用对话点结构分析新闻中的意识形态叙事,提升对舆论核心的把握。
Talking Point based Ideological Discourse Analysis in News Events
- 构建对话点关系结构,捕捉实体、角色与媒体框架间的互动。
- 识别重复主题形成显著对话点,生成具有立场特征的观点。
- 可生成事件话语快照,适合研究政治舆论与媒体偏见者使用。
在大语言模型时代,分析意识形态话语仍具挑战,因这些模型难以聚焦塑造现实叙事的关键要素,且缺乏整合上下文理解抽象意识形态观点的能力。为此,我们提出一种基于意识形态话语分析理论的框架,用于分析真实事件相关的新闻文章。该框架将新闻文章表示为一种关系结构——对话点,捕捉实体间互动、角色定位、媒体框架与讨论话题之间的关联。在此基础上,构建重复出现的主题词汇表——显著对话点,进而生成具有特定意识形态倾向的观点(或党派视角)。通过自动化任务(意识形态与党派分类)并辅以人工验证,评估该框架生成观点的能力。此外,我们展示了该框架在生成事件快照(可视化解读事件话语)方面的直接应用。我们已公开数据集与模型,以支持后续研究。
原文摘要 · Abstract (English)
Analyzing ideological discourse even in the age of LLMs remains a challenge, as these models often struggle to capture the key elements that shape real-world narratives. Specifically, LLMs fail to focus on characteristic elements driving dominant discourses and lack the ability to integrate contextual information required for understanding abstract ideological views. To address these limitations, we propose a framework motivated by the theory of ideological discourse analysis to analyze news articles related to real-world events. Our framework represents the news articles using a relational structure - talking points, which captures the interaction between entities, their roles, and media frames along with a topic of discussion. It then constructs a vocabulary of repeating themes - prominent talking points, that are used to generate ideology-specific viewpoints (or partisan perspectives). We evaluate our framework's ability to generate these perspectives through automated tasks - ideology and partisan classification tasks, supplemented by human validation. Additionally, we demonstrate straightforward applicability of our framework in creating event snapshots, a visual way of interpreting event discourse. We release resulting dataset and model to the community to support further research.
