这应该是第一篇(?)专业研究八卦版带风向的文章
9/10才刚刊出 作者是来自 中研院统计科学研究所 的团队

摘要落落长 直接贴结论
Conclusions
Using the PTT gossiping data, we have found some interesting findings for the
effect of social influence on users’ decisions on showing approval or
disapproval towards posted messages. We see that as long as decisions are
made in a sequence and observable, individuals tend to use this information
to help them make their choices.
作者研究了PTT八卦版的data后，发现了风向的重要性。
一篇文章出来后，乡民们会先看看其他人是推或嘘，再来来决定自己的意见。
Our results suggest that such influence occurs at the local level, implying
on-line users tend to adopt such information to conform to the majority of the nearby individuals. Moreover,
when more local information is available, its impact also increases.
简单来说，就是大家会跟着风向走；风向越强越多人跟着风向走。
Interestingly, even in an anonymous environment where individuals are unknown
to each other, there is still a tendency for everyone to follow the present
popular trend. If previous information is not revealed to users such that
they have little idea on what others have been doing, then whether social
influence still plays a role in users’ behaviour in an on-line community
remains an elusive question and experiments need to be conducted to
investigate this issue.
有趣的是，就算是在匿名，不知道id背后是谁的情况之下也是这样。
Moreover, the global and local measures in our models assumed independent
effects and each comment has an equal weight. In reality, some users
may be perceived to be more important (or more prestigious) than others
in a community, and their comments may consequently influence others
more strongly.
研究假设每个id的意见的影响力是相同的，但事实上有些id的影响力特别大，
带风向的能力特强，就是领头羊这样。
All these can be interesting questions and give directions to future research
on this particular topic.
更多的研究还在进行中...
心得:
真的不简单 我看八卦版只能浪费生命而已 竟然有人可以发篇期刊
看来以后研究生在实验室看八卦板 有新的借口了
