What happens?:

  • Some of the edges do not have an edge label.

What should have happened instead?:

  • All of the edges should have an edge label. The table view displays the result correctly.

Software version (skip for WMF-hosted wikis like Wikipedia):
Not sure how to best see that on Wikibase.cloud.

As a note: There is a similar task: https://phabricator.wikimedia.org/T261116 but in my case the order of the nodes and edgelabel is correct, - unless I am mistaken.

Interestingly, with LIMIT 154 it works. With LIMIT 155 it does not work.

LIMIT 154 doesnt seem to work for me, but LIMIT 100 does.
So it seems the behaviour of showing / how showing the labels inconsistent

And to visually aid folks.

Example of labels on edges (connections/arrows) not being shown

Yes. It seems not to be 154/155 necessarily. LIMIT 130 works for me currently.

I am not into the code, but the Wikidata Query Service code here seems quite innocuous: https://github.com/wikimedia/wikidata-query-gui/blob/master/wikibase/queryService/ui/resultBrowser/GraphResultBrowser.js#L218

Have you ever noticed a similar issue on wikidata.org or if this is just on wikibase.cloud?

Fnielsen added a comment.Feb 23 2024, 6:28 PM

@Tarrow No, but I have not checked.

I have tried introducing LIMIT and strangely labels appear for LIMIT 136 but not for LIMIT 137.

We were able to reproduce this on wikidata:

#Asterophryinae parent taxon reverse graph
#defaultView:Graph
PREFIX gas: <http://www.bigdata.com/rdf/gas#>

SELECT ?item ?itemLabel ?pic ?linkTo (?relation AS ?edgeLabel)
WHERE
{
  BIND("someedgeLabel" AS ?relation)
  SERVICE gas:service {
    gas:program gas:gasClass "com.bigdata.rdf.graph.analytics.SSSP" ;
                gas:in wd:Q1968598;
                gas:traversalDirection "Reverse" ;
                gas:out ?item ;
                gas:out1 ?depth ;
                gas:maxIterations 3 ;
                gas:linkType wdt:P171 .
  }
  OPTIONAL { ?item wdt:P171 ?linkTo }
  OPTIONAL { ?item wdt:P18 ?pic }
  SERVICE wikibase:label {bd:serviceParam wikibase:language "en" }
} LIMIT 200

shows no edgeLabels but

#Asterophryinae parent taxon reverse graph
#defaultView:Graph
PREFIX gas: <http://www.bigdata.com/rdf/gas#>

SELECT ?item ?itemLabel ?pic ?linkTo (?relation AS ?edgeLabel)
WHERE
{
  BIND("someedgeLabel" AS ?relation)
  SERVICE gas:service {
    gas:program gas:gasClass "com.bigdata.rdf.graph.analytics.SSSP" ;
                gas:in wd:Q1968598;
                gas:traversalDirection "Reverse" ;
                gas:out ?item ;
                gas:out1 ?depth ;
                gas:maxIterations 3 ;
                gas:linkType wdt:P171 .
  }
  OPTIONAL { ?item wdt:P171 ?linkTo }
  OPTIONAL { ?item wdt:P18 ?pic }
  SERVICE wikibase:label {bd:serviceParam wikibase:language "en" }
} LIMIT 100

does show them on my machine. I guess this is not therefore a wikibase cloud specific bug and should probably be looked at by Wikibase Product Platform Team WPP so I'll ping @Ifrahkhanyaree_WMDE
