Desarrollo de un chatbot genérico para un sistema domótico residencial aplicando procesamiento de lenguaje natural

Abstract

Today technological advances have become part of our lives, so that the use of smart devices is essential to stay connected with our loved ones and friends. One of the most important advances is the so-called internet of things; It is about having several devices connected and communicating with each other, from household appliances to smart devices that allow us to control our health status. From this concept the term home automation is born, where the main idea is to be able to control and obtain data from a home, such as the people who live in it or the status of our devices such as lights or televisions. Currently many technology brands have made many advances in the development of their own devices and applications to control them; From this point, a conflict arises that platforms such as OpenHab resolve and that is the fact of grouping devices of different brands and having a central application that allows their use from a single application. Although aspects such as security are somewhat marginalized, since it depends a lot on the platform to be able to obtain data from a camera system and in some cases it is not possible. When talking about controlling or managing a home, a scenario is proposed where the user is close to the system, that is, they feel that the system can be a fundamental part of their routine life; Although many applications are currently only worked on a routine basis, there are technologies that have been worked on so that the user has a closer feeling with a system; this is the so-called virtual agents or chatbot. Which work based on artificial intelligence algorithms which allow a system to be trained with the phrases that a user can provide naturally. In order to generate orders based on natural language processing, the system must be able to understand a phrase based on keywords that are related to previously configured entities, in this way the intention of the phrase is understood and a response can be generated. programmed in a more natural way. With all this it is achieved that a user is more familiar with a system. This technology has been used in this project to develop a more friendly system capable of understanding commands from any phrase entered by the user and whose intention can be understood. Based on all of the above, the purpose is to develop a prototype for a home automation system that allows aspects such as security and entertainment to be brought together in a single, friendlier system, in such a way that natural language processing technology is incorporated into a chatbot; This will allow obtaining data from the residents of the house and in turn control an intelligent device such as a Smart TV. The tools used for the development of the project have been OpenHab, Raspberry Pi, Node.js language and the wit.ai natural language processing tool. In turn, a database was also used where it is used to obtain records of residents and send orders that allow access to housing
