Science of Big Data 2012 – Mark J. Headd – Big Data in the Big City


Mark Headd is the Chief Data Officer of the City of Philadelphia. The first official head of data in the city, he’s been working with other cities and with the city’s data science community to enable their work analyzing and visualizing data.

He shows open data being enabled by various governments and agencies, visualization tools that can show maps of data such as CartoDB.

He demonstrates crime statistics, service requests, twitter data, and historical data. He discusses data being released on crime statistics and license/inspection data, and how they may challenge open analysts to ask further questions. He then extrapolates what he’s learned and discusses how open data information may influence big data analysis.

Mr. Headd takes questions from the audience at the end of his presentation. Mark provides a number of applications that access open data at his GitHub account,
