Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0065] The existing Chinese address completion method is to query the entry information matching the input address in the database, which is very dependent on the performance of the database and the optimization of query conditions. When the database is too large, the query rate will decrease. Another solution is to use the inverted index method to optimize the query. This method needs to pre-design the database and create a good index, and the workload is heavy.

Abstract

The embodiment of the invention provides a Chinese address completion method and device, equipment and a storage medium, and aims to realize quick search and completion of a Chinese address without influencing performance of a system when a database is increased. The method comprises the following steps: storing a complete address in an address library according to a Trie tree structure; marking the address level of each path on the last node of the path in the Trie tree; searching an input address keyword in the Trie tree to obtain the address keyword marked with the address level; and analyzing the annotation information in the address keyword to obtain the complete address corresponding to the address keyword.

Description

technical field [0001] The embodiments of the present application relate to the technical field of information processing, and in particular, relate to a method, device, device and storage medium for Chinese address completion. Background technique [0002] Chinese address completion is a technology closely related to people's daily life. Its purpose is to complete the incomplete address entered by people into a complete address. It has important uses in various scenarios and applications, such as online shopping, when handling documents Fill in the address. One of the existing address completion methods is to store a large amount of address information in the database, and then query according to a specific field. Another solution is to optimize the query by using an inverted index. [0003] The disadvantage of the existing technology is that when the database is too large, the efficiency of address query will be reduced, and the query time will increase nearly linearly. T...
