Problems solved by technology

Among them, the shortcomings of the UGC method are: firstly, it is necessary to mobilize the enthusiasm of users to upload through operational activities, and secondly, due to the randomness of the user level, the data quality is uncontrollable. The disadvantages of the PGC method are: firstly, the cost is high, and it needs to pay high labor costs, equipment costs, and transportation costs
At the same time, the coverage of the collection is low, and the timeliness is also often low due to the high cost. The defect of the web crawler method is that the coverage is low because POIs and aliases generally exist on the network.

Embodiment 1

[0025] Figure 1a It is a flowchart of a method for determining a POI alias in Embodiment 1 of the present invention, and this embodiment can be applied to the situation of determining a POI alias. The method can be executed by the POI alias determination device provided in the embodiment of the present invention, which can be implemented in software and / or hardware, and can generally be integrated in a computer device that provides a POI alias determination service, such as a smart phone, Tablet PC, vehicle terminal or server, etc. Such as Figure 1a As shown, the method of this embodiment specifically includes:

[0026] S110. Acquire a target POI to be processed, and generate a candidate alias list corresponding to the target POI according to the query behavior association log matching the target POI.

[0027] Wherein, the POI can refer to a certain point on the electronic map, which is used to indicate the function represented by the point, for example, the government depa...

Embodiment 2

[0046] Figure 2a It is a flowchart of a method for determining a POI alias in Embodiment 2 of the present invention. This embodiment is further embodied on the basis of the above-mentioned embodiment, and the alias candidates in the list of alias candidates are combined with the The association relationship between target POIs is to select at least one target alias corresponding to the target POI in the candidate alias list, which is embodied as: obtaining at least one target alias corresponding to each candidate alias in the candidate alias list An alias description feature; input at least one alias description feature of each of the candidate aliases into the pre-trained POI alias recognition model respectively, and obtain the output of the POI alias recognition model, and each of the candidate aliases Corresponding alias probabilities: according to the alias probabilities of each of the candidate aliases, at least one target alias is selected from the list of candidate ali...

Abstract

The embodiment of the invention discloses a POI alias determination method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-processed target POI, and generating an alternative alias list corresponding to the target POI according to a query behavior association log matched with the target POI; and screening out at least one target alias corresponding to the target POI from the alternative alias list according to an association relationship between each alternative alias in the alternative alias list and the target POI. According to the embodiment of the invention, the alias obtaining efficiency of the POI can be improved, the alias obtaining cost of the POI is reduced, and the coverage rate of the POI is improved.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular, to a method, device, computer equipment, and storage medium for determining POI aliases. Background technique [0002] With the development of science and technology and the continuous improvement of Internet technology, the services provided by mobile terminals are constantly upgraded. Currently, location-based services (Location Based Services, LBS) are a hot spot in current mobile terminal services. [0003] In LBS, Point of Interest (POI) has become a standard to measure the value of LBS. Among them, POI is an important part of the vitality of an area, which can specifically include retail stores, catering stores, entertainment venues or universities. In fact, different POIs have different names, and the names are used to identify POIs. Similarly, similar to a person having a first name as well as a nickname, POIs also have standard names and aliases....
