Desarrollo e implementación de un chatbot con bot framework. Caso de estudio: servicio a estudiantes de la Carrera de Software.

Abstract

The objective of this curriculum integration work was the development and implementation of a chatbot which will be used by the students of the Software Career to obtain information on frequently asked questions that arise from the development process of the work and community practices of the career. Talking about the development of the chatbot, we utilized the Bot Framework with the C# programming language. We utilized the natural language processor, Language Understanding Intelligent Service (LUIS) to provide the chatbot with artificial intelligence, and the Qna Maker web service. The implementation of the chatbot was carried out through two communication channels (Facebook and Telegram). We utilized the agile SCRUM methodology for the planning and development of the chatbot, and we stablished methods and techniques for each of the objectives that were set. In the planning phase, we identified 10 user stories, 3 enablers and 4 sprints, for the development phase, we developed the process diagram and dialogues and moreover, we adapted the workflow by creating flowcharts. Finally, in the closing phase, we utilized a burndown chart to demonstrate the fulfillment of the sprints and we utilized the Chatbot Usability Questionnaire (CUQ) to evaluate the chatbot, which measures the usability of the conversational agent. The results obtained demonstrate that the chatbot obtained an average score of 84.7, concluding that the chatbot is highly usable and at the same time is able to satisfy all the defined requirements. It is recommended to expand the knowledge base of the chatbot in order to improve the responses when interacting with users.
