因應近幾年的資訊爆炸，新聞媒體大量使用資料視覺化（Data Visualization）的新聞專題作為傳播的媒介，隨著媒體數位化，互動資料專題變成一個新興的載體幫助閱讀者去閱讀數據並發現數據中新的洞見、並用來說服閱讀者接受推廣的觀點，引發政治討論跟影響力。
本研究透過設計新的數據討論系統讓閱讀者可以更理性的基於討論數據進行討論，希望改善政治討論對風格，並透過文字探勘與主題分析來分析閱讀者對資料視覺化的看法。本研究落實於台灣線上政治討論場域，初步發現，透過數據備註與拆分的設計可以改善閱讀者的留言風格，讓留言內容更加理性、多元，希望提供未來在資料視覺化的討論互動設計上新的解決方法，以促進線上政治討論的討論良性發展，改善社會氛圍。

In response to the information overload in recent years, the news media used a lot of Data Visualization news as the medium. With the digitalization of the media, the interactive data visualization became an emerging medium to help readers read, discover data, new insights and use to convincing readers to accept the idea, therefore leading to political discussion and influence.

The study, through the design of a new data discussion system, allows readers to discuss more rationally based on discussion data, hoping to improve the style of political discussion, and analyze the reader's perception of data visualization through text exploration and theme analysis. This study was implemented in the online political discussion field in Taiwan. It was initially found that the design of data notes and splits can improve the reader's message style, make the message content more rational and diverse, and hope to provide future interactive design of data visualization, that develop better online political discussions and improve the social atmosphere.
