The role of Intelligent Systems in the context of the Information Technologies is clearly established. This kind of approach allows the inclusion, in computational systems, of human intelligence related concepts, like reasoning, learning capability, evolution, adaptation, autonomy, social interaction, or pro-activity. Historically, this has been the focus of Artificial Intelligence research. Meanwhile, current world dynamics made those features a real necessity in a many diversity of systems, in different application domains: from recommendation systems to robotics, to data mining, natural language processing or interactive games. Technological development made possible full-featured intelligent systems development, making many of these an integral part of everyday life for the common citizen. Additionally, potential application in many different knowledge domains and sectors of the society is turning their development more interdisciplinary, with expected contributions in engineering, and computer science, but also in human and social sciences. In the previous seven editions, this workshop has consolidated its goal of developing a forum dedicated to the reflection and discussion around intelligent systems conception and development, both from a theoretical and practical perspective. The intention is to gather people from the scientific community, industry, and society, to debate the state of art on models and architectures, as well as paradigms and frontiers that motivate intelligent systems development. Artificial Intelligence, human cognition models and computational theories, knowledge representation and engineering, information infrastructures, web distributed intelligent systems, are also themes to be explored in this workshop.
