El metodo elaborado cuenta de tres fases: marco semantico y de datos, otra que implementa el sistema de recomendaciones y una encargada de la visualizacion de las recomendaciones. La fase de sistema de recomendaciones implementa un filtro espacial, un filtro semantico y otro colaborativo. Las recomendaciones generadas muestran los elementos de posible interes, estas pueden ser visualizadas en forma tabular o combinadas con informacion espacial. Se comprobo por medio de un experimento y diferentes metricas aplicadas, el incremento en la efectividad del mismo para usuarios moviles segun sus preferencias en cuanto a las recomendaciones dadas en un ento...

The large volume of information, its variety and the speed with which the analyzes are required have been a constant in this work. Until recently the solutions to these problems were always related to changes in architecture, index optimization, increased computing resources, etc. Although technologies related to BigData were already used in the global context, it is not until recently that, thanks to the benefits of Docker, they were enabled for wider use. Within the framework of this investigation, it allowed us to test and evaluate a variety of tools of this type and consider them as components of our architectures. During this period, three BigData Geospatial technologies that are Geomesa, Geogrellis and MrGeo have been evaluated in an experiment whose objective is to complete a management flow that includes fro...

This research provides spatial and semantic components to build Collaborative Recommender Systems. The use of web services derived from the Spatial Data Infrastructure of the Republic of Cuba, which constitutes the main spatial data source accessible via Web in the country, is particularly relevant. The inclusion of concepts from Semantic Web, as ontologies and semantic query services, allow information retrieving used by Recommender Systems engines more effectively. A methodology based on two stages of filters (spatio-semantic and collaborative filters) is described. In the first stage, considered the pre-filtering, spatial and semantic filters are explained. Once the information necessary for the Collaborative Recommender System is obtained, the resulting points of interest and user preferences are processed by the Collaborative Filter. Finally, some elements of a Recommender System implementat...

One of them is an application to locate vehicles based on Web to follow mobiles on vectorial cartography and raster, designed for controling fleets. This application allows the mobiles ’ monitoring of a remote form on a network of communications, making possible to rebuild the behavior of the vehicle in a certain period of time, re-preparing his trajectory and analyzing his speed, detentions in authorized destinations or not, etc. by means of information stored in a historical database, it also provides to the user a group of tools for the handling of maps, similar to the tools of professional softwares for handling the Geographical Information System. Its architecture is focused to services, there is produced the integration and linking of several proces...
