Prediction of network public opinion features in urban planning based on geographical case-based reasoning

引用

International Journal of Digital Earth 2022年第1期15卷 890-910页

作者： Rui Li Jingqi wang shunli wang Huayi Wu State Key Laboratory of Information Engineering in Surveying Mapping and Remote SensingWuhan UniversityWuhanPeople’s Republic of China Hubei Luojia Laboratory WuhanPeople’s Republic of China Collaborative Innovation Center of Geospatial Technology WuhanPeople’s Republic of China

As a significant part of sustainable urban development proposed by the United Nations,urban planning is related to the ecological environment and transportation,especially affecting quality of life and social well-being. In the process of urban planning,the public express their opinions on open network platforms,resulting in large quantities of network public opinion data,which has important implications for evaluating urban planning. Based on the idea of geographical case-based reasoning (CBR),this paper constructs an expression framework for urban planning cases in the form of a ‘case problem–case attribute–case result’ triad. On this basis,this paper proposes a similarity calculation method of urban planning cases that integrates case attribute. Finally,based on an improvement to the traditional k-nearest neighbors method,the proposed public opinion feature calculation model considers similarity weights,which allow us to predict network public opinion features,including viewpoint-level emotional tendency and concerned groups of urban planning cases. The experimental result shows similarity weights (SWs) model could effectively improve the prediction accuracy,where the average MIC-F1 score reached more than 74%. Based on CBR,the proposed method can predict the development trends of public opinion in future planning cases,and provide scientific and reasonable decision support for urban planning.

随着焊接技术的不断发展,越来越多的箱体类零件采用焊接方式初加工,再由机床精加工,精加工时,通过增加内部支撑装置防止零件加工时产生变形。对于高度较小且深度较大的箱体类零件,如高度小于300 mm、且深度大于1 500 mm的箱体类零件,由于手臂可触及的范围有限,无法将支撑装置放置到指定位置,箱体类零件得不到很好支撑,导致零件加工后变形量较大。针对以上问题,研究了一种支撑装置,利用UG三维建模技术及虚拟样机技术对产品进行设计和虚拟装配,验证了支撑装置的合理性和可行性。支撑装置的使用使高度较小且深度较大的箱体类零件的制造周期缩短25%以上;同时,装置设置有压力传感器和显示系统,能够实时检测和显示支撑装置的支撑力,将支撑装置的调整时间减少30%以上,很好地解决了高度较小且深度较大的箱体类零件在机加工过程中支撑较难的问题,提高箱体类零件的加工精度和制造质量,为企业带来经济效益。
