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. This 3.0 version of Coh-Metrix-Port features 46 metrics, detailed here (in Portuguese).
