align information operations by foreign actors seek to undermine the strategic interests
of the United States.
1
These operations, which are often orchestrated by authoritarian
regimes, are intended to manipulate the global information environment for geostrategic
purposes.
2
Such operations seek to shape public perceptions abroad by “creat[ing] propa-
ganda to undermine other nations’ national security.
3
The advent of advanced technologies and the
popularity of digital media platforms have increased the potential scale of these operations by allow-
ing malign entities to generate and distribute misinformation with increased efficiency and reach.
4
In addition to spreading false or misleading information, malign information operations often
employ broader forms of propaganda to shape narratives, shift public discourse, and undermine
other nations’ national security.
5
These operations often leverage classical propaganda techniques,
such as
name-calling, which attaches disparaging labels to opponents

资源描述:

这篇报告指出,外国恶意行为者通过信息战试图破坏美国战略利益,利用先进技术和数字媒体平台传播虚假信息、操纵全球舆论。俄罗斯和中国在信息战方面表现突出,其他国家和非国家行为体也采用类似策略。报告强调监测海外信息环境对美国国家安全至关重要,并介绍了多种检测宣传信息的方法,如社交网络分析、情感分析、立场分析等。研究发现,大语言模型(LLMs)在检测海外宣传方面具有潜力,通过对来自多个新闻媒体的文章进行测试,微调后的模型表现更佳,能有效识别宣传手段,但在区分宣传与非宣传内容时仍存在一定困难。未来研究可进一步完善检测
