In recent years, big data and smart computing have drawn much attention and interest in many disciplines including computer science, information technology, and social sciences. The 2015 International Conference on Big Data and Smart Computing (BigComp 2015) provides an international forum for exchanging ideas and information on current issues, challenges, research results, system developments, and practical experiences in these emerging fields. BigComp 2015 invites authors to submit original research papers and new work-in-progress reports in any aspect of big data and smart computing. Accepted papers will be published in the proceedings with an assigned ISBN number and submitted to IEEE Xplore, SCOPUS, and EI Compendex.
