Beyond the 4 Ms of Manufacturing

The industrial revolution of the 1800s established the building blocks of Manufacturing as we know it today.

Social Media for App Capture and Question Answering in Open Vocabulary Executable English over Web Databases.

Imagine government and other web sites answering an open ended collection of English questions, and also explaining the answers in English.  Imagine people socially networking, Wikipedia-style, to continually expand the range of questions that can be answered.



The approach starts from the observation that data by itself is necessary, but not enough, for many practical uses of an intranet or the Web.



What's also needed is knowledge about how to use the data to answer an ever…

Common Pitfalls that Can Doom a BYOD Program

From what you hear from all the latest technology news, Bring Your Own Device (BYOD) is the end-all, be-all of technology policies, guaranteed to make businesses run smoother, employees feel happier, and cash pile up like never before. BYOD can certainly be helpful, but it’s far from the solution to all of a business’s problems, mainly because there are many pitfalls companies can easily fall into.

The NSA incurred the wrath of world leaders, the US Congress, and even a good portion of the American public when the…

If I have a database of sales figures spanning many years, I feel that I can become more aware of historic trends and seasonal patterns through the use of statistics. Statistics offers a sense of state, direction, pace, and progress. Statistics can also enable estimation…

This Just In: How Big Data is Changing Journalism

When people talk about journalists or reporters, the image of a man or woman eagerly talking to people with a notepad and pen in hand likely comes to mind. It’s a look that has permeated much of pop culture, but it should probably come as little surprise that the modern day journalist is much different. While they still may interview people on the street or sit down to talk with them, today’s journalist is turning to numbers, spreadsheets, and computer programs more often…
