Knowledge organization systems (KOSs), such as term lists, thesauri, taxonomies, andontologies, play a fundamental role in categorizing, managing, and retrieving information. Inthe academic domain, KOSs are often adopted for representing research areas and theirrelationships, primarily aiming to classify research articles, academic courses, patents, books,scientific venues, domain experts, grants, software, experiment materials, and several otherrelevant products and agents. These structured representations of research areas, widelyembraced by many academic fields, have proven effective in empowering AI-based systems toenhance the retrievability of relevant documents, enable advanced analytic solutions toquantify the impact of academic research, and analyze and forecast research dynamics.We aim to present a comprehensive survey of the current KOS for academic disciplines.We analyzed and compared 45 KOSs according to five main dimensions: scope, structure,curation, usage, and links to other KOSs. Our results reveal a very heterogeneous scenario interms of scope, scale, quality, and usage, highlighting the need for more integrated solutionsfor representing research knowledge across academic fields. We conclude by discussing themain challenges and the most promising future directions.
