Method and device of determining regional transaction, server and storage medium

Abstract

The invention provides a method and device of determining regional transaction, a server and a storage medium. The method and device of determining regional transaction take the transactional featureof a sample geographical region as a training sample, take the transaction labeling result of the sample geographical region as a sample label to train to obtain a transaction determination model, soas to obtain the transaction feature which can reflect the transaction condition following the time sequence for the geographical region to be tested, and input the transaction feature into the transaction determination model to obtain a determination result about whether the geographical region to be tested output from the model has transaction. The method and device of determining regional transaction make a determination of transaction from the perspective of the geographical region by means of the pre-trained transaction determination model, instead of targeting a single point of interestPOI, thus realizing determination of transaction of the entire geographical region to be tested without leakage of transaction of the single POI so as to enable determination of transaction to be morecomprehensive, so that updating of a map is more comprehensive and the up-to-date performance of the map can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method, device, server and storage medium for determining a regional transaction. Background technique [0002] Current status means that the geospatial information provided by the map should reflect the latest current situation as much as possible. To put it simply, current status refers to the extent to which the map reflects the status quo of geographic information. [0003] Under the new situation of rapid urban development, urban topography, landforms, and features change very frequently. In order to ensure the current situation of the map and reflect the actual changes of human and natural elements in a timely manner, the geographical elements that have changed in the geographical area must be revised or surveyed according to different situations and in accordance with unified technical requirements on the map that has been measured. Retest. [00...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, users generally report the change information of geographical elements, but this method is prone to under-reporting. For example, when a certain shopping mall is demolished as a whole, users may only report POIs (English: Point of Interest, Chinese : Points of interest) changes were reported, but changes of less popular POIs were not reported, resulting in incomplete map updates
