论文摘要
大多数人认为他们的朋友比自己更积极，表现出情感悖论。心理学研究将这种悖论归因于人类认知偏见。为了了解这种现象，我们研究了社交网络中的情感悖论。我们的工作表明，用户的社交联系（朋友，关注者或追随者）确实比用户自己更积极。这主要是由于积极的用户有更多的朋友。我们在不同的网络层面上确定了五个情绪悖论，从三合会到大型社区。提供了经验和理论证据，以验证这种情感悖论的存在。通过调查情感悖论与其他发达的网络悖论（即友谊悖论和活动悖论）之间的关系，我们发现用户的情感与他们的朋友数量呈正相关，但很少与他们的社交活动相关。最后，我们证明了如何使用情感悖论来预测用户的情感。
Most people consider their friends to be more positive than themselves, exhibiting a Sentiment Paradox. Psychology research attributes this paradox to human cognition bias. With the goal to understand this phenomenon, we study sentiment paradoxes in social networks. Our work shows that social connections (friends, followees, or followers) of users are indeed (not just illusively) more positive than the users themselves. This is mostly due to positive users having more friends. We identify five sentiment paradoxes at different network levels ranging from triads to large-scale communities. Empirical and theoretical evidence are provided to validate the existence of such sentiment paradoxes. By investigating the relationships between the sentiment paradox and other well-developed network paradoxes, i.e., friendship paradox and activity paradox, we find that user sentiments are positively correlated to their number of friends but rarely to their social activity. Finally, we demonstrate how sentiment paradoxes can be used to predict user sentiments.
