Text Readability Analysis with Natural Language Processing Tools: The Adaptation of Coh-Metrix Metrics for Portuguese

This paper presents the adaptation of Coh-Metrix metrics for the Brazilian Portuguese language (Coh-Metrix-Port). It describes the analysis of natural language processing tools for Portuguese, the decisions taken for the creation of Coh-Metrix-Port, and a case study of the application of Coh-Metrix-Port in the analysis of original and simple accounts, i.e. texts composed in a way that the writer recasts the information from a source to suit a particular kind of reader, for kids. This tool can help assessing whether text available on the Web are suitable for functional illiterates and people with other cognitive disabilities, such as, dyslexia and aphasia, and also for children and adults learning to read and thus allowing the access of Web texts for a wider range of users.
