Current focus on Big Data

− Emphasis on power of data and data mining solutions

− Technology solutions to handle large volumes of data; e.g. Hadoop, NoSQL, Graph Databases, …

− Trying to find patterns, co-occurrences and trends from large volumes of data…

− The IoT is a dynamic environment and involves lots of heterogeneous data and (often resource constraints) devices; so the data analytics for the IoT have different requirements.

Big Data for Smart Cities

−Big data should help:−empower citizens−provide more business opportunities for companies

(and SMEs) and private sector services−create better governance of our cities and better

public services −provide smarter monitoring and control− improve energy efficiency, create greener

environments… −create better healthcare, elderly-care…

Looking back, looking forward

− Combining data from Physical, Cyber and Social sources can give more complete, complementary data and contributes to better analysis and insights.

− Intelligent processing methods should be adaptable and able to handle dynamic, multi-modal, heterogeneous and noisy and incomplete data.

− Future work on resource-aware data analytics, data discovery protocols and techniques, data combination, integration and mash-up and real world use-case implementations.
