Chinese address semantic parsing method facing address encode

Abstract

The invention discloses a Chinese address semantic analysis method for address coding. The method comprises the following: step one: according to sample data, establishing an address characteristic character library; a. establishing the sample data; b. screening characteristic characters; c. screening attaching characteristic characters; forming the characteristic character library by the screened characteristic characters and attaching characteristic characters; step two: according to the characteristic character library, converting the Chinese address into a numerical character string by the address expression rule; step three: establishing an address analysis rule library; and step four: performing the semantic analysis, comprising the address expression which is to convert the original address into the numerical expression and the address analysis, and divide the numerical expression address into address elements, and the address restoration which is to restore the analysis result of the numerical expression to a character string corresponding to the original address.

Description

technical field [0001] The present invention proposes a Chinese address semantic analysis method that does not rely on a gazetteer, and is suitable for geographic information systems (GIS) in the fields of real estate management, land management, urban planning, public security, postal services, taxation, telecommunications, public health, and number know-how address encoding. Background technique [0002] In daily production and life, addresses are one of the most commonly used reference systems for describing geographic locations using natural language. Address description is the most commonly used means to describe the spatial location in various business systems. Using address coding technology can convert a large amount of address positioning information that already exists in the management information system (MIS) into one that can be used in geographic information systems ( The geographic coordinate method of GIS) enables GIS to integrate, store, retrieve, operate, ...

AI Technical Summary

Problems solved by technology

However, due to the historical and cultural characteristics of the Chinese language itself, as well as the serious lack of address coding standards, there are serious irregularities in Chinese addresses, not only the regularity of address naming is poor, the format is complex, and there are multiple names in one place. , and adding, deleting, and modifying are relatively random

Obviously, the dictionary matching method cannot meet the needs of large-scale data processing in terms of scope of application, update maintenance, accuracy and response speed.
