    • 摘要: 社交网络的日益普及和移动设备快捷的网络接入,使得网络舆情的传播十分迅捷,民众对热点话题的关注度和参与度得到很大的提升.网络舆情具有自由性、交互性、多元性、偏差性、突发性等特点,能够左右民众的情感和判断,能推动和改变事件的发展和走向,容易被反对分子利用,已经成为影响社会稳定的重要因素.因此,及时检测、控制并引导舆情的发展具有十分重要的意义.研究关注网络中传播的蕴含有“破坏”、“危险”、“损失”等涉及公共安全或涉及司法公正的行为.根据课题的需要,定义4种关注的异常行为类型:攻击行为、受伤行为、死亡行为、拘捕行为.从数据挖掘和信息抽取的角度研究识别异常行为的方法,首先通过分类器和触发词从海量的数据中过滤出包含异常行为的句子,然后抽取异常行为句中包含的命名实体,最后利用抽取的实体构建异常行为共现网络,为分析人员提供可视化的网络舆情分析方法.
