ListeriaBot

ListeriaBot is a Wiki bot to automatically execute (simple) SPARQL queries to build Wikipedia tables on project pages to support e.g. edit-a-thons.

To prepare an edit-a-thon, it helps a lot to build a proactive list of subjects related to the theme, for which Wikidata items, Wikipedia pages, and Wikimedia Commons media files are created or amended. Using ListeriaBot one can automatically build a list of blue and red links in a table. Red links are pages that do not exist, and can be easily created by one click of the mouse. Blue links are articles that can be extended or enhanced. Participants can easily choose their page to write according to their interest. Also, the number of existing Wikipedia pages in other languages can be easily indicated. As well as an image (P18). You can execute the same query on multiple language Wikipedia's, to get the list specific to the language. Then you can put the link to the Wikipedia project page on the Wikidata WikiProject item page. Doing so all major Wikimedia platforms (Wikipedia, Wikidata, and Wikimedia Commons) are interlinked.

Setting up a project

Please also create a Campaign dashboard, so you get automatic statistics about the user activity.

Doing so, you get an integrated project environment, interlinking all involved platforms.

Techniques

• Analyse your theme, and search for example pages (title + a number of core properties).
• Create a WikiProject in Wikidata; example.
• Use Excel or Google Spreadsheets to compile a subject list.
• Use OpenRefine, link all the objects to the WikiProject by using e.g. Maintained by WikiProject (P6104).
• You could use as well Pywikibot pwb add_statement or QuickStatements.
• What Links Here (Wikidata)
• Build a Wikidata query.
• Copy the query into a {{Wikidata list}} on a project page.
• Save the page.
• Execute the query once manually.
• Verify the results.
• Correct any errors, in the script, and in the data.
• The ListeriaBot runs at regular times, once additional data is available.
• Create a Wikimedia Commons Category + {{Wikidata Infobox}}.

Wiki code examples

Here is a real example. You can just copy-paste the Wiki code in a project page:

Lijst van artikelen die kunnen worden aangemaakt, of aangepast, tijdens de schrijfsessie in het kader van [[../../../|Bouwfirma Serck nv]].

* [[wikidata:Special:WhatLinksHere/Q114422535|Wikidata lijst]]

{{Wikidata list|sparql=# Select all items for this project
SELECT ?item ?linkcount WHERE {
  ?item wdt:P6104 wd:Q114422535;
    wikibase:sitelinks ?linkcount;
    wdt:P31 wd:Q5.
}
|columns=P18,item,label:naam,P735,P734,alias/nl:alias,description:beschrijving,P937:werklocatie,P19,P20,P569:geboren,P570:gestorven,P27:nationaliteit,P101,P106,P108,P800,P39,P166,P103,?linkcount:pages,P21:gender,P990:stem
|min_section=1
|sort=label
|links=red
|thumb=90
|autolist=fallback
|summary=itemnumber
}}
{{Wikidata list end}}

Known problems

Automatic execution does not work

• Maybe there is a syntax error.
• Verify the history of the Wikipedia page.
• Try to run the job manually (should provide OK status).

Delay in execution

It is not always clear why there is a delay in execution. Machine capacity? Technical reasons?

• Try to run the job manually

Bad Gateway

Seems to frequently occur.

• https://github.com/magnusmanske/listeria_rs/issues/97
• phab:T324882

Content of pages possibly not updated.

Updated table not visible for not logged-in users

• Perform a cache refresh

Killed by OS for overloading memory

The query is possibly too complex.

Maybe the content of page was still updated.

Field 'message' doesn't have a default value

Reason unknown.
