Social disruption events can be modelled by time series and are influenced by other event series (local, neighbour cities and the major cities), posts in social media, news, and economic circumstance, etc. The extracted information from the media forms features (Ramakrishnan et al 2014). Each feature is represented as a time series, and the data is a large set of time series. The aim of the project is to select a subset of time series that are informative for the prediction the future civil unrest events. Some feature selection work of time series can be found in (Kim 2012; Sun et al 2014).

Requirements
