HBR: Theres an odds-on chance that someone in your organization is
making a poor decision on the basis of information that was
enormously expensive to collect Nate Silver: Our predictions may be
more prone to failure in the era of Big Data
- 6. Colin Strong, GfK, UK Big Data, 22 February 2013 Think like
a Bayesian Take into account the context through prior probability
Consider for level of false positives Probabilistic outcomes
Integrate multiple data sources

for Smart Data
- 9. Colin Strong, GfK, UK Big Data, 22 February 2013 1:
Individual case study Use digital data to collect information
concerning online behavior Integrate this with survey data to
understand the why Used successfully in purchase journey
analysis
- 10. Colin Strong, GfK, UK Big Data, 22 February 2013 2: Segment
case study Conducted segmentation of BT prospects database Overlaid
this with database of new customers Integrated with the tracking
studies to model the segmentation onto survey data Created a

Cultural analytics Analysis of massive cultural data sets and flows
Publically accessible data sets increasingly digitised allowing
much more access and analysis Ngram a leading tool, groups
