摘要

背景：报纸专栏文章是一种未被充分探索的传播模式，它涵盖了社会、文化和政治问题。分析：本文使用一种称为结构主题建模的无监督机器学习方法，绘制了加拿大报纸关于信息自由法的专栏文章语料库内容在20年期间的变化。这就有可能调查报纸专栏文章内容随时间的变化，并解读国家、地区和地方报纸发表的主题的趋势。结论和启示：使用计算方法分析新闻文本，并为未来信息自由和政治传播的研究提供建议。

Deciphering the Decline: A Computational Analysis of Two Decades of Canadian Newspaper Op-Eds on Freedom of Information

Background: Newspaper op-eds are an underexplored mode of communication that frame social, cultural, and political issues. Analysis: This article uses an unsupervised machine-learning approach called structural topic modelling to map changes in the content of a corpus of Canadian newspaper op-eds on freedom of information (FOI) law spanning a 20-year period. This makes it possible to investigate changes in the content of newspaper op-eds over time and to decipher trends in the kinds of topics that national, regional, and local newspapers publish. Conclusion and implications: Computational approaches to analyzing news texts are used, and recommendations are offered for future research on FOI and political communications.
