What is Big Data?
Big data is being generated by everything around us.
Every digital process and social media exchange produces it.
Systems, sensors and mobile devices transmit it.
Big data is arriving from multiple sources at amazing
velocities, volumes and varieties.
To extract meaningful value from big data, you
need optimal processing power, storage,
analytics capabilities, and skills.

Why do data scientists want more data, rather than less?
It is there.
Data is the basis of the models we create to explain, predict,
and affect behavior.
With more data, our models become more sophisticated
and, we hope, more accurate.
How much data is too much data?

What issues can analytics present?
Are all aspects of privacy, anonymization, and liability
understood by the practitioners?
If I tell you that you cannot look at some data but you can
infer the information (e.g., gender) anyway, is that all right?
What are the rules for working with metadata and
summarized data?
How do we process static, collected data together with more
real-time, rapidly changing information such as location?

Approach to policy can determine outcomes
Reductions in the amount and kinds of data can produce
diminished or inaccurate results.
Policy must take into account the value received by individuals
for the use of their personal data.
Enforced data localization may decrease
analytical completeness unless we can
move intermediate results or the site of
computation.
