Dear AOIRers, We are delighted to make open access our Chinese weibo data collected in 2012 (over 226 million Chinese microblogs). The dataset consists of a large amount of deleted and censored posts that are no longer available in the public domain. For ethical reason, all data are anonymized, i.e. real user and message id are replaced by pseudo ID. http://147.8.142.179/datazip/ "Weiboscope" is our project name and is a social media data collection, visualization, and analysis project developed by the Journalism and Media Studies Centre, The University of Hong Kong (HKU). The project is funded by the HKU's Seed Funding Program for Basic Research. Please cite the below paper when using the data. King-wa Fu, CH Chan, Michael Chau.
