Viewing by parliamentary affinities between data votes in Brazilian senate

The expansion of citizen participation in the public sphere depends directly on access information on the performance of elected representatives, especially with regard to their voting decisions during their terms. The Information Science can assist in this process, proposing and evaluating models of access to such information that may be obtained from data to be provided by the official websites from legislative, in levels federal, state and municipal.

We proposed in this paper to analyze the process of collecting and using data about votes of senators in order to promote the use of this model in other spheres.
