City-Driven Approach to Determine Health Services Based on Current User Location and Collaborative Information

There are several applications that consider the functionality of a recommender system, which are focused on providing medical care based on the requirements submitted by the user, also there is not work that use at the same time all technologies described below. In Noguera, Barranco, Segura, and Martínez (2012), the REJA system is proposed. It is a recommendation system that consists of a web mapping for restaurants in the province of Jaén in Spain. It is also based on the use of 3D maps. The system is considered as CARS (Context-Aware Recommendation System). The main features of REJA are the follows: provide an ubiquitous architecture, context awareness in order to adapt the recommendation to the user's current location and present a 3D interface in a mobile application with geo-visualization, location, etc. In the processing, each recommendation has a label that shows the name of the restaurant and the recommendation value corresponding to a scale from 1 to 5 stars. Moreover, additional information is provided to the user such as the location of an ATM or geographical features to offer an easy orientation. This application is innovative, because the use of mobile devices and Global Positioning Systems (GPS) is increasingly common. The benefit of the user is reflected in the use of their own information. Moreover, the navigation through 3D maps increases the ability to recognize small areas and therefore, make easier the process of locating a place by the user. In Soto (2010), an application that uses the platform Health Level Seven (HL7) protocol, mobile phone technology and GPS is proposed. It allows the computation of distance and the location of medical centers based on the device geographic position. This work proposed three types of queries: general, by category and by services. For the first one, the user specified the coverage radius. In the second, the coverage radius and the type of health center must be specified. Finally for the particular service query, the user must select a medical specialty (for example, cardiology). The validation displays a list of health centers located within specified radius. The use of these applications is important, because the results cover the need of users. Furthermore, is easy to display on the map the location of medical centers. Finally, the accuracy of the information is guaranteed due to the updating of databases.
