Embodiment Construction

[0029] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0030] On the one hand, an embodiment of the present invention provides a retrieval system for continuous characters and fuzzy characters, such as figure 1 As shown, it is a schematic structural diagram of a retrieval system for continuous characters and fuzzy characters provided by the present invention, including:

[0031] The string pattern matching module uses the KMP string pattern matching algorithm to match short strings of consecutive characters in long strings; it should be noted that the string pattern matching module only matches continuous strings, that is, short strings are long A subset of character strings, such as the English name "apple", the user can input consecutive strings suc...

Abstract

The invention provides a retrieval system and method for continuous characters and fuzzy characters. The retrieval system comprises a continuous character string mode matching module, wherein a KMP character string mode matching algorithm is used for matching the continuous characters in a short string with a long string; when the character string mode matching module fails in matching, the retrieval system furthermore comprises a fuzzy character matching module used for taking out Unicodes one by one from the long string to be matched with the short string, and the characters corresponding to the Unicodes are Chinese characters or ASCII characters. Through the retrieval system and method, matching retrieval of the continuous characters and the fuzzy characters and polyphone retrieval of Chinese characters are achieved, wherein continuous character string mode matching is also suitable for retrieval of multi-linguistic characters, and fuzzy character matching is suitable for retrieval of Chinese characters or combinations of Chinese characters and ASCII characters; the Chinese character pinyin mapping table has good portability, can be used across platforms and is high in retrieval speed and efficiency.

Description

technical field [0001] The invention relates to the technical field of character retrieval, in particular to a retrieval system and method for continuous characters and fuzzy characters. Background technique [0002] In the car Bluetooth phonebook, the name in the user's address book may be Chinese characters, ASCII code characters, or both Chinese characters and ASCII code characters, or other texts, and the user can search according to the name of the address book by entering the corresponding characters The desired address book, such as: the name of the address book is "Zhang San", and the user wants to enter the pinyin abbreviation "zs" or the full name "zhangsan" or mix and match "zhangs", "zsan" to retrieve the communication of "Zhang San" Another example is that the name of the address book is "apple" in English, and the user wants to enter "apple", and "app" can retrieve the address book information of "apple"; another example is the user name "Zhang Love dog", the u...
