Embodiment Construction

[0061] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0062] Since the present inventor has absorbed the essence of the double-array Trie for the invention and creation, before introducing the fuzzy query of the thesaurus of the present invention in detail, first introduce the double-array Trie.

[0063] If you want to query the double-array Trie, you first need to construct the double-array Trie, and determine the base value array and the corresponding check value array.

[0064] Assume that there are only words "Ah, Argentina, Ejiao, Arabia, Arabs, Egypt" in the thesaurus.

[0065] First, encode all 10 Chinese characters that appear in the lexicon: Ah-1, Ah-2, Ai-3, Gen-4, Jiao-5, La-6, and-7, Ting-8, Bo-9 , person-10. This encoding is not unique, it only needs to encode all the characters in the thesaurus one by one, which can be sequential encoding, or the corresponding encoding of each Chinese character that alre...

Abstract

The invention provides a lexicon fuzzy searching method, comprising the steps as follows: (1) an entry data structure is established: (1-1) all entries in the lexicon are sequentially memorized in the entry memory unit of the entry data structure; (1-2) a positive-direction entry searching structure of the entry date structure is established; all words of all entries are coded correspondingly; subsequently, double-array Trie is established to determine a basic value array and a corresponding calibration value array; subsequently, the memory address information of all words which begin with each affix in the entry memory unit is memorized; the affix is corresponding to the array unit of the basic value array and the calibration value array; (2) when a query sentence is received, codes of all words in the query sentence are gained and the double-array Trie is used to find the basic value array unit where the query sentence is; subsequently, the memory address information of all words which begin with the affix in the entry memory unit corresponding to the basic value array unit is found so as to find all corresponding words in the entry memory unit. The method has extremely fast query speed.

Description

technical field [0001] The invention relates to a thesaurus query technology, in particular to a thesaurus query method and a thesaurus query system. Background technique [0002] At present, information retrieval has developed to the stage of networking and intelligence.
