The OCTA’2019 international Multi-Conference on « Organization of Knowledge and Advanced Technologies » is a large-scale scientific event to bring together researchers and R&D professionals on ideas and common actions in the organization of knowledge while defining collaborative strategies using advanced technologies in multiple fields of research and application for society and its cultural, education, economic and industrial developments. Also, to initiate future projects in innovation in order to bring public and private institutions closer to tomorrow’s technological challenges. In OCTA’2019, the scientific projects involved in this Multi-Conference event, are: 1- SIIE (https://siie2019.loria.fr/ & www.siie.fr) on « Information Systems and Economic Intelligence », 2- ISKO-Maghreb (https://isko-maghreb2019.loria.fr/ & www.isko-maghreb.org) on « Digital Sciences: impacts and challenges on Knowledge Organization », 3- CITED (https://cited2019.loria.fr/) on « Advanced Technologies, Renewable Energies and Economic Development », 4- TBMS (https://tbms2019.loria.fr/) on « Big-Data-Analytics Technologies for Strategic Management: innovation and competitiveness », with the following state of mind: - How to strengthen alliances between multi-disciplinary and trans-disciplinary? - How to multiply skills on common study objects? - How to innovate in the solutions to found and to propose in society in respect of the sustainable development? The OCTA’2019 international Multi-Conference on « Organization of Knowledge and Advanced Technologies » aims to develop subjects like: - Information Systems: architectures, models, implementations and developments, - Economic Intelligence (or Competitive Intelligence) applying methodology, context studies and implementation of systems, - Knowledge Organization applying conceptual work, process, systems (KOS) and services, - Advanced Technologies for renewable Energies, production systems, green economy, ecological engineering, etc. - Advanced Technologies for Big Data Analytics, - Strategic Management and Systems using Big Data, - Governance Organizations applying Enterprise Strategies, Strategic Management and Economic Intelligence, etc. - “Digital Sciences”, Collective Intelligence, Digital economy on Web X.0, or Web X.Y.Z.α (ie. Web’s evolution, which aims to harness the potential of the Web in a more interactive and collaborative way, with a focus on social interaction and the assistance of an artificial intelligence), - Digital and Dematerialisation effects in the Green Economy, - Data, Big Data, Knowledge Management, Decision-making and Complexity, - Data science and new trends in Economic Development: Modern finance and technological advances, Green economy and sustainable development, Green finance, Environmental Accounting, Green marketing, Green management, e-Governance, etc. and other emergent related fields.
