Social Media Data

What is NExT?

NExT is a Center jointly setup between National University of Singapore (NUS) and Tsinghua University. It received $10M funding in May 2010 from the Media Development Authority of Singapore (MDA) through the Interactive Digital Media Programme Office (IDMPO). With Prof Chua Tat Seng from NUS and Prof Sun Maosung from Tsinghua as the Co-Directors, the Centre focuses on research in “extreme search”, aiming at developing technologies to search for live and dynamic data beyond what is indexed in the current Web. In particular, the Center focuses on crawling and mining user-generated contents (UGC’s) in Singapore and Beijing. Click here for more details...

 

What is NExT Social Media Data?

As a part of the Live Observatory, NExT builds robust live crawlers to monitor and crawl data from several social media sites including Sina Weibo, Tencent Weibo, Twitter, Instagram, Foursquare, etc.. The User Generated Contents (UGCs) we crawled include text, image, location-oriented UGC, as well as user, annotation and other structured information. For legal reasons, the data can only be used internally for research purposes.

 

How much data?

As of 18 Jun 2013, we have archived a total of over 1.8 billion clean data records including 276 million images and 92,484 videos. We started our crawling effort since May 2012. Please refer to our  Live Crawler for more details on the data size.
