We have been very busy creating a set of unique Twitter data samples for the fake news student detection challenge. There are new collections of bot-mentioning Tweets, also by users with >100,000 followers, other influencer segments, top RT segments, and a 1.1 million item sample representing the seed of every duplicate group in the original 20 million Tweet collection. To learn about the metadata enhancements that make this and the influencer segments valuable, we have prepared a short video. Watch the video below to learn more about the free student data challenge and to get tips on why the best data samples are in fact great tricks for doing other kinds of important social media research. New teams are still getting organized. Write to email@example.com for more information. The deadline for submissions is April 1, 2017.
