Embodiment Construction
[0049]In order to solve the problem of low accuracy of the address matching method, this application provides a new address matching method, which divides the address elements with priority from the text address, and then matches them step by step according to the priority of the address element type. Thereby, the accuracy rate of address matching is improved. The address matching method can be applied in many different application scenarios, for example, in a police geographic information system or a logistics information system.
[0050] See figure 1 , figure 1 It is a flow chart of one implementation of the address matching method of this application. The matching method includes the following steps from S100 to S400.
[0051] S100: Segment the text address to be matched to obtain at least one address element, where each address element has a corresponding address element type.
[0052] In order to facilitate administrative management, the state divides the territory in...

The embodiment of the invention discloses an address matching method and device, and the method comprises the steps: segmenting a to-be-matched text address, obtaining at least one address element, and enabling each address element to have a corresponding address element type; determining a first query condition according to a preset priority of the address element type; searching a standard address library to obtain a first query result, wherein the first query result comprises all standard addresses meeting the first query condition; and if the number of the standard addresses in the first query result is within a preset threshold range, a target address is screened out from the first query result, and the lower limit value of the threshold range is greater than 0. By adopting the address matching method in the technical scheme, the step-by-step query is performed according to the priority of the address element type, and the target address is screened from the reasonable query result, so that the target address can be accurately matched, and the address matching accuracy is improved.
Description
technical field [0001] The invention relates to the field of natural language processing, in particular to an address matching method and device. Background technique [0002] Geographical information is currently the most commonly used social public information resource, which is closely related to the daily life of the public. At the same time, it is also the basic resource for basic administrative management of the government. Text address refers to the geographic location described in words, such as "Beiyuan Road, Chaoyang District, Beijing". Address matching is the process of mapping textual addresses to geographic locations in space, or geographic coordinates. For example, the user inputs a text address into the terminal device, and the terminal device returns the latitude and longitude coordinates of the geographic location described by the text address, so as to locate the address on the map. [0003] When performing the task of address matching, generally, it is f...
