面對數位語藝具有「互動性」與「互文性」特質，形成龐大的網路文本量。本研究以反核臉書粉絲團為例，對照運用大數據分析與人力瀏覽、編碼方式，進行幻想主題分析。歸結論證採取大數據文本探勘工具有利於確認相關被「覆誦」的關鍵字，並發現在主、回文的語意共現情形，出現意義展延現象，更加鞏固「幻想主題」及「語藝視野」。本研究建議，面對數位語藝環境，可善用文本探勘工具，確認文本中實然被「覆誦」的語彙，再加以論證、詮釋；再選取具有代表性小樣本進行人力瀏覽、編碼，確證分析與補充，俾利擴大語藝批評的實用性。

The rhetorics in the digital world demonstrate interactivity and intertextuality, generating the massive volume of internet texts. This study takes on the subject of an anti-nuclear Facebook channel. The computer text mining tool is used to determine and analyze the keywords that are chained out in the text. The rhetorical collocation of the main entries and responses is found having extension of meanings; through them, the fantasy themes and rhetorical vision are further strengthened. In conclusion, this study suggests that the text mining tools may be better utilized in the digital world to confirm and further demonstrate the keywords that are chained out in the text. Moreover, representative samples may be selected to conduct manual browsing and coding and confirm the analytical results and to rectify any weaknesses, thereby expanding the usability of rhetorical criticism.
