中文新聞文本之宣傳手法標記與分析

The Analysis and Annotation of Propaganda Techniques in Chinese News Texts

新聞媒體常在政治新聞文本中運用宣傳手法（propaganda techniques）表達媒體本身之政治立場，企圖影響讀者之立場。目前尚無具宣傳手法標記之中文語料供立場分析，本文以考量可解釋性的方式，人工細部標記中文新聞文本所使用之宣傳手法、並以Bootstrap方式擴展標記規模的資料集，最後再人工校正確保標記之品質。本宣傳手法之人工標記資料已公開釋出，可應用於未來機器訓練與學習預測新文本之立場。

In political news media, propaganda techniques are often employed to express one's political view, or to influence the audience's stance. Chinese corpora with the annotation of propaganda techniques are yet to be developed. In this paper, with an explainable approach we annotated the use of propaganda techniques in Chinese political news texts, and enlarged the dataset by bootstrapping using a small set of manually annotated data. We also manually corrected the bootstrapped dataset to increase the data quality. The data manually annotated with propaganda techniques is available online for the application of machine training and learning to predict the stance of new texts.
