String automatic correction method and system

Abstract

The invention discloses a method and system for automatically correcting character strings. The method for automatically correcting the character strings includes the following steps that a keyword database in which first kind words, second kind words, preset word groups and a word ranking sequence are recorded is generated; a word group ranking statistical table is generated according to the keyword database; the input character string is read; first kind words are selected from the input character string, and the character string is divided into keyword groups; effective word groups, words to be combined and ineffective words are selected from all the keyword groups; effective word groups are formed based on the words to be combined and according to the word group ranking statistical table; the output character string is generated; accuracy is calculated according to the word group ranking statistical table and is output. According to the method and system for automatically correcting the character strings, the concept partially based on word bank matching and partially based on a statistical probability is adopted, accuracy judgment can be conducted on input character string information, clerical errors generated in the user input process can be well recognized and automatically corrected, and therefore running efficiency of electronic commerce is improved.

Description

technical field [0001] The invention relates to a method and system for automatically correcting character strings. Background technique [0002] As e-commerce plays an increasingly important role in people's daily life, the authenticity and accuracy of user input information in e-commerce has also become the focus of many e-commerce companies. In e-commerce, it often involves filling in some information in a conventional format, such as delivery address and other information, and such information usually plays an important role in the interaction and communication between merchants and users. However, among the massive amount of information input by users, it is inevitable that some harassing information, namely false information, will appear. These two reasons make the authenticity and accuracy of some input information questionable, which hinders further communication between merchants and users or the conduct of transactions. [0003] In fact, small errors caused by cl...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome that in the prior art, it is impossible to automatically and efficiently make a relatively accurate judgment on the authenticity or accuracy of the character string information input by the user, and it is also difficult to better identify the character string information input by the user. In this case, the efficiency of e-commerce operations will be reduced and the cost of anti-fraud risk control is high. A method and system for automatic correction of strings are proposed.
