Innovation and Digital Business Innovation are key pillars in sustainable growth. DoCEIS 2014 focuses on socio-technical systems capable of harnessing collective intelligence for promoting innovation and taking better, informed and sustainability-aware decisions: Collective Awareness Systems. These systems leverage the emerging "network effect" by combining open social media, distributed knowledge creation and data from real environments ("Internet of Things"), thus linking objects, people and knowledge in order to foster new forms of social and business innovation. DoCEIS 2014 is aimed as an international forum for presentation of research results coming out of PhD works, and a space for discussion of post-graduation studies, PhD thesis plans, and practical aspects of a PhD work. Among other activities, it includes: Presentation of research results by PhD students (co-authored by their supervisors) Tutorials by invited experts on scientific, methodological, or soft skills topics. Presentation and discussion of the base ideas of the thesis plans. Discussion of the scientific and technical challenges in the several Electrical and Computer Engineering specialization areas. Sharing of experiences among PhD students from different geographical regions. Forum on practical aspects (e.g. Publications, job market, careers, etc.). Creation of collaborative (social) networks. Prospective authors of research papers are invited to submit their manuscripts reporting original work, in any of the scientific areas of the conference. Papers describing advanced prototypes, systems, tools and techniques and general survey papers indicating future directions are also encouraged. Following the successful previous editions, proceedings are expected to be published by Springer, IFIP AICT series (and submitted for indexation in Web of Science). Best papers will be considered for possible inclusion in a special journal issue. There will be also poster discussion sessions regarding theses’ plans. These sessions are designed in order to provide early feedback to PhD candidates in the initial phase of their studies.
