Análises de Palavras-chave como Fonte de Dados para Obtenção de Conhecimento Sobre a Evolução da Ciência

Services such as digital libraries and sites for individual registration of scientific output are examples of how the internet has contributed to the amount of published work, allowing users not only to access available content, but also to record their scientific output. In this context, researchers from all domains have dedicated efforts to analyze scientific production from different perspectives, such as: citation analyzes, productivity indicators, scientific collaboration and analysis of topics based on terms abstracted from titles, titles and keywords of scientific articles. Among the works found in the literature, the analyzes generally use international repositories, which are specific to a particular area or periodical. However, because they deal with specific analyzes and use of international repositories, they can not comprehensively represent what is produced in Brazil. Thus, analyzing a data source that encompasses several types of publications, especially in national vehicles of different areas, becomes a relevant task for the understanding of Brazilian science. Therefore, a temporal analysis of the main keywords in the scientific articles of all the individuals with a doctorate completed that have the curricula registered in the Lattes Platform is proposed in this work. In order to do so, the keywords of the articles published in annals of congresses and periodicals are extracted and processed, to be later analyzed through bibliometric analyzes and social network analysis techniques, to highlight the main topics of Brazilian researchers' interests. all the major areas of knowledge over 55 years of research registered in the Lattes Platform curriculum
