Aprendizagem de Língua Assistida por Computador: Uma Abordagem Baseada em HPSG
Resumo
Resumo: Este trabalho analisa fundamentos e métodos pertinentes para o pla- nejamento e desenvolvimento de sistemas de Processamento de Linguagem Na- tural (PLN) com o objetivo de auxiliar a aprendizagem de línguas. O foco prin- cipal é a correção sintática baseada no formalismo HPSG conforme implemen- tado no sistema LKB (Linguistic Knowledge Building). Foi implementado um analisador em linguagem Java que, juntamente com uma gramática da língua espanhola de médio porte, permite experimentar a técnica de correção através de regras de malformação. A partir dos resultados obtidos discute-se alguns aspectos práticos e a viabilidade do PLN aplicado à educação.
Abstract: This work analyses principles and methods relevant to the planning and development of Natural Language Processing (NLP) systems, whose goal is to assist in language learning. Syntax checking based on the HPSG formalism as implemented in the LKB (Linguistic Knowledge Building) system is the main focus. Java language was used to implement a parser that, together with a Spanish grammar of moderate coverage, allows us to experiment with mal-rule based checking. From the results obtained practical issues and the viability of NLP applied to education are discussed.
