Summary

This book constitutes the thoroughly refereed proceedings of the 7th International Workshop on Computational Processing of the Portuguese Language, PROPOR 2006, held in Itatiaia, Brazil, in May 2006.The 20 revised full papers and 17 revised short papers presented were carefully reviewed and selected from 56 submissions. The papers are organized in topical sections on automatic summarization, resources, translation, named entity recognition, tools and frameworks, systems and models, information extraction, speech processing, lexicon, morpho-syntactic studies, and Web, corpus and evaluation.
