Description

technical field [0001] The invention relates to computer retrieval technology, in particular to a Chinese text retrieval method and a Chinese text retrieval device. Background technique [0002] With the rapid development of communication technology, all kinds of information have shown explosive growth. In today's information age, how to quickly and effectively retrieve the required information has become a hot topic of concern to users and various information operators. Serving one of the most fundamental goals. [0003] Information search (or information retrieval) refers to the keywords that are queried and extracted from the stored information database by string retrieval, regular expression retrieval or other methods after keyword extraction based on the search string entered by the user.

Problems solved by technology

In this way, if the search string entered by the user is "abridged", only search results related to "abridged" can be obtained, but not related to "abridged", "abridged", "abridged", "abridged", etc. Relevant search results make the search results relatively single and cannot cover the associated search information base, making the search efficiency low; if the user needs to obtain a wider range of search results, he needs to input "Abridged", "Abridged", "Deleted" in sequence "section", "deletion" and other string search words, or input "[deletion][section]" through regular expressions, both methods require the user to know the corresponding variant characters, traditional characters, Tonghua characters, etc., have high requirements for users, so, in actual retrieval applications, lack of enforceability
