Embodiment 1

[0061] This embodiment provides a method for searching map POIs based on user data, such as figure 1 As shown, the method specifically includes the following steps:

[0062] S1. Obtain a target keyword input by a target user through a terminal.

[0063] In this embodiment, the target keyword input by the target user may be received through the search interface. The retrieval interface may be, for example, a retrieval interface corresponding to a retrieval box in a browser or a map APP (application program), or may be a retrieval interface provided by a system or an application program of an electronic device when some information is selected.

[0064] For example, the target keyword "People's Square" input by the target user is received through the search interface of a certain map APP. In this embodiment, keywords may be fields such as addresses, building names, and the like.

[0065] S2. Search for several target POIs corresponding to the target keyword.

[0066] In this...

Embodiment 2

[0101] This embodiment is a further improvement on Embodiment 1. In this embodiment, step S4 performs correlation scoring on each of the target POIs according to the personalized data of the target user as follows:

[0102] S41', according to the personalized data of the target user, acquire user characteristics and historical behavior characteristics of the target user.

[0103] In this embodiment, the user's personalized data may come from the Internet of Vehicles. User characteristics include, but are not limited to: gender, age, occupation category, industry, income level, and / or consumption level, etc. Historical behavior features include, but are not limited to: navigation destination, ignition address, ignition off address, passing address, browsed POI, and / or address when navigation is started, etc.

[0104] S42'. Based on the user characteristics and historical behavior characteristics of the target user, predict the probability that the target user prefers each of t...

Embodiment 3

[0111] This embodiment provides a map POI search system based on user data, such as figure 2 As shown, the system specifically includes: a keyword acquisition module 11 , a search module 12 , a sorting module 13 , a scoring module 14 , an adjustment module 15 , and a return module 16 .

[0112] The following describes each of the above modules in detail:

[0113] The keyword acquisition module 11 is used to acquire the target keywords input by the target user through the terminal.

[0114] In this embodiment, the target keyword input by the target user may be received through the search interface. The retrieval interface may be, for example, a retrieval interface corresponding to a retrieval box in a browser or a map APP (application program), or may be a retrieval interface provided by a system or an application program of an electronic device when some information is selected.

[0115] For example, the target keyword "People's Square" input by the target user is received ...

Abstract

The invention provides a map POI search method and system based on user data, equipment and a medium. The method comprises the steps: obtaining a target keyword input by a target user through a terminal; searching a plurality of target POIs corresponding to the target keyword; sorting the target POIs according to a preset rule; according to the personalized data of the target user, performing correlation scoring on each target POI; according to the correlation scoring result of each target POI, carrying out sequence adjustment on the sorted POIs; and returning the target POIs after sequence adjustment to the terminal, so that the terminal presents the target POIs to the target user in sequence. According to the method and system, the problem that the matching degree between recommendation of the POI and the retrieval intention of the target user is not high can be solved.

Description

technical field [0001] The invention relates to the field of POI search, in particular to a user data-based map POI search method, system, device and medium. Background technique [0002] The point of interest POI is also called Point of Information (information point). Generally, specific icons are used to represent POIs on electronic maps, for example, scenic spots, government agencies, companies, shopping malls, restaurants, etc. on electronic maps are all POIs. POI is the core data based on location services, and it can be used in a wide range of scenarios on electronic maps, such as selecting destinations before navigation, checking surrounding restaurants, etc. [0003] When retrieving POIs through keywords, recommendations are generally made based on objective importance such as the distance between POIs and the current location, the matching degree between POIs and keywords, the click-through rate of POIs, and the popularity of POIs. POI. However, because differen...
