Title: Special issue on contributions of computational intelligence in designing complex information systems
Abstract: During the last decades Computational Intelligence (CI) has emerged and showed its contributions in various broad research communities (computer science, engineering, finance, economic, decision making, etc.).This was done by proposing approaches and algorithms based either on turnkey techniques belonging to the large panoply of solutions offered by CI such as data mining, genetic algorithms, bio-inspired methods, Bayesian networks, machine learning, fuzzy logic, artificial neural networks, etc. or inspired by CI techniques to develop new ad-hoc algorithms for the problem under consideration.The main objective of our special issue is not to cover the contributions of the CI in all domains, but in the particular field of computer science, which is Information Systems (IS).ISs are repositories where sensitive and crucial data are recorded to support day-to-day company applications and decision-making processes.Building such systems usually passes through several complex steps: (a) requirement analysis, (b) design, (c) implementation, (d) testing, (e) evolution and (f) tuning.Moreover, two other crucial aspects should be taken into account when building IS: (1) the big data dimension and (2) the advanced deployment platforms such as cloud that comes with B Ladjel Bellatreche
