Abstract

The invention discloses an address identification method and device and a storage medium. The method comprises the steps of obtaining an address fragment sequence obtained after segmentation of a to-be-identified address text; obtaining a splicing feature vector matched with the address fragment sequence; inputting the splicing feature vector into an address identification network model, and obtaining an output result output by the address identification network model, wherein the address identification network model is obtained by deeply learning a plurality of training samples; according tothe output result, identifying an address role label sequence matched with the address fragment sequence, wherein the address role label sequence includes address role labels matched with all addressfragments included in the address fragment sequence respectively. The technical problem that in the related technologies, the address identification result is low in accuracy is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to an address identification method and device and a storage medium. Background technique [0002] In geographic information systems, it is often necessary to identify, analyze and process various address texts manually input by users, so as to assist users in address positioning or map navigation. Wherein, the above-mentioned recognition and analysis processing of the address text includes: address word segmentation processing and address recognition processing. That is to say, usually after obtaining the long address text input by the user, it needs to be segmented first to obtain multiple address segments, and then match the corresponding address roles for the address segments, where the address role is used to identify The address level at which each address segment resides. Finally, the address matching the address role is applied to the process of address positioning or map ...
