新聞來源引用向來是傳播研究重要課題，本文主要探討社交媒 體對新聞來源之引用，以2012 年台灣總統大選期間在Twitter 上的 討論為例，透過網址還原技術（URL unshorten）的應用，解析社交 媒體大量貼文內含的超連結之來源分布，比較台灣、中國、香港、 日本新聞媒體被引用的情況。本研究透過資訊技術與傳播研究結合， 開發社交媒體之探勘技術，藉此瞭解新聞媒體與社交媒體之互動關 係，以及新聞產製者及消費者在不同情境下的社交媒體策略。

News sources are critical in communication studies. Analyses of news sources cited by social media users enable understanding the relationship between the public and news reporting. This study focused on the citation of news sources in social media. Using the URL unshortening technique, we analyzed the contents of hyperlinks in tweets sent during the 2012 Taiwan presidential election. We compared the patterns of social media citation among news agencies in Taiwan, China, Hong Kong, and Japan. We also identified the most cited Taiwanese news source on Twitter. This study combined computational technology and communication studies to develop a novel technique for exploring how social media interact with traditional mass media.
