In the first ever English Episode of UNF#CK YOUR DATA host
Christian Krug interviews Susan Walsh, the classification guru,
on how to clean your dirty data.
But firstly, what is dirty data and why does this pose a problem?
Data in your company systems, like CRM or ERP, can have all sorts
of issues. Duplicates, near duplicates, formats and so on.
So the records which should match, don’t. Or your numbers are
off.
Basically, you can’t rely on the data in the system to make
decisions. Like sending a mail or a leaflet. Potentially even an
invoice. Or know who your real number one customer is.
To help you deal with this mess, Susan has created a framework,
which helps you cleaning up your data. You have to normalize and
classify your data. First agree on a common format an fit the
data to it. Afterwards you can give the data a meaning by
classifying it.
So you can further process the data and base your decisions on
it.
Sad news for all the AI enthusiasts out there: This still
requires an awful lot of human knowledge. No speeding up the
process.
On the other hand this step is crucial for your AI success. As
only good quality training data will lead to great AI results.
Regardless, which use case you tackle first.
But cleaning data one is not a lasting solution. It’s a
continuous effort and it hast to start at the very source where
people enter the data into the systems.
So data quality is a process and mantra.
