The selection presented here does not intend to represent the single best solution. It is a good solution considering the target natural language. 1 Natural Language Processing The natural language processing component, as in many systems and as described in Chap. 2, is organized in four sequential steps: sentence boundary detection, POS tagging, NER, and syntactic parsing. Before getting into details about the processing pipeline, it will be described the corpus used to prepare most of the tools for Portuguese.
