

Do you have an idea what might be the reason? Are we misinterpreting the Property Suggester data in some way?

Note that the property suggester database is not live and mostly updated once per month. Sjoerd de Bruin (talk) 16:35, 27 November 2017 (UTC)
Ah, that might explain the discrepancy. I'll check in the next update. Thanks! Ls1g (talk) 09:25, 29 November 2017 (UTC)
