Error correction method and device

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 t
