[0004] However, the names of repeated map POIs are not necessarily related, and the names of different map POIs are not necessarily unrelated. Therefore, the accuracy of removing duplicate map POIs based on name similarity is not high; and The method of removing duplicate map interest points by manual cleaning requires a lot of manpower input and is inefficient

The implementation of the present application provides a method and device for removing duplicate points of interest. The method includes: acquiring information of points of interest corresponding to each building and coordinates of feature points of each building, and each building is a building of a preset type ; According to the information of each point of interest and the coordinates of the feature points of each building, obtain the actual corresponding point of interest of each building; If the first building actually corresponds to M points of interest, then remove M in the M points of interest ‑1 POI; wherein, the first building is the building in each building, and M≥2. The repeated interest points determined by the implementation of the present application have relatively high accuracy, so that the accuracy of removing the repeated interest points is relatively high, and the removal efficiency is high.
Description
technical field [0001] The embodiments of the present application relate to computer technology, and in particular, to a method and apparatus for removing duplicate points of interest. Background technique [0002] The point of interest on the map is an abstraction of the elements in the real world, which blurs the shape characteristics of the elements, and only retains the specific information that can be described, such as the name and location coordinates of the elements, to indicate the elements in the real world. Due to the diversity of sources of map POIs, there is inevitably duplication, that is, two map POIs refer to the same element in the real world, which will affect the display effect of the map and the effect of users using the map to query. [0003] In order to solve the above problems, there are mainly the following methods for removing duplicate map points of interest: (1) The method based on name similarity, this scheme calculates the name similarity of mult...
