Method, device, equipment and computer storage medium for poi value evaluation

Abstract

The present invention provides a POI (point of interest) value evaluation method, device, device and computer storage medium, wherein the method includes: acquiring information of each first POI of known value and each second POI of unknown value within a certain area; POI information; constructing a value evaluation model; the value evaluation model is used to re-evaluate the value of the first POI by using the value of the surrounding POI of the first POI, and the surrounding POI includes other No. A POI and a second POI, and using the error between the value of the revalued first POI and the known value of the first POI to adjust the value of the second POI in the surrounding POIs; training the value evaluation model to minimize the error; Obtain the value of the second POI from the value evaluation model. Compared with the method of manually evaluating the value of POIs one by one, this method greatly reduces the requirement for manpower and improves the evaluation efficiency.

Description

【Technical field】 [0001] The present invention relates to the field of computer application technology, in particular to a POI value evaluation method, device, equipment and computer storage medium. 【Background technique】 [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] POI (Point of Interest) refers to a point of interest. It is a term in geographic information systems and generally refers to all geographical objects that can be abstracted into points. A POI can be a house, a shop, a mailbox, a bus stop, A school, a hospital, etc. The main purpose of POI is to describe the location of things or events, thereby enhancing the ability to describe and query the location of things or events. [0004] In Internet map applications, POI plays a very important role. Because the collection of POI i...

Problems solved by technology

The value evaluation of POI requires professional evaluators to give evaluation results with reference to various factors. On the one hand, the knowledge background of evaluators is required to be high. On the other hand, it is obvious to rely on evaluators to evaluate massive POIs in map applications one by one. Time-consuming, laborious, or even impossible to complete
