In order to be part of a modern society, Parliaments must open up to the public in the process of making new laws. The approach presented in this paper is conceptualized as a social system where information and communication technologies can change: (i) the way people interact with their elected representatives in Parliaments, (ii) the way people access to parliamentary proceedings and (iii) the way people subscribe to new parliamentary contents. In this paper, we explore the use of multimedia content delivery technologies, semantic technologies, personalized retrieval of multimedia contents and social feedback in order to present a smart information system for parliamentary proceedings. Currently, this approach is being developed for plenary sessions of the Parliament of the Canary Islands.
