摘要：

针对智慧商圈建设过程中各类数据需求,设计一个多源数据采集与综合评价系统。利用Pyspider框架采集数据,基于二分思想和多边形规则对采集的数据进行商圈边界探测、商圈内点判定,通过构建一套兴趣点与商圈的映射规则,解决不同数据源对商圈定义不同的问题。利用融合后的数据,从60多个维度进行商圈结构分析和对标分析。实验结果表明,该系统能为各类分析模型提供数据支持,从而为各类商业行为提供决策支撑。

Abstract:

Focusing on the data requirement of intelligent business district’s construction,this paper designs a multi-source data acquisition and comprehensive evaluation system.The system uses the Pyspider framework to collect data.Based on the idea of dichotomy and the rules of polygon,the business district boundary detection and the inner district point determination are conducted and used to set up the mapping rule between Point of Interest(POI) and business district.In this way,the different definition of business district from different data sources can be solved.Furthermore,60 features are extracted from the integrated data to analyze the structure and comparison of business districts.Experimental results show the system can provide data support for various types of analysis models which can provide some decision support for business behaviors.

Key words: intelligent business district, multi-source data, data integration, boundary detection, evaluation model
