微博话题讨论与关键用户识别研究

微博话题讨论与关键用户识别研究(中文3000字,英文2000字)
技术背景
    随着在线社交工具的快速发展，出现了一种新型OSN微博。微博是一种新的范例应用程序，它更加快速和灵活，将消息的长度限制为140个字符。除了这些文本特征之外，它还带来了一种新的社会关系，即所谓的单向跟随机制，这意味着可以在没有该人的确认的情况下跟随一个人。这样，与之前的OSN如Facebook和Flickr相比，它构建了一个相对宽松的社会关系。
Twitter作为全球第一个微博网站，是微博时代的开始。它减少了编辑漫长博客的难度，但为人们提供了一个创建简单短消息并与其追随者分享的平台。此外，人们可以转发或评论他人的帖子，从而与他们的朋友互动。此外，用户可以讨论他们感兴趣的某些主题，例如格莱美奖，Sherlock等。

A Research on Topic Discussion and Key User Identification in Microblog
A. Technical Context
A new type of OSN—microblog has emerged as the rapid development of online social tools. Microblog is a new paradigm application that is more instant and flexible, which restricts the length of the message into 140 characters. Besides these text characteristics, it also brings a new kind of social relationship, the so-called unidirectional following mechanism, which means one can follow one person without the confirmation of that person. In this way, it constructs a relatively loose social relationship compared with previous OSNs, such as Facebook and Flickr.
