Title: Big Data, Spatial Data and Social Networks over the Web

Abstract: Nowadays the Web and other information resources and exchange mediums such as Twitter, Snapchat and many others provide many novel opportunities for the analysis of human interactions and behaviors. This talk will introduce several examples of recent work that consider these information means as big data systems that offer several avenues for social and economic studies. I will first introduce a graph-based and computational modelling approach that derives the main structural, temporal and spatial properties that emerge from the study of an implicit research community exhibited by a series of conferences over the Web. Next I will present a study that explores large crowd behavior at the regional scale using a large geo-tagged Twitter dataset. The main idea behind this computational study is to explore human spatio-temporal patterns and moods at the regional scale in Japan. Patterns are analyzed in space and time, emotions are categorized using a sentiment-based dictionary approach. Finally I will discuss some of the many opportunities left for further research.

Title: Practical Artificial Intelligence with Big Data

Abstract: Big data are important for delivering practical artificial intelligence, but they are not the complete picture. A wide range of techniques has emerged from the field of artificial intelligence including rules, frames, model-based reasoning, case-based reasoning, Bayesian updating, fuzzy logic, multiagent systems, swarm intelligence, genetic algorithms, deep learning, and neural networks. They are all ingenious and useful in narrow contexts. It will be argued in this presentation that a truly intelligent system needs to draw on a variety of these approaches within a hybrid system. Five distinct ways to enhance or complement one technique with another will be identified. Several practical examples will be presented, ranging from medical diagnosis to the control of specialised manufacturing processes.

Title: Efficient Big Data Streaming on Modern Scale-Up Servers

Abstract: An ever-growing number of devices are capable of sensing the world by producing huge flows (data streams) of information regarding the users and the environment. A large set of applications need efficient processing techniques to extract insights and complex knowledge from such a massive and transient data deluge. Furthermore, to keep the processing in real-time, existing systems must expose parallel features to adapt the algorithms and the way the processing is performed to unpredictable and time-varying input rates and workloads.

This talk will provide a critical review of traditional Stream Processing Systems targeting large-scale distributed platforms (e.g., Apache Flink, Storm and Spark Streaming). Most of them are still inadequate to exploit the computational power provided by modern scale-up servers equipped with several multi-core CPUs and co-processors like GPUs and FPGAs. This talk will clarify the reasons for such inefficiencies, which pave the way to the design of the WindFlow library, a new C++ framework for stream processing on scale-up servers built on top of the RISC-like parallel building blocks provided by the FastFlow parallel programming environment. The talk will show experimental results on some real-world applications and will conclude with a discussion on future research problems and open directions in this research field.
