The Free 'Big Data' Sources Everyone Should Know

I always make the point that data is everywhere – and that a lot of it is free. Companies don’t necessarily have to build their own massive data repositories before starting with big data analytics. The moves by companies and governments to put large amounts of information into the public domain have made large volumes of data accessible to everyone.

Any company, from big blue chip corporations to the tiniest start-up can now leverage more data than ever before. Many of my clients ask…

Data Veracity vs. Data Quality

There is often confusion between the definitions of "data veracity" and "data quality".

Data veracity is sometimes thought as uncertain or imprecise data, yet may be more precisely defined as false or inaccurate data. The data may be intentionally, negligently or mistakenly falsified. Data veracity may be distinguished from data quality,…

'Foresee' a Culture of Analytics

The years leading up to 2015 affirmed and reaffirmed that we indeed have lots of data. And with lots of data all around us, organizations should really be thinking about how to leverage data to get ahead not only of competition but to get ahead of everyday transactions and to be able to predict and control what's coming down the pike. Almost every transaction in society now is ‘datafied.' The automation and datafication of transactions and actions are giving us the opportunity to understand…

Digital Transformation impacting Customer journey

Digital transformation is omnipresent. It has already been changing our behavior as human beings.
More than ever, Customer expectations matter.  Don't like that app that you just downloaded?  You can give it a bad review.  No response from the developers means lost customers, or worse, going out of business. Such a bad customer experience posted on Twitter, Facebook and various other social media channels can be very detrimental to your…

At What Time in the Day Are We Most Productive?


When are you at your peak?​

It's 6:00am. Alarm clock's ringing. Begrudgingly you get up, throw on a pot of coffee, take a shower and are still moving slow as you are out the door and off to work. By the time we get to work, we feel that we are ready for the day. 

The other day, I found myself feeling exceptionally tired, not getting much work done even though it was 11:30 in the morning.…

The impact of asking the wrong question

For any data science project, if you start with the wrong question, you are bound to end up with the wrong answer, and fail. Who should identify the right question? I believe data scientists should be involved in the process, otherwise, they will be held responsible for the failure.

In the current blog, I will be briefly covering conceptual issues more focused on the nature of the structural data itself including its theoretical significance.

Structural data holds information about the relationship between events.…
