基于角色嵌入的Reddit网络时序分析

Temporal Analysis of Reddit Networks via Role Embeddings

Insight Centre for Data Analytics(洞察数据分析中心)

Siobhan Grayson, Derek Greene

摘要:

受自然语言处理领域的历时词分析的启发,我们提出了一种使用图嵌入方法从社交网络中揭示用户角色的时间洞察的方法。具体来说,我们应用的角色嵌入算法,struct2vec,收集社交网络展示来自流行的在线社交新闻聚合网站Reddit的“忠诚”或“流浪”的特点。对于每个subreddit,我们提取9个月的数据,并在连续的时间窗口上创建网络角色嵌入。然后,我们能够比较和对比用户角色如何随着时间的推移而变化,通过调整产生的时间嵌入空间。特别是,我们从个人和社区层面的角度分析了Reddit上忠诚和流浪社区的时间角色嵌入。

英文摘要:

Inspired by diachronic word analysis from the field of natural language processing, we propose an approach for uncovering temporal insights regarding user roles from social networks using graph embedding methods. Specifically, we apply the role embedding algorithm, struc2vec, to a collection of social networks exhibiting either "loyal" or "vagrant" characteristics derived from the popular online social news aggregation website Reddit. For each subreddit, we extract nine months of data and create network role embeddings on consecutive time windows. We are then able to compare and contrast how user roles change over time by aligning the resulting temporal embeddings spaces. In particular, we analyse temporal role embeddings from an individual and a community-level perspective for both loyal and vagrant communities present on Reddit.
