Résumé en anglais

The term smart city is a fuzzy concept, not well defined in theoretical researches nor in empirical projects. Several definitions, different from each other, have been proposed. However, all agree on the fact that a Smart City is an urban space that tends to improve the daily life (work, school,) of its citizens (broadly defined). This is an improvement from different points of view: social, political, economic, governmental,... This paper goes beyond this definition and proposes a knowledge-based conceptual vision of the smart city, centered on people's information and knowledge of people, in order to improve decision-making processes and enhance the value-added of business processes of the modern city.
