MediaWiki search + WhatLinksHere[edit]

Is there a way to combine these functions?

Like for example Wikipedia:Category_intersection#Using_MediaWiki_search_to_find_category_intersections shows how to find articles which are included in a certain category. So say I linked to Category:Time_travel_television_series

But then what if I wanted to intersect that with all articles linked from List of animated television series of 2012 ?

There is not a corresponding category for this list. The closest is Category:2012 in animation which isn't populated.

I hope it will be able to do subcategories since then something like Category:2012_television_series_debuts could be used more freely. Ranze (talk) 17:17, 8 January 2017 (UTC)

If you use WP:AWB, the "list comparer" function in that app could generate exactly that list (it includes both "articles in category X" and "links on page" as set options) — and you could then use the resulting list as either the batch-set for a processing job, or save it as a text file on your hard drive if you needed to do that for some reason. But there isn't anything at the server level that could generate that list for you as a Wikipedia page. Bearcat (talk) 21:40, 8 January 2017 (UTC)

Integration with Wikidata[edit]

Could I use a category intersection to create a list of topics, then feed that list into a wikidata search and retrieve additional data? Could I then create a (external) Web page that displays this info in the form of a table? Could this be done automatically? Thanks. SharkD  Talk  13:30, 12 March 2017 (UTC)
