Um método para desambiguação em língua portuguesa, integrado ao processo de tradução do Sistema Falibras

Abstract

There are more than 1 billion people in the world with some type of disability. In Brazil, this reality corresponds to about 23.9 % of the 190 million Brazilians; among these 9.8 million have some hearing impairment. Deafness makes social interaction considerably more difficult, since it inhibits the individual from communicating through the oral-auditory pathway. These communication problems usually impair considerably the interaction of deaf students with fellow listeners, impairing the process of social integration. To facilitate communication between deaf people and listeners, Portuguese-Libras machine translation tools can be used. However, according to reports in the literature, about 75 % of the deaf community feels dissatisfied with the translation of the existing tools and among the main causes of this dissatisfaction are the use of inappropriate signs for words with semantic ambiguity (eg, direito, público ). In this work, the improvement of the Falibras System translation module is proposed, with the objective of improving the quality of the translation with respect to the criticisms observed in the literature. The main objectives of the proposed project are: (1) to know the state of the art regarding the resolution of ambiguities in Portuguese; and (2) combining existing techniques to develop an ambiguity resolution module for Falibras. The evaluation of the results have considered the accuracy metric, in a comparative way with existing works in the literature. The evaluation was conducted based on the Goal-Question-Metric method and presented promising results.
