The Big Data phenomenon evidences a context in constant cultural, social, political and economic changes and also in Information Science with a concern in the treatment of data, to guarantee the adequate and efficient recovery, in digital environments. In this way, new horizons for information professionals are opened up. The present research presents as problematic the formation and performance of the information professional for data processing in the Big Data Age, in which the SOCs have the tools to assist in the recovery of digital knowledge. Within this context, we mean the contributions of knowledge organization systems (KOS) supported by technologies and contributions from other fields, such as Computer Science and Linguistics. Therefore, studies and research are needed to better understand the dimensions of how the information professional is preparing and dealing with the systems of knowledge organization in relation to the big data era. In the present research, the training and performance of the information professionals working with knowledge organization systems together with the big data were analyzed. For this, a curricular analysis was carried out by the IC professionals who approach the proposed theme. In this way, it is a general objective to investigate the profile of the IC professional in the KOS theme along with Big Data, to contribute to the development of the area. Specific objectives are to identify: I) what are the university degrees of these professionals, II) if these professionals have a postgraduate degree and in which area, III) the area where the information professionals are performing their duties. In this way, the curricula were retrieved on the Lattes platform, which is a database of the Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq - Plataforma Lattes do Brasil, using the filter "Area of Information Science" and search terms used were "big data and knowledge organization systems" in all fields offered by the database. Once the quantitative survey was carried out, the university training of these professionals and their professional performance were analyzed, and the professional skills and competences of the information professional in the Big Data era were discussed. their contributions. We recovered 71 curricula that work with KOS and big data, in which all these professionals concluded their doctorate, 70 of these professionals act as university professor and only 1 is not professor and is inserted in the administrative branch. It was verified that Blioteconomia is the graduation that most form information professionals working in the area of knowledge organization systems and big data together. All the curricula analyzed have some type of training in higher education, the post graduate that stood out most was in the area of information technology
