Problems solved by technology

[0005] 1. The rule-based method, which is to find out the composition rules of personal names and place names, and match the sample data according to the composition rules, has the advantages of high efficiency and fast matching speed, but there are also obvious shortcomings: the coverage needs to be continuously improved Definition, for ambiguous words, the recognition rate of new words is low, and the labeling accuracy rate is low

Abstract

The invention belongs to the field of natural language processing in computational linguistics, and particularly relates to a method and a device for extracting Chinese names of people and places. The method comprises the following steps: S1, transforming text into an encoding format of UTF-8 (unicode transformation format-8); S2, presetting a text threshold L, judging whether text length T is larger than the threshold L, adopting an extension paragraphing method to paragraph the text and turning to step S3 after paragraphing if T is larger than L, and turning to the step S3 if T is smaller than or equal to L; S3, preprocessing the text to remove dirty data; S4, performing part-of-speech tagging on separate Chinese characters in the preprocessed text, and performing word separation and combination on the tagged separate characters; S5, marking phrases in the text, which are matched with target phrases, and calculating matching results. The method and the device can be widely applied to recognition of named entities in fields of search engines, machine translation, data mining and the like.

Description

technical field [0001] The invention belongs to the field of natural language processing in computer linguistics, in particular to a method and device for extracting Chinese names of people and places. Background technique [0002] With the changes of the times, information has shown explosive growth. In order to extract useful information from massive data, various fields are vigorously researching related technologies. A hot spot in the analysis, due to the complexity and ambiguity of Chinese itself, the research on the extraction of Chinese names and place names lags behind that of English. [0003] The reference patent document CN104182423A discloses a method for automatic recognition of Chinese personal names based on conditional random fields. By studying the characteristics of Chinese personal names and combining with a statistical probability model, an automatic recognition system for Chinese personal names is constructed. Reference patent document CN103870489A disc...
