Objective: It aims to map, analyze thematically, semantically, and discursively the articles published in the area of Knowledge Organization within the five published volumes of the events of the International Society of Knowledge Organization Brazil (ISKO-Brasil) and the eight volumes of the North American Symposium on Knowledge Organization (NASKO). Methodology: The methodology used was to survey pre-established pivot statements of the scientific production published in the annals of both events with the help of Sketch Engine software as a tool and approach 6 – Historical studies of structures and services of information in domains, 8 – Epistemological and critical studies of different paradigms, assumptions and interests in domains, 10 – Studies of structures and institutions of scientific and professional communication in a domain, from Hjørland (2017), and 13 – Discourse analysis of domain analysis as a methodological contribution, from Smiraglia (2015) and Barros (2023). Results: The survey yielded 131 articles for ISKO-Brasil and 132 documents for NASKO. It was found that, even though the two corpora analyzed are within ISKO's scope, there are divergences regarding the understanding of concepts, as well as their relationship with the epistemological discussion of the area and convergences concerning the concepts of 1) Domain Analysis; 2) Organization Systems; 3) Concept Theory; 4) Classification Systems. Conclusion: The analysis made it possible to envision Knowledge Organization as a theoretical and applied area based on Concept Theory and Domain Analysis.
