Coh-Metrix-Port is an adaptation of the Coh-Metrix tool into Brazilian Portuguese. The Coh-Metrix tool calculates indexes to evaluate cohesion, coherence and difficulty of comprehension of a text, using several levels of linguistic analysis: lexical, syntactic, discursive and conceptual.
To implement all these metrics, several natural language processing resources and tools are used. Version 2.0 of Coh-Metrix-Port features 48 metrics. The system requests registration because it creates an area for each new user.
