Is “big data” thinking based on developed economies appropriate for developing economies?

The New York Times carried a story on “big data for development” that featured Global Pulse, the UN initiative seeking to harness the potential of data to address development questions, much like what we are doing in our current research. The efforts by Global Pulse and a growing collection of scientists at universities, companies and […]

Predictive apps

It was one thing for Gmail to ask “did you intend to attach a document to this email?” based on your use of the word “attached” in the email. But it moves things to a whole new level when an app analyzes your digital bread crumbs and tells you stuff that you haven’t even thought […]

Metadata, transaction-generated information or Big Data

We were not quite ready to start talking about the privacy issues surrounding the massive amounts of data generated by telcos in the course of making it possible for people to communicate, but recent news events are accelerating the schedule. I thought it might be useful to start with this quote from someone I used […]

New thinking on privacy and data collection

Returning to the privacy field after a break of more than 10 years, I was struck by how inappropriate the old notice and consent approaches would be for what was actually happening on the ground. Here is an attempt to evolve new principles. Not had time to fully digest yet. Traditional approaches are no longer […]

Pentland on mobile big data

Alex Pentland of MIT has been working on mobile big data (as are we at LIRNEasia). Here is a snippet of an interview in the NYT: The phone tracks our movements, as well as our calls and texts, so it can reveal a lot about our daily lives. What did you learn about yourself by […]

Microsoft set to make big data capabilities commonplace

In the old days one needed supercomputers to analyze big data. American Express was the second largest customer for Cray after the NSA. Then you could do analysis on normal computer computers but with fancy software like T Cube. Now Microsoft plans on building these capabilities into Excel. Next year’s version of the Excel spreadsheet […]

Concerns about energy-use data

In 1992, I wrote parts of a report for the National Regulatory Research Institute in the US on privacy and competitive implications for transaction-generated information (a term that has been eclipsed by the less informative “big data” in recent times). We covered all utilities, including electricity. Burns,Robert; Samarajiva, Rohan & Mukherjee, Roopali (1992) Customer information: […]

Big business of big data

Acxiom does a lot more than just analyze streams of transaction-generated information (our definition of big data). But TGI is an important element of what does into Acxiom’s machines. Few consumers have ever heard of Acxiom. But analysts say it has amassed the world’s largest commercial database on consumers — and that it wants to […]

Why big data now?

I wrote about consumer transaction-generated information in the 1990s. Companies collected and analyzed data from sales points and loyalty programs. But it became sexy only recently. Why? It should not be too surprising that a Google-created entity should have this bent. Google, along with Web pioneers like Yahoo and Amazon, was crucial to the creation […]
