### Space Management through Voice Assistants  
Usually, the management of spaces in a university is carried out by an interested party who can be a teacher or an administrator. In the case of a teacher, they usually request a specific laboratory or classroom to carry out activities such as classes, seminars, workshops, etc. Using their profiles, administrators can reserve a space such as a meeting room, office, etc. Due to the large number of events and activities in a university setting, all these spaces generally present problems of availability. The model used to execute a request is a computerized reservation system. This system registers a request, but this is susceptible to changes by an administrator, who verifies the suitability and importance of the event before executing it [47]. This model works, and the user adapts to it. However, the process can be improved to make it more efficient. One aspect that needs to be improved is the availability of the service because the process can only be accessed locally through the intranet of the university participating in the study. Another area that needs to be improved is the interaction with the user. Technological advances force the system to make use of personal assistants whose use transforms the user experience into a positive one. Finally, what is expected of the model is that it takes care of the whole process, from the making of the request to facilitating the notification of the event to those interested. In Figure 5, it is possible to see how the model works and the devices it uses. The model uses voice assistants that use Amazon Echo (Alexa) technology. These devices are currently used in homes or offices in order to perform a range of tasks such as managing several devices that use the Amazon protocol to performing a specific action [48]. The capacity of these devices and the facilities which they present for the generation of skills mean that these devices can carry out several complicated tasks at once and provide access to different sectors of society. For this work, an application has been generated that connects to the database that is responsible for registering space reservations. In addition, the system also uses the results of a BI. This platform is responsible for verifying the availability of each of the spaces that the university has available and gives weight to the importance of each event. Weights are assigned based on the number of attendees, the number of people outside the university attending the events, the number of exhibitors, and whether these are external or internal. These are some of the parameters that the BI uses to define the importance of an event in order to allow it to allocate the appropriate space efficiently [49]. The interaction with the applicant takes place in natural language and uses voice recognition to determine who the applicant is and his/her profile. Once the system has all the data it requires, Alexa Echo takes control and makes available to the applicant all the options for the proposed reservation, such as day, time, available rooms, etc. The user interacts with the device according to their needs and the options presented by the model, as would traditionally be done by a human assistant. Once the space has been reserved, the device asks the user if it should send a notification to the interested parties and to make the agenda for the event. If the response is positive, the system immediately sends a notification via email using Office 365 and adds the event data to the calendar of each interested party. The use of this technology improves the user experience while at the same time reducing the personnel needed to perform this process. Figure 5 aligns each of the components of the model with the components of the university campus architecture. The model even allows the university to make reservations or launch a videoconference immediately. This is part of the reservation process with regard to available spaces, and it also presents an option for certain events.
