Uma arquitetura para gerenciamento e recomendação de ações baseadas em contexto lógico mediante dispositivos móveis

Abstract

This paper elaborates a software architecture that addresses within mobile devices on the Android platform, collecting information from the physical context of location (only information that is collected outdoors) and generation of logical context of location (information they need processing of the data to be found indoors) and stores this information in a Semantic Web structure which suffer inferences to generate a context logical of recommendation to use resources available on the mobile device and used previously by the user at a given time and local. The functionality of this architecture will be test by construction a prototype on the Android platform. One of the challenges of this work will be to collect the context of logical device location in indoor locations such as buildings and houses where the signal strength of the Global Positioning System (GPS) is insufficient to be identified, so this work will be used and accelerometer sensors gyroscope present in mobile devices to calculate your speed and direction. The location will be integrated inside the external location, forming a continuous path. The information collected in the physical context is stored in the ontology within the mobile device and synchronized with a remote server. Another challenge of this work is the development of a software agent that through data stored in the ontology on device, makes inferences on the data stored in the form of Web Semantic and provides recommendations for use of a given resource, based only on historical data of these resources by relating the approach in a certain place with the frequency in time over the same time of day or the same day of the week and the same day of the month. The architecture of this work is being called and Context Manager is integrated with the other two studies did not present this work: a Semantic Desktop with the task of identifying a resource that is being used to send and manager context; and Context's Federation, serving as a remote server, with the task of receiving context data collected by the context manager. The storage of context collected in a Web Semantic structure enables the union of this information with other context information that characterize a device, an individual or a society. The expected outcome of the architecture presented here will be the greatest possible degree of accuracy in the identified geographical position and consistency of recommendations for the use of resources available on the mobile device at a given time and place.
