多模态风险事件存证数据集

本数据集主要面向社会风险存证相关研究需求建设。数据集基于国内外主流新闻媒体、社交网络平台及政府公开数据资源等多源信息渠道采集生成，通过多源协同获取方式系统收集社会风险事件相关的图像、文本、音频和视频等多模态数据。该数据集主要记录了多类典型社会风险事件在不同模态下的表现特征，形成标准化实验样本库，为社会风险事件的可信存证提供数据支撑。This dataset was constructed to meet research requirements for social risk evidence preservation. It is collected from multi-source information channels including mainstream domestic and international news media, social networking platforms, and government open data resources. Through a multi-source collaborative acquisition approach, the dataset systematically gathers multimodal data such as images, texts, audios and videos related to social risk events. This dataset mainly records the manifestation characteristics of various typical social risk events across different modalities, forming a standardized experimental sample repository, and provides data support for credible evidence preservation of social risk events.
