Introduction
We want to characterizing user behaviors in retweeting in Twitter. The objective of this project is to answer the question that, in Twitter, who often retweet from whom, and about what topics.
Team Members
Goal
Identifying the relationship between likelihood that a user retweets a tweet with some other network and linguistic factors, e.g., the relative position of the follower and the followee in the network (they are in the same political community or not), their centralities within the network and their communities, or the topic of the tweets, etc.
Methods
- Using bag-of-words based classifiers to identify user community label
- Using LDA based models to identify topics of the tweets
- Measuring user relative position in network using their community label and network centralities
- Measuring the relationship between the measures using their correlation coefficients, e.g, Pearson correlation
Dataset
The dataset has been crawled from Twitter using Twitter's APIs. Starting from a set of selected influential users, e.g., politician (barrackobama, mittromney, etc) and political bloggers (dailykos, ameriablog, etc) , we expanded the set by including their followers and followees. Tweets, including retweets, from all the users then will be crawled in daily basis. Roughly, we have 400K users, 7M tweets (about one-fifth are retweets) per month.
