In pyblimoetric's AuthorRetrieval there is an object called classificationgroup.
In the documentation describes it as:
List with (subject group ID, number of documents)-tuples.
But what is a "subject group ID"?
Where do I find a list of all possible "subject group ID"s and their definitions?
These are Elsevier's All Science Journal Classification (ASJC) codes.
More on that https://service.elsevier.com/app/answers/detail/a_id/12007/supporthub/scopus/~/what-are-scopus-subject-area-categories-and-asjc-codes%3F/
Scopus assigns 4-digit ASJC codes to all sources (journals, conference proceedings, books, trade journals). A source has between 1 and 7 ASJC codes. All publications in a source are assigned all the ASJC codes of the source. This implies the same publication can be counted multiple times in
.classificationgroup.
