Tweet Collections P. Pond, G. Prevost, N.R. May Download data as .tar

This experiment contains collections of tweets captured at the time of the 2011 UK Riots. The data provides a historical record of public discussion on Twitter during a significant social happening. It also represents a useful resources for experimentation and methodological development. The data is both a social and an informational resource, enabling the analysis of a significant social event and the development/application of computational tools for, among other aims, natural language processing, information retrieval, meta data analysis. In addition to the principle collection of tweets (UK Riots Database), a sub-collection has been extracted that includes only the geo-tagged tweets. Finally, these databases are stored on MongoDB and are made queryable using a special interface (see the UK Riots Database for access and instructions) that allows queries to be stored in another dataset, shared, and re-executed.

This experiment contains a dataset that represent collections of courier trajectories, captured principally around London over a continuous eight week period. This is a useful example of real movement trajectories, which could potentially be used for benchmarking or for the development of spatio-temporal analytics. In addition to the principle data file,which contains 9,917,703 discrete data points, sixteen different spatial and temporal summaries have been included in this experiment to aid analysis.
