Syntactic parser for Brazilian Portuguese: challenges and solutions

This article aims to present the Syntactic Parser for Brazilian Portuguese - Parsero, developed from the Generative Grammar (CHOMSKY, 2015) (Original published in 1957) improved by the X-Barra Theory (CHOMSKY, 2014) (Original published in 2012). Therefore, were used the rules developed by Othero (2009) especially for Brazilian Portuguese and adapted by to meet the needs of our Parser. The research used as lexical collection, to populate a Structured Query Language (SQL) Database, the resource Dictionary of Simple Inflected Words for Brazilian Portuguese (DELAF_PB) that was made available by the Unitex-PB Project, developed by NUcleo Interinstitucional de Linguistica Computacional (NILC) and by Instituto de Ciencias Matematicas e de Computacao (ICMC). This resource, in turn, was built based on the French formalism - Dictionnarie Electronique du LADL (DELA) (MUNIZ, 2004). As a result of our project, we have made available to researchers interested in the topic the SQL Database with 1,193,295 classified lexical units, the address with the open source of Parsero and a link to run the application. Throughout the development of the Natural Language Processor (NLP), we had to put into practice interdisciplinary studies from the language sciences and computer sciences, a necessary practice for the development of intelligent programs that can interact with writers or Brazilian Portuguese speakers.
