Entendendo a Evolução Temporal em Redes Complexas

Fernando MourãoWagner Meira Jr.

Several practical problems are described by a set of objects and the relationship between them. Understanding the relationship between these objects and selecting which data will be used in the analysis of relations is essencial to a proper characterization of the defined model. Most of the applications considers all available information for analysis, aggregating it over time. In this work, we studied the impact of information aggregation over time for the characterization in complex networks. We work with a generic model of network, applicable to a large and diverse range of areas. We propose and apply in a real database, a verification methodology of this impact over time. The results enabled us to conclude that analyzing the aggregate information degenerates the characterization of the network studied.
