Embodiment 1

[0059] figure 1 It is a flowchart of a method for updating a point of interest provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of updating the points of interest in the electronic map. The method can be executed by a device for updating a point of interest, and the device can be implemented by software and / or hardware. Typically, the device can be configured in a server corresponding to the electronic map. see figure 1 , the method for updating the point of interest provided in this embodiment includes:

[0060] S110. Obtain the point of interest to be updated.

[0061]Specifically, the method of obtaining the POI to be updated may be that the server obtains the POI in the electronic map according to the preset cycle and the set order as the POI to be updated; or, when receiving the update request sent by the terminal to the server, Obtain the points of interest in the electronic map according to the set order as the point...

Embodiment 2

[0089] figure 2 It is a flowchart of a method for updating a point of interest provided in Embodiment 2 of the present invention. This embodiment is proposed on the basis of the foregoing embodiments, and is an optional solution for classifying the POIs to be updated using a classification model. see figure 2 , the method for updating the point of interest provided in this embodiment includes:

[0090] S210. Construct a sample interest point data set.

[0091] Typically, constructing a sample interest point data set can include:

[0092] According to the preset construction rules, the sample interest point data corresponding to each category is filtered out from the pre-stored data.

[0093] Among them, the preset construction rules can be set according to specific categories, specifically, it can be judged whether the characteristics of the POIs of the corresponding category meet the set feature requirements, and if so, the POIs of the category are used as the sample PO...

Embodiment 3

[0110] image 3 It is a flowchart of a method for updating a point of interest provided in Embodiment 3 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see image 3 , the method for updating the point of interest provided in this embodiment includes:

[0111] S310. Construct a sample interest point data set.

[0112] Among them, the sample interest point data set includes two parts: training data and test data. The data composition mainly includes the following five sources: ultra-high-precision, high-precision, weak-variable, strong-variable and no-retrieval. data. In order to improve the accuracy of the model, the distribution of training samples is required to be as balanced as possible, so as to best describe the overall data distribution. The basic idea of ​​data set construction is: preliminary delineation of strategies and manual refinement screening, as follows:

[0113] Firstly, the existing p...

Abstract

The invention discloses a point of interest updating method and device, a server and a medium, and relates to the technical field of geographical information. The method comprises the following steps:acquiring points of interest to be updated; classifying the points of interest to be updated based on the characteristics of the points of interest to be updated; and updating the points of interestto be updated according to a classification result based on different preset updating standards corresponding to different types. Through adoption of the point of interest updating method and device,the server and the medium provided by the embodiment of the invention, updating is performed according to the characteristics of the points of interest, so that the point of interest updating accuracyis increased, and the problems that new points of interest cannot be updated online immediately, old and invalid points of interest cannot be cleared immediately and important points of interest arenot protected are solved.

Description

technical field [0001] Embodiments of the present invention relate to geographic information technical neighborhoods, and in particular to a method, device, server and medium for updating a point of interest. Background technique [0002] The graphics displayed in the electronic map are basically composed of points, lines and surfaces. As an important part of point data, interest points are an indispensable part of the electronic map; theoretically, any buildings, regions and points of specific significance that can be named can be Displayed as point of interest data, such as Tiananmen Square, a restaurant, community, parking lot, bus station, etc. [0003] The current method for updating the points of interest in the electronic map is: to update the points of interest in the electronic map by using a unified online and offline mechanism. Take the following offline as an example, the offline standard requires an accuracy rate of 90%, that is, if 100 sample POIs drawn from 1...
