This book constitutes the thoroughly refereed post-conference proceedings of the Third
International Workshop on New Frontiers in Mining Complex Patterns NFMCP 2014 held in
conjunction with ECML-PKDD 2014 in Nancy France in September 2014. The 13 revised full papers
presented were carefully reviewed and selected from numerous submissions. They illustrate
advanced data mining techniques which preserve the informative richness of complex data and
allow for efficient and effective identification of complex information units present in such
data. The papers are organized in the following sections: classification and regression
clustering data streams and sequences applications.
