318運動是臺灣社會罕見以占領國會議場表達訴求的抗爭運動，同時也是大規模群眾透過傳播科技的中介即時參與網絡化社運，包括在社交媒體分享即時新聞、上傳現場目擊照片、創作歌曲在Youtube流傳，甚至透過直播科技24小時不間斷地轉播占領現場狀況。為了瞭解此一運動的樣貌，本研究選取Twitter做為資料收集平臺，藉由社交媒體鉅量資料的即時收集與事後分析，探討臺灣318運動期間Twitter各種語言相關推文（tweets）的趨勢變化，研究發現當運動發生直接衝突時，公民目擊及直播頻道會帶來瞬間大量的訊息擴散，另外透過超連結分析發現，公眾透過在社交媒體轉發或評論即時新聞，做為即時參與運動的另一種形式。

The 318 movement is a rare case of large-scale occupy movement in Taiwan. It is also a highly networked movement as its participants were mobilized and coordinated by the use of communication technologies including instant sharing of eyewitness photos and news as well as live streaming videos of the occupied sites on social media. To better understand this movement, this study analyzes tweeting extracts from the participants in the movement on Twitter. It was found that when clashes between the protesters and the opposing forces took place, eyewitness accounts and live streaming instantly brought about a massive diffusion of information. Furthermore, the hyperlink analysis conducted in this study suggests that spreading or commenting on the instant news is an alternative way for the public to participate in the movement.
