Problems solved by technology

After permutation and combination in this way, a lot of homophone keyword groups will be generated, especially when the keywords entered by the user contain more Chinese characters, this phenomenon will be more obvious, and the efficiency will be greatly reduced. If these homophone keyword groups Screening and filtering, only retaining meaningful phrases, undoubtedly involves knowledge of grammar and lexical analysis, the threshold is high and the cost is high

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] The method for realizing Chinese homophone retrieval provided by the present invention utilizes the characteristic that the total number of Chinese characters is far lower than the total number of words composed of Chinese characters, and realizes homonym retrieval centering on Chinese characters. At the same time, the characteristics of the pronunciation of Chinese characters are used, but instead of using pinyin directly, each Chinese character corresponds to a homonym representative word. This method ensures that the original Chinese character information and the homophone representative word information have the same character and length. , which determines that the metadata information of the resource and its h...

Abstract

The invention discloses a method for Chinese homophone searching, which includes steps of: firstly, building mapping relationships between commonly used Chinese characters and homophones of the commonly used Chinese characters, and mapping original full-text contents in a search database according to the mapping relationships to obtain a database composed of a plurality of mapping records; secondly, mapping original search key words input by a user according to the mapping relationships to obtain homophonous strings of the original search key words; and thirdly, searching the homophonous strings in the database composed of a plurality of mapping records to obtain search results. By directly using the homophonous strings to search, circular exhaustion of various homophones of input words in traditional algorithm is avoided and searching efficiency is high. In addition, the method is independent of a homophone library, and no homophone library is needed, so that resources consumption and cost are lowered.

Description

technical field [0001] The invention relates to the technical field of Chinese character retrieval, in particular to a method for realizing Chinese homophone retrieval. Background technique [0002] Homophones are a characteristic of the Chinese language, and there are a large number of homophones in Chinese characters. It is very common for users to only know the pronunciation of a word but not its specific writing method when searching. Therefore, homonym retrieval, as an intelligent retrieval method, emerged as the times require. [0003] There are two traditional methods to realize the retrieval of Chinese homophones: one is to use the Chinese thesaurus, and the other is to use the pinyin of Chinese characters. [0004] The Chinese vocabulary (referring to the phrases composed of Chinese characters) is very large. If you use thesaurus to search for homophones, you need to build a huge homonym thesaurus, and when searching, you need to replace the keywords entered by the...
