It is our great pleasure to welcome you to the 2015 International Workshop on Human-centric Independent Computing -- HIC'15. This workshop aims at providing an open forum to reach a comprehensive understanding to the recent advances and challenges in an emerging research field -- human-centric independent computing -- that studies means, ways, mechanisms that prompts human beings to be relatively independent of the present computing paradigms (or connected world). The first event was held in conjunction with IEEE SSCI 2014 (http://www.ieeessci.org/ISIC.html) in Orlando, U.S. The core challenge, which discusses the over-connected phenomenon of Internet users, is similar but the connection among users and social media (or its derives such as experience, trust, semantic correlation, etc.) is especially concentrated. As the second event, we still have many submissions coming in discussing the similar challenges from last year. The call for papers attracted submissions from Japan, Taiwan, India, Portugal, France, and United States.

The papers accepted for inclusion in the conference proceeding primarily cover the topics: database and data mining, networking and communications, web and internet computing, embedded system, soft computing, social network analysis, security and privacy, and ubiquitous/pervasive computing. Many papers have shown their great academic potential and value, and in addition, indicate promising directions of research in the focused realm of this workshop series. We believe that the presentations of these accepted papers will be more exciting than the papers themselves, and lead to creative and innovative applications. We hope that the attendees (and readers as well) will find these results useful and inspiring to your field of specialization and future research.
