Power grid power failure address matching method based on word bank two-way maximum matching method

Abstract

The invention provides a power grid power failure address matching method based on a word bank two-way maximum matching method, which comprises the following steps of: 1, constructing a power failureaddress element library which comprises an address element word bank, a stop word bank and a synonym bank; 2, preprocessing a to-be-matched address text by utilizing the stop word bank and the synonymbank; 3, performing word segmentation on the to-be-matched address text by utilizing a bidirectional maximum matching word segmentation method, and segmenting an address element sequence of a to-be-matched system; and 4, comparing the address element sequences of the to-be-matched system according to an address element matching rule, judging whether the address element sequences are matched or not, and listing difference items if the address element sequences are not matched. By dynamically maintaining the power grid power failure address element library and performing abbreviation filling processing on the address elements, the address text word segmentation recognition rate can be improved, address element matching of a single address item can be processed, the address element matchingproblem of multiple address items can also be processed, and the address element matching accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the field of power grid distribution data management, in particular to a power grid outage address matching method based on a lexicon bidirectional maximum matching method. Background technique [0002] In recent years, with the continuous improvement of high-quality services, the purpose of People's Electric Industry for the people has been deeply rooted in the hearts of the people, and the lean management of power outage plans is imperative. At the same time, with the rapid development of smart grid informatization, a large number of information management systems serving various professions have been gradually built and applied, and a large amount of data with rich value has been generated. However, because these information management systems are affected by the "silo-style" management mode of different departments, it is easy to form information islands, resulting in data quality problems such as multiple data sources, inc...

Problems solved by technology

Literature [5] proposes a place name and address matching technology based on a compound dictionary. Although it solves the problem of unregistered word recognition to a certain extent, it is difficult to establish a dictionary

Literature [6] proposes a Chinese address word segmentation algorithm supported by a Chinese address knowledge base, but the segmentation of address elements is not clear enough
