[16:10:24] what properties indicate that this page is about mathematics? https://www.wikidata.org/wiki/Q420904
[16:12:37] or, what query could I run to get every page about mathematics? Including, e.g., singular value decomposition but excluding Gauss/Euler etc
[16:34:42] Durbley : "topic" delimitation is not an easy stuff. In your question, you affirm your own delimitation of the topic, where mathemacians (people) are not part of "mathematics".
[16:36:22] sounds like im gonna have to use dbpedia
[16:37:33] well, if we ignore that distinction I made between mathematics, how can I tell *at all* that SVD is mathematics using wikidata
[16:37:44] Under the https://en.wikipedia.org/wiki/Category:Mathematics (classified as "Main topic classifications") there are a lot of stuff (people, books)
[16:39:18] "?page dct:subject/skos:broader* dbc:Fields_of_mathematics."
[16:39:30] seems doable with dbpedia, no?
