首发时间:2020-03-23
摘要:对涉诉信访处理不当可能会引发社会冲突和危害公共安全,对其进行风险预警是维护社会稳定的重要途径之一,建立可靠的涉诉信访风险预警机制具有重大意义。应用数据挖掘技术分析涉诉信访的风险防范策略,针对搜集到的上万条五省市法院裁判文书数据进行抽象提取出关键信息,将整理得到的不同维度数据作为特征,再邀请法学专家对已有文书数据进行涉诉信访风险标注。通过随机森林算法训练所得标准化数据,构建了涉诉信访风险预警模型,用于对新产生的文书数据进行风险预警。经实验验证,该模型风险预测准确率达到88.10%,可有效应用于涉诉信访风险的预警机制中,为创建智慧法院起到积极的推动作用。

Risk early warning model of complaints and petitions based on random forest algorithm
Abstract:Improper handling of complaints and petitions may cause social conflicts and endanger public safety. It is important to maintain social stability to provide risk early warning. It is of great significance to establish a reliable early warning mechanism of complaints and petitions. Data mining techniques were applied to analyze the risk prevention strategies of complaints and petitions, and key information was extracted from the Risk early warning model of complaints and petitions based on random forest algorithmcollected tens of thousands of judgement documents in five provinces and municipalities, then sorted out different dimensions of data as features, then invited legal experts to mark the risk of complaints and petitions based on existing documents. Then a risk early warning model was constructed by training normalized data through random forest algorithm, which was for risk warning of newly generated judgement document data. The experimental verification shows that the model\'s risk prediction accuracy rate reaches 88.10%, which can be effectively applied to the early warning mechanism of the complaints and petitions risk. It as well as will play a positive role in promoting the creation of a smart court.
