ATAS - Academic Text Analysis System

The ATAS -Academic Text Analysis System (Brazilian Portuguese SATA -Sistema de Análise de Textos Acadêmicos) is open-source software to support textual content analysis.Inspired by Bardin's method (Bardin, 2020), ATAS streamlines extraction, filtering, and statistical analysis of academic texts to surface semantic and linguistic patterns.It is particularly useful to Humanities and Social Sciences (Geography) researchers, offering tools for keywords, bigrams, lexical categories, and other quantitative text measures.ATAS integrates NLP workflows and exports data to tools such as Gephi for semantic network analysis (Bastian et al., 2009).The toolset is localized for Brazilian Portuguese and is actively used by the GETE -Grupo de Estudos Territoriais (Territorial Studies Group) at UEPG and the GEPES -Grupo de Pesquisa Redes de Poder, Migrações e Dinâmicas Territoriais (Research Group on Power Networks, Migrations, and Territorial Dynamics) at UNICENTRO (Brazil), both operating in Master's and PhD programs.
