Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0025] Such as figure 1 As shown, a positioning method includes steps:

[0026] S100: Analyzing the input full address to obtain multiple characters.

[0027] Analyze the input full address to obtain multiple characters. The composition of the full address can include Chinese characters, English, numbers, and special symbols. The specific types of inclusion need to be determined according to the actual situation. The type of characters obtained after parsing can also include multiple types.

[0028] S200: Identify the types of the multiple characters, and merge characters of the same type into the same block, wh...

Abstract

The invention provides a positioning method and system. The positioning method includes the steps that full addresses are traversed to obtain a plurality of characters through analysis, the characters of the same types are combined into the same blocks, word segmentation is performed on the blocks one by one through a forward maximum word segmentation algorithm, segmented words are grouped according to administrative regions, integrals of groups are calculated, and the group with the largest integral is selected and analyzed to obtain the addresses for positioning. The whole process is rigorous in processing, positioning is achieved through the characters, the blocks, the segmented words and the groups, the addresses are truly and accurately obtained by adopting the forward maximum word segmentation algorithm and taking weight coefficients of the different administrative regions into consideration, a user does not need to take part in, and positioning accuracy and the positioning success rate are high.

Description

technical field [0001] The invention relates to the technical field of location services, in particular to a positioning method and system. Background technique [0002] At present, the common word segmentation algorithm in the market is based on the application of address location services. The main implementation is to perform word segmentation through fuzzy matching between keywords and dictionaries, and feed back all the word segmentation results to the front end for users to judge. The above method requires the participation of front end users or It can only be applied to scenarios that do not require high positioning accuracy. [0003] With the continuous improvement of people's demand and requirements for positioning services, the requirements for positioning accuracy and positioning success rate are also increasing. The above method can only achieve simple positioning, and also requires the participation of front-end users, which obviously cannot meet people's needs....
