With the spectacular development of new sensors technologies and the emergence of sensor networks, Big Data Systems (BDS) are becoming a very important research stream involving analysis of huge amounts of audio, spoken, text, visual and location data, modeling of user intentions and sentiments, modeling of user relations and interactions, as well as predictive analytics for recommendation engines; statistical modeling and robust inference in the area of financial engineering, biomedical informatics. Big Data hardware provides physical platforms and infrastructure for effectively gathering, processing, storing, sharing and utilizing complex large data set anytime anywhere. In short the BDS theme is more than just analytics, but a comprehensive approach involving data acquisition, high performance computing and analytics involving key applications.
