摘要

本論文採用反謠言擴散的方法來反制謠言在社群網路上擴散。我們所提出的反謠言擴散模型是要求反謠言訊息接收者挑選一位朋友，接著以通知方式取代盲目分享方式，將反謠言訊息傳遞給該朋友，我們稱此朋友為「反謠言訊息傳遞者」。根據接收者與其朋友的關係，我們提出了四種挑選下一個反謠言訊息傳遞者的方法，分別是random、min-degree、max-degree、與less-common-friends。
我們依據所提出的模型重複進行多次的模擬實驗，實驗結果顯示：
(1) less-common-friends反制謠言的效果優於其它方法。(2) 社群網路的大小並不會影響反謠言訊息擴散的效率。(3) 隨者小世界網路隨機連結機率的增加，反謠言訊息擴散的效率將會越差。(4) 當社群網路中的平均朋友數量增加時，反謠言訊息擴散的效率也將會越差。

This thesis uses the approach of spreading an anti-rumor to combat a rumor spread in a social network. In the proposed model, instead of blind sharing anti-rumors, the receiver is forced to forward anti-rumors to one of his/her friends, who is named an anti-target. This study proposes four strategies: random, min-degree, max-degree, and less-common-friends, according to the friendship of the receiver with others, for determining the next anti-target.
A simulation experiment is conducted based on the proposed model and the same experiment is repeated for many times. The experiment results show that: (1) the strategy of less-common-friends can combat the rumor more effectively than the other strategies; (2) the size of social network will not affect the efficiency of spreading anti-rumors; (3) when the probability of rewiring links in a small network becomes larger, it will lead to less effectively in spreading anti-rumors; (4) when the average number of friends in the social network is increased, it will lead to less effectively in spreading anti-rumors.
