Big data, le cas des systèmes d'information

In this paper, we present the main challenges “big data” raises to information systems, that is to systems dedicated to the storage and processing of data for decision making purposes. After presenting in detail two major applications of big data (information retrieval and business intelligence), we investigate the role of open data and the web in big bata applications, as well as the role the web plays in science and society. We discuss the methods and computer technologies deployed to address big data challenges, focusing on how the data is stored, processed and analyzed in order to extract knowledge. Finally, we consider the challenges big data raises to companies and citizens, especially in terms of data quality and privacy preserving processes.
