Scope
Intelligent Systems are those that incorporate aspects usually associated with intelligent human behaviour, such as perception, reasoning, learning, evolution, adaptation, autonomy, social interaction and pro-activity. Historically speaking, this is one of the main focuses of interest in Artificial Intelligence. However, the dynamic contemporary world has turned such characteristics a requirement in virtually every information system. As time evolves and given the fast technological development, intelligent systems are becoming even more feasible as they take part in our daily lives. Additionally, their great potential of application in different knowledge areas and sectors of the society turns its development even more interdisciplinary, with contributions from many different areas, not only engineering, computer science and informatics, but also from human and social sciences.
This workshop is aimed at building an adequate forum for the discussion of the many aspects related to the creation and development of intelligent systems, both from a theoretical perspective and from the practical exemplification of their potential applications. We intend to gather the scientific community, industry and society to discuss on the state-of-the-art models and architectures, as well as on paradigms and frontiers that motivate much of the advance of intelligent systems. Areas such as Artificial Intelligence, computing theories and models of the human cognition, knowledge representation and engineering, information infrastructure and distributed intelligent systems on the Web are some of the areas to be explored and deepen in this workshop.

Topics of Interest
The topics of interest for the workshop include, but are not limited to the following areas:
• Artificial Intelligence
• Agent technology and multi-agent systems
• Cognitive and adaptive robotics
• Knowledge-based systems
• Machine learning
• Electronic Commerce
• Adaptive business intelligence
• Semantic Web and Ontologies
• Information retrieval
• Data and knowledge engineering
• Knowledge discovery from databases
• Data mining and OLAP
• Human-Computer Interaction
• Ubiquitous computing and mobile systems
• Service oriented architectures
• Expert and decision support systems
• Intelligent entertainment systems
• Evolutionary computing and other bio-inspired models

Paper Submission and Formatting Guidelines
We invite prospective authors to submit their contributions, not yet published, reporting on either work under development or concluded projects about theoretical aspects or practical applications related to the topics of the workshop. Contributions can be submitted in one of the three formats of the Conference, namely as full paper (6 pages), as short paper (4 pages), or as poster (2 pages).
The paper preparation must follow the formatting guidelines of the Conference (DOT, PDF), and should be written either in Portuguese, in Spanish, or in English. All contributions must be submitted in PDF format, through the EasyChair platform (https://www.easychair.org/conferences/?conf=wisa20110). At least three members from the workshop’s Programme Committee will assess and comment on each submission, following a “blind-review” process. Therefore, authors should take special care to delete their names and affiliation from the paper during the reviewing phase, as well as obfuscate any other references in the text that can possibly identify them.

Publication
Regardless of the type of submission, the Workshop’s Programme Committee may suggest papers to be accepted as full-paper (6 pages), short-paper (4 pages) or poster (2 pages). Full papers will be included in the Conference’s main Proceedings, both on paper and on CD support, whereas short papers will be included only in the proceedings on CD support. The papers selected for presentation during the Workshop, to be include in the Proceedings, are subject to the condition that at least one of the co-authors performs a full-registration at the conference and ensures its oral presentation.
Historically, all editions of the CISTI Conference have been indexed by Thomson’s ISI. This 6th edition is additionally a Conference with the formal support of IEEE. Therefore, the published papers will be made available on the Xplore digital library and will also be indexed by Inspec and Scopus. They will also be made available and indexed by EBSCO.
