Over the past six months we have been working with the reliability and maintenance organization within a large oil and gas client to build out their Master Equipment List (MEL). Like many asset-intensive organizations, they have implemented an Enterprise Asset Management (EAM) tool to give them visibility and control over their capital equipment to optimize their maintenance strategies, reduce operating costs, and better manage their workforce and spare parts inventories.

Having found a dataset on Ebola cases, thought of checking it out quickly what the statistics really look like.

The dataset contains 3 countries and within each there are multiple regions.

Is data science bad at detecting bogus Amazon or Yelp reviews?

There are lies, damn lies, and Amazon reviews. Why are so many Amazon or Yelp reviews bogus? Do they have bad data scientists who can't detect fraudulent reviews? No, they have unethical CEOs ready to do anything to make money short-term. And complaining about being unable to find real data scientists to solve their problems. This is a challenge for ethical data scientists who want to create value, but get punished by top management for not condoning their misdeeds.…

The end of the Data Scientist Bubble

This was the subject of a provocative article posted on Oracle's blog, two days ago. It certainly shows how far from the reality some big companies are.
