本发明公开了一种面向主题的城市轨道交通站点层次POI提取的方法。POI主要指一些如学校、银行等与日常生活息息相关的实体，可以很好的描述城市活动与城市土地的使用，为了了解站点周边的土地利用情况与客流情况，首先需要确定城市轨道交通站点覆盖区域内的POI集合；然后，根据指定的主题词和站点覆盖区域内的POI集合提取站点内相关主题的POI集合；最后，基于skyline思想根据站点内相关主题的POI集合提取站点的层次POI。 The invention discloses a theme-oriented urban rail transit station level POI (point of interest) extraction method. POI mainly refers to entities such as schools and banks closely related to daily life, urban activities and urban land use can be well described, and in order to know land utilization conditions and passenger flow conditions around stations, firstly, a POI set in an urban rail transit station coverage area needs to be determined; secondly, a POI set of related topics in the site is extracted according to the specified subject term and the POI set in the site coverage area; and finally, the hierarchical POIs of the site is extracted according to the POI set of the related topics in the site based on the skyline thought.
