Abstract

The present invention proposes a method and device for updating a map, wherein the method includes: obtaining comment information of points of interest to be processed in the map; performing word segmentation on the comment information, obtaining word sequences corresponding to the comment information, and vectors corresponding to each word in the word sequence ; Determine the vector corresponding to the comment information according to the vector corresponding to each word; input the vector corresponding to the comment information into the preset classification model to obtain the type of comment information; determine whether to delete the interest to be processed in the map according to the type of comment information Points, so that the points of interest in the map can be updated according to the comment information, without manual update, the map can be updated in time, the map update efficiency is improved, and the update cost is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for updating a map. Background technique [0002] At present, the way to update the points of interest in the map is that there is an entry for users to report errors on the map. When the user finds that a point of interest does not exist in the real world, an error will be reported through this entry, and the technician will report to the user. If the error is reported for verification, if it is true, the point of interest on the map will be processed offline, resulting in low map update efficiency and high update cost. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to propose a map update method for solving the problems of low map update efficiency and high update cost in the prior ...
