Aspects

Egon Willighagen edited this page Jan 3, 2026 · 14 revisions

Scholia displays content using various aspects, like author, work, venue, and multiple specific topic pages like chemical. The views.py script has a classes_to_aspect() method that will suggest the default aspect to use for that item.

The below lists can be extended by limiting them to a minimal number of wiki sitelinks by adding ?item wikibase:sitelinks ?sitelinks ..

Content on this page is available under the terms of the CC0 1.0 Universal Public Domain Dedication (CC0 1.0).

Random elements for aspects

The next section has SPARQL queries to list items that can be expected to be opened in Scholia by the respective aspects. To get N random items instead, add ORDER BY RAND() LIMIT N.

Default aspects for items

The following SPARQL queries can be used to get a list of Wikidata items where we have a fair chance that that aspect will be suggested. Because the Python code does not use a SPARQL query but a decision tree, it is not a 1-to-1 match.
