Dr. Vangelis Karkaletsis, Research Director, NCSR "Demokritos"

Vangelis KarkaletsisIn this talk we will present our activities, addressing challenges that arise when applying data analytics to heterogeneous and large-scale data. Heterogeneity and transparent distribution are the focus of the SemaGrow project (, approached as federated querying that is transparently optimized and where semantic transformations are dynamically applied. The outcome is a stack of technologies that simplify both the inclusion of heterogeneous data sources to a federated end-point and the development of client applications for this end-point. The SemaGrow Stack will be integrated in the Big Data Aggregator that is developed in the recently started Big Data Europe project ( The Big Data Aggregator will be piloted on diverse and challenging use cases defined by domain experts across the board of data-intensive science and technology.
