Data science used to predict crimes in Chicago

Victor Yip, Ilias Antoniou and Vladislav Ligay have built an interactive website to visualise and predict crimes in Chicago using data science. The team, comprised of students working towards an MSc Business Analytics at UCL http://busics.cs.ucl.ac.uk/, has built the prescriptive analytic tool with the aim of assisting the Chicago Police Force in mobilising patrol units.

With data from the Chicago Data Portal and Twitter, they were able to visualise the occurrence of crimes and tweets between 7 April & 12 May 2016.

They have trained a support vector machines model to predict likelihood of crime occurrence at a specific location and time, based on spatial, Twitter and natural language and temporal clues. The tool is offered online through an interactive website with a dashboard summarizing current crime situation in Chicago; and prediction overlying a map engine.

The team evaluated the models based on the “surveillance graph” - a plot of the proportion of crimes contained versus the proportion of city covered. The models with Twitter augmentation outperformed the baseline model without Twitter data. Titled ‘Crime Scene’, website can be found at

The trio have gone on to present the worl at UCL’s Centre for Advanced Spatial Analysis http://www.bartlett.ucl.ac.uk/casa.
