Yesterday Sriganesh and I had the pleasure of presenting LIRNEasia’s big data work at the 3rd session of the Colombo Big Data Meetup, a prominent local meetup group focusing on big data and data science, domains still very much in their infancy in Sri Lanka. We spoke to a diverse audience of nearly 150 IT professionals, academics, statisticians and enthusiasts. The presentation was followed by a panel discussion which included Sriganesh, Dr. Shehan Perera of the Computer Science Department of University of Moratuwa, and myself. The discussion touched on a range of topics including practical aspects of running a successful big data operation,  learning data science, democratization of data and collective privacy.
For many, daily travel is a product of routines that have been established over time. From commuting, getting the kids to school and back home to the occasional shopping trip much of our movements follow a predictable pattern. Attempts to map human movement in different regions across the world using emerging sources of big data such as mobile network call detail records (CDR) show that in general aggregate human movements change very little from one week day to another or from one weekend to another. Our work on human mobility using a large CDR dataset have shown that Sri Lanka is no different. However during some days of the year such as during festivals, holidays and natural disasters routine travel behavior gives way to unique travel behavior.
LIRNEasia’s ongoing big data research was recently presented at the 13th International Conference on Social Implications of Computers in Developing Countries held in Negombo from May 20-22. LIRNEasia researcher Danaja Maldeniya presented preliminary work on transport forecasting using  mobile network big data under the conference track ICT4D Sri Lanka : Challenges, Opportunities and Solutions. |paper|presentation slides|
