Error correction method and device

Abstract

The embodiment of the invention provides an error correction method and device and relates to the technical field of computers. The method comprises the steps that a target word to be subjected to error correction is determined; an error correction pair matched with the target word is looked up in a target error correction dictionary and used as a candidate error correction pair, wherein the target error correction dictionary is a pre-established error correction dictionary, each error correction pair stored in the target error correction dictionary is obtained after a sample word is subjectedto error correction through an error correction model, and the error correction model is obtained after a first preset model is trained by using the error correction pair in a known error correctiondictionary; according to the found candidate error correction pair, an error correction result of the target word is obtained. Compared with the prior art, the error correction method has advantages that when the target word to be subjected to error correction is subjected to error correction, an error correction word of the target word can be found in the target error correction dictionary with high probability, and therefore the failure probability of error correction on the target word is lowered.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to an error correction method and device. Background technique [0002] With the rapid development of Internet technology, users can obtain more and more information from the Internet. When a user searches for desired information, he generally enters a search term in the client he uses, and the client obtains information that matches the search term entered by the user, and displays the obtained information to the user. [0003] However, when the user enters the search term, there may be input errors. In order to ensure that the user is provided with the information that the user wants, after obtaining the search term entered by the user, the above-mentioned search term is generally corrected. [0004] In the prior art, when performing error correction processing on a search term entered by a user, the search term entered by the user is generally matched with an error correction p...

Problems solved by technology

[0005] However, the inventor found in the process of implementing the present invention that at least the following problems exist in the prior art: because the error correction pairs contained in the known error correction dictionary are not comprehensive enough, when performing error correction processing on the search words input by the user , it is difficult to find an error correction pair that matches the above search term from the known error correction dictionary, resulting in a high probability of failure when error correction is performed on the search term
