I dropped out of university as a literature major in the 1980s.  (I needed time to find myself.)  Before I left, I read The Histories by the ancient Greek historian Herodotus.  I decided to name my new data object the Herodotus Event Data Object or HEDO.  A number of HEDOs can be stitched together to form codified narrative.  Those who follow my blogs might recall that I previously developed a system of codified narrative called BERLIN.  HEDOs represent my reinvention of BERLIN.  I…

Although RPA tools make significant strides, automating routine tasks and allowing humans to focus on more sophisticated ones, yet, they can’t adjust their procedures to self-execution without human help. On the other hand, there are natural language processing tools, with all their power to finally automate routine tasks.

Working in unison with RPA, artificial intelligence solutions “rethink” the ways companies…

If you've spent any time with modeling data, you'll know that there are many pitfalls to be had when it comes to data presentation (I addressed some common pitfalls in Misleading Graphs Part 1). Misleading graphs can be the result of incorrect data collection, ignorance of the basic "rules" of data presentation (like labeling axes), or even deliberate attempts to mislead. A fourth…

Data monetization is a hot topic these days.  Executives at both startups and large companies are being asked to capitalize on the value of their data assets and drive bottom line results.  According to McKinsey, in their paper "Fueling growth through Data Monetization", companies that invest in data monetization are outperformers in their category -- which is not surprising, given that application of data is highly…
