This article relies on information-theoretic measures to examine how events impacted the news for the period 1950-1995. Moreover, we present a method for event characterization in (unstructured) textual sources, offering a taxonomy of events based on the different ways they impacted the flow of news information. The results give us a better understanding of the relationship between events and their impact on news sources with varying ideological backgrounds.

事件流——事件如何塑造新闻流，1950-1995

本文依靠信息论测量来研究事件如何影响 1950 年至 1995 年期间的新闻。此外，我们提出了一种在（非结构化）文本源中进行事件表征的方法，根据事件影响新闻信息流的不同方式提供事件分类法。结果让我们更好地了解事件之间的关系及其对具有不同意识形态背景的新闻来源的影响。
