It is a pleasure to invite you to the 8th Edition of international conference INTIS. The success of the previous seven editions encourages us to continue with the same ambitions and enthusiasm by launching this call for this eight (8) edition. INTIS 2019 will be held in the city of Tangier (Morocco) during 20-21 December 2019. The National School of Applied Sciences of Tangier, Abdelmalek Essaadi University, the Moroccan School of Engineering Sciences and Data Engineering & Systems Team will jointly organize this INTIS 2019 edition. This eight edition, with a strong connotation in Artificial Intelligence, Big Data and IoT, Healthcare 4.0, will allow researchers who have already participated in previous editions to find themselves in the same context for presenting their latest scientific works. The INTIS conference addresses also professionals who are involved or interested in the decision- making domain, who, through their pragmatic vision, will contribute by expressing new requirements or by valuing existing solutions. INTIS is also an opportunity for Ph.D. students to expose and reveal their work and to make themselves part of this community. This event in Big Data and IoT sectors will allow discovering specialized works in these fields, as well as receiving many feedbacks.
