Abstract

The invention provides a method for digging a non-recalled type error correction word of a searching engine. The method comprises the following steps: the searching engine obtains a conversation log of a user, wherein the conversation log at least comprises a first conversation and a second conversation, and the first conversation and the second conversation respectively comprise a first searching word and a second searching word; the searching engine obtains related relation information between the first searching word and the second searching word; the searching engine judges whether the first searching word is the non-recalled type error correction word or not according to the related relation information. The invention further provides a device for digging the non-recalled type error correction word of the searching engine. According to the method and the device, modeling analysis on a user searching word sequence and a searching result is carried out so that the non-recalled type error correction word can be automatically found, and the recalling efficiency is considerably higher than that of manual searching; the manpower cost for finding out the non-recalled type error correction word is greatly reduced.
