Connections between users in the AAS221 tweet stream

This is preliminary data and is subject to change. Please contact me if you have questions. Connections between users who tweeted about the AAS 221 conference (well, those tweets that included 'aas221', 'hackaas', or 'aas' and '221') in January 2013. The file aas221.sif is a directed graph of links from the user who made the tweet (first column) to user they mentioned in the tweet (third column), which includes 'RT @user ...). The second column is the number of times this happened. The file is tab separated and is intended for use in BioFabric. The file aas221.communities.tsv is also tab separated, and lists the community number (starting at 1) for each pair of users mentioned in aas221.sif. This was created using the algorithm of Ahn, Bagrow, and Lehmnan (doi:10.1038/nature09182), and assumes the links are unweighted and undirected.本数据集为初步数据，后续可能进行调整。如有疑问，请与我联系。该数据集记录了2013年1月期间，在Twitter平台发布提及AAS 221会议推文的用户之间的关联关系；此处提及的推文需包含"aas221"、"hackaas"，或同时包含"aas"与"221"关键词。文件aas221.sif为有向图（directed graph）格式的关联数据，记录了推文发布者（第一列）到其推文中提及用户（第三列，包含"RT @user ..."格式的提及）的链接关系，第二列则为该类关联的发生次数。该文件以制表符分隔，专为BioFabric工具设计使用。文件aas221.communities.tsv同样采用制表符分隔格式，其中列出了aas221.sif中每一对用户对应的社区编号（编号从1开始）。该社区划分结果基于Ahn、Bagrow与Lehmann提出的算法（doi:10.1038/nature09182）生成，且假设关联关系为无权重且无向的。
