用新闻文本和变换器模型预测冲突各方的动态变化。

From Newswire to Nexus: Using text-based actor embeddings and transformer networks to forecast conflict dynamics

  • 融合新闻文本与结构化事件数据,构建冲突动态预测框架。
  • 在历史事件上回测表现优异,显著超越传统模型。
  • 适合政策制定者、人道组织用于干预策略制定。

本研究通过结合新闻文本与结构化冲突事件数据,利用自然语言处理技术中的变换器模型,在行为体层面预测暴力冲突的动态演变。研究基于乌普萨拉冲突数据项目的手工标注事件数据,构建并标注了大规模国际新闻语料库,使模型能够融合新闻文本语境与结构化数据的精确性。该方法实现了对政府、民兵、分离主义运动及恐怖组织等冲突方之间冲突升级与降级的动态、细粒度预测。通过严格的回溯测试验证,模型展现出优异的样本外预测能力,显著优于传统方法。研究旨在为政策制定者、人道组织与维和行动提供可操作的洞察,支持精准干预策略的制定。

原文摘要 · Abstract (English)

This study advances the field of conflict forecasting by using text-based actor embeddings with transformer models to predict dynamic changes in violent conflict patterns at the actor level. More specifically, we combine newswire texts with structured conflict event data and leverage recent advances in Natural Language Processing (NLP) techniques to forecast escalations and de-escalations among conflicting actors, such as governments, militias, separatist movements, and terrorists. This new approach accurately and promptly captures the inherently volatile patterns of violent conflicts, which existing methods have not been able to achieve. To create this framework, we began by curating and annotating a vast international newswire corpus, leveraging hand-labeled event data from the Uppsala Conflict Data Program. By using this hybrid dataset, our models can incorporate the textual context of news sources along with the precision and detail of structured event data. This combination enables us to make both dynamic and granular predictions about conflict developments. We validate our approach through rigorous back-testing against historical events, demonstrating superior out-of-sample predictive power. We find that our approach is quite effective in identifying and predicting phases of conflict escalation and de-escalation, surpassing the capabilities of traditional models. By focusing on actor interactions, our explicit goal is to provide actionable insights to policymakers, humanitarian organizations, and peacekeeping operations in order to enable targeted and effective intervention strategies.
