Abstract

EvaTalk is a complete chatbot system developed to attend users from Escola Virtual de Governo (EV.G), which is a Brazilian virtual school maintained by the federal government. The proposed architecture was based on a framework to build chatbots, but it was necessary to replace and adapt services to attend EV.G needs. The architecture is composed of the following modules: Interface for direct interaction; Artificial Intelligence to comprehend and process messages; Development to deal with the knowledge base; and Business Intelligence to analyze messages. The first version responded to questions related to Institutional Membership and chitchat. Still, it was noted that Eva needed more training data considering that the developers could not predict well user behavior. Therefore, it was necessary to change the conversational data examples and flows to match user behavior observed after release, which showed an increase in the chatbot’s response confidence. The system relies mostly on the data collected through the data analysis tools to evolve.
