Smart City Data

− Data is multi-modal and heterogeneous− Noisy and incomplete− Time and location dependent − Dynamic and varies in quality − Crowd sourced data can be unreliable − Requires (near-) real-time analysis− Privacy and security are important issues

− Data alone may not give a clear picture

?

What happens if we only focus on data

− Number of burgers consumed per day.− Number of cats outside.− Number of people checking their facebook

account.

− What insight would you draw?

In Conclusion

− Smart cities are complex social systems and no technological and data- analytics-driven solution alone can solve the problems.

− Combination of 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 handle dynamic, multi-modal, heterogeneous and noisy and incomplete data.

− Effective visualisation and interaction methods are also key to develop successful solutions.
