This document discusses data analytics for smart cities. It describes how large volumes of data from sources like traffic, weather, and social media can be analyzed to provide insights and improve city management. However, ensuring privacy, security, and that citizens remain in control of their data is challenging. Open data standards and complementary datasets are also needed to fully understand events. Overall, data analytics enables new smart city applications but also raises issues that must be addressed regarding data quality, context, and governance.

8. Smart City Data Analysis
− Analysis of thousands of traffic, pollution, weather, congestion, public
transport, waste and event sensory data to provide better transport and city
management.
− Converting smart meter readings to information that can help prediction and
balance of power consumption in a city.
− Monitoring elderly homes, personal and public healthcare applications.
− Event and incident analysis and prediction using (near) real-time data
collected by citizen and device sensors.
− Turning social media data (e.g. Tweets) related to city issues into event and
sentiment analysis.
− Any many more…

9. Smart City Data
− Data is multi-modal and heterogeneous
− Noisy and incomplete
− Time and location dependent
− Dynamic and varies in quality
− Crowed sourced data can be unreliable
− Requires (near-) real-time analysis
− Privacy and security are important issues
− Data can be biased- we need to know our data!
− Data alone may not give a clear picture -we need contextual information,
background knowledge, multi-source information and obviously better data
analytics solutions…

− Smart Data Collection
− Intelligent Data
Processing (selective
attention and information-
extraction)
− Region Beta Paradox

21. Data Analytics for Smart Cities
− Great opportunities and many applications;
− Enhanced and (near-) real-time insights;
− Supporting more automated decision making and in-
depth analysis of events and occurrences by combining
various sources of data;
− Providing more and better information to citizens;
− …

22. However…
− We need to know our data and its context (density,
quality, reliability, …)
− Open Data (there needs to be more real-time data)
− Complementary data
− Citizens in control
− Transparency and data management issues (privacy,
security, trust, …)
− Reliability and dependability of the systems
