Wired UK, Barabási Lab and BIG data. Over the last year, I’ve produced five data-driven pieces for Wired UK. Four of them have been for the two-page infoporn spread that can be found in every issue. I’ve looked at the UK’s National DNA Database, used mined Twitter data to find people’s travel paths, and mapped traffic in some of the world’s busiest sea ports. In the August issue, out on newsstands right now, I had a chance to work with some spectacular data and extremely talented people.
The piece looks at a very, very big data set – cellular phone records from a pool of 10 million users in an anonymous European country. In this post, I’ll walk through the process of creating this piece. Working With Big Data I can’t get into a lot of detail about the specifics of the data set, but needless to say, phone records for 10 million individuals take up a lot of space. The first thing I did with the trimmed-down data was to construct ‘call histories’ for each user in the set.
