Embodiment Construction

[0039] The present invention locates the input Chinese characters from the Chinese dictionary by adopting the GB2312 or GBK encoding sorting method of the Chinese characters. Its core idea is: form an index table with the offset in the dictionary of the Chinese character in the Chinese dictionary relative to the starting position of the Chinese dictionary, and obtain the corresponding Chinese character from the index table according to the GB2312 / GBK encoding of the input Chinese character The offset in the dictionary, and finally locate the Chinese character directly according to the offset in the dictionary and the starting position of the Chinese dictionary.

[0040] The GBK encoding and GB2312 encoding of Chinese characters are both a Chinese encoding table formulated by the country, and a Chinese character is described by two bytes. GBK is an extension code of GB2312. This embodiment mainly uses GBK encoding as an example for description.

[0041] The basic GBK table fo...

Abstract

This invention discloses a method to rapidly find the Chinese character in the dictionary, which comprises the following steps: to form index form by initial and end position and the bias displacement of the dictionary; to get the relative dictionary bias displacement from index form according to the Chinese character code GB2312 / GBK; final to directly position the character according to the displacement and initial and end positions. This invention also discloses a Chinese dictionary-searching engine.

Description

technical field [0001] The invention relates to a Chinese dictionary search engine and a method for quickly locating words in the Chinese dictionary. Background technique [0002] For text search techniques, there are common techniques such as traversal and binary search. In the search technology of Chinese words, methods such as traversal are generally used, that is, a comparative search is performed one by one. [0003] This search method has strong randomness, and it takes a considerable amount of time to obtain results using a simple algorithm, while using a complex method requires a considerable amount of processing efficiency and memory space. Therefore, this method is not suitable for search applications with a medium-scale Chinese word data volume, such as Chinese dictionaries. In a word, when using the current search method to locate characters in the Chinese dictionary, the speed is relatively slow, resulting in low efficiency. Contents of the invention [000...
