Processamento de linguagem natural para interação entre usuários e agentes pedagógicos em ambientes virtuais de aprendizagem.

Abstract

In order to improve the process of knowledge acquisition in virtual learning environments, are sought more natural interaction methodologies between the student and the environment. As language is the main means of communication used by humans, an environment that allows the student to express themselves through their natural language can add comfort to the interaction process. In addition, it is common for these virtual environments to have pedagogical agents to assist the student in the learning process. The purpose of this work is to develop the chatterbot capacity of the pedagogic agent Dóris, to interact with the student through written natural language. Thus, through the research and development of efficient techniques and methods of natural language processing, wanted to add the chatterbot characteristic to Agent Dóris. The results obtained allowed to conclude that methods and techniques of natural written language processing can benefit the interaction process of a pedagogical agent with a user.
