SUMMARY:

Human communication has undergone a drastic change with the emergence of technologies that have removed a barrier for great distances between people. These days, this evolution allows them to connect in such diverse ways that many devices can combine text, image and sound into messages that redefine social relationships. Furthermore, in recent years, new technologies for storing and processing large volumes of data allow the information collected in real time to be used for the development of innovative solutions involving algorithms and methodologies that are still the focus of research in many areas . The call data records or CDRs (Call Detail Record) that arise in the context of large volumes of available data, incorporate a huge amount of information and if the amount of data searches using complex networking tools. Information on how, when, and with whom customers communicated at any given time, plus the approximate location of the same valuable data that can be picked from CDRs. Based on data, studies have emerged proposing models of social networks and mobility analysis in recent years, offering new possibilities and a search for innovations. This work uses telephone records from two immediate regions in the state of Minas Gerais, Brazil: the immediate region of São João del-Rei (small size) and the immediate region of Juiz de Fora (medium size). Thus, this work has as main objectives the characterization of social interactions from phone calls records and an investigation of the relationship between social interactions and mobility patterns by reference in urban centers. Urban complexity analyzed in this work from two perspectives: social and mobility. A social perspective allows us to understand how an interaction between pairs of products takes place, revealing specific aspects about human relationships in urban contexts. From the perspective of mobility, it is possible to understand how owners interact with the urban space and what can help to characterize the organization of cities and individuals. With the investigation of a relationship between social relationships and mobility patterns, the experiments carried out aimed to explore the impact of disabling those who have a relevant social relationship on the mobility patterns of other guests. Thus, analyzes regarding mobility patterns were evaluated in order to measure a pattern similarity between patterns. The characterization of each network was also carried out to allow an understanding of the basic norms, in addition to studies of more complex characteristics such as reciprocity and detection of network communities, which are currently metrics of high interest in the field of study of social networks. In this way, this work integrated a rich set of information in the context of social networks for regions in an unprecedented way.
