Proceedings of the 2017 ACM Workshop on Multimedia-based Educational and Knowledge Technologies for Personalized and Social Online Training. Abstract: It is our great pleasure to welcome you to the 1st International Workshop on Multimedia-based Educational and Knowledge Technologies for Personalized and Social Online Training -- MultiEdTech 2017. Educational and Knowledge Technologies (EdTech), especially in connection to multimedia content and the vision of mobile and personalized learning, is a hot topic in both academia and the business start-ups ecosystem. The driver and enabler of this is on the one side the development and widespread availability of multimedia materials and MOOCs, which represent multimedia content produced specifically for supporting e-learning; and, on the other side, the ever increasing availability of all sorts on information on the Internet and in social media channels (e. g., lectures, research papers, user-generated videos, news items), which, despite not directly targeting e-learning, can prove to be valuable complements to the more targeted learning materials. Although the availability of such content is not a problem these days, finding the right content and associating different relevant pieces of multimedia so as to enable a comprehensive learning experience on a chosen subject is by no means a trivial task.
