Hi Marco:
thank you for sharing your great work:
https://arxiv.org/pdf/2212.13104.pdf
I have kept pestering "big wigs" trying to make them understand the need and profit (if not monetary, definitely as common good) of exactly what you describe in your paper.

Hi Albretch,
given that Wikidata is far from being a complete source of knowledge https://arxiv.org/abs/2212.13104 about authors and their works and has very strict timeout rules,
you can try this basic query and start building from it. (Please notice that the wikibase:label service often leads to timeouts and a mitigation strategy may be retrieving labels in a separate step) :
SELECT DISTINCT ?authorLabel ?workLabel ?workPage ?authorPage WHERE { {?work wdt:P31 wd:Q7725634} UNION {?work wdt:P31 wd:Q47461344} . ### all instances of the type 'literary work' or 'written work' ?work wdt:P50 ?author . ### the association between works and their authors
SERVICE wikibase:label { bd:serviceParam wikibase:language "en". } ### the service for retrieving labels from Wikidata
?workPage schema:about ?work; schema:isPartOf https://en.wikipedia.org/. ### retrieve the wikipedia page of the work ?authorPage schema:about ?author; schema:isPartOf https://en.wikipedia.org/. ### retrieve the wikipedia page of the author
} limit 10

The query builder will make it a bit easier: https://query.wikidata.org/querybuilder/?uselang=en It will still be a bit of work, finding out the property numbers for all the fields you want included.
(If you go down this route, and it works, maybe you can post back the SPARQL query you end up with.)
I played with it for a little while and couldn't make sense of it. The best I could do is gettting an exception which at least showed to me what they were using:
