在經歷過2016年美國總統大選、英國脫歐、關西機場事件之後,我們的社會開始大量關注「假新聞」這個議題,在意假新聞所帶來的危害,以及對於解方的尋求。要解決假新聞的問題,我們必須先瞭解假新聞從何而來,一般來說,假訊息經過跨平台的轉傳之後,難以追查最起始的源頭訊息,但是我們可以確切知道的是這些訊息多半會經過「內容農場」這樣的網站,經過分享、轉傳到各大社群平台或是通訊軟體之上。「內容農場」經過網域的轉換,更改名稱之後,又會再一次的出現在閱聽眾的眼前,就像是不易徹底清除且易於繁殖的病毒,那我們是否可以用教育來遏止假新聞的傳播?

人工智慧的出現與大數據的資料處理,為我們提供了技術上的協助,本研究參照以我國中央研究院的CKIP系統以及大量新聞資料作為依據,輔以DNN深度學習所製作出的新聞可信度的判別系統來設計實驗課程,希望更有效率的幫助閱聽人判別訊息,提供閱聽人在判別訊息時有一個評判的依據。本研究期望暸解,當閱聽人採用該系統作為輔助工具之後,「媒體素養」的相關認知與態度是否有顯著正面的提升,期望能夠在假訊息充斥的時代,為閱聽人提供一種額外的方式,避免受到假訊息的影響,進而維繫得來不易的民主社會。

After the 2016 U.S. presidential election, Brexit, and the Kansai Airport incident, our society has begun to pay huge attention to the harm caused by "fake news," and to search for solutions. "Media literacy" has been known as a way to solve this problem. In this research, the researchers tries to realize people who use the system by artificial intelligence will improve their attitude towards media literacy or not.

The system is based on the CKIP system which serves as a natural language processor from Taiwan Academia Sinica and integrates a large amount of news database, including messages from regular media, content farms as well as the artificial intelligence produced by DNN . 

In this experiment, the lesson was designed and based on media literacy but only the experiment group used the system as an auxiliary tool to distinguish fake news from real ones. After that, we find out the attitude of learning media literacy and checking the information have more positive attitude compared to the control group, and their performance of identifying messages as well.

This study aims to understand whether the cognition and attitude related to "media literacy" will be significantly improved after the audience uses the system as an auxiliary tool. It is hoped that it will provide an additional benefit for the audience in the era of “post-truth”. this is the only way to avoid the influence of false information and further establish an advanced democratic society.
