Equipment and method for error correction of query sequence based on degree of error correction association

Abstract

The invention provides equipment and a method for the error correction of query sequence based on the degree of error correction association, wherein the method comprises the steps of: acquiring a candidate error correction sequence corresponding to a query sequence input by a user through user equipment; selecting, from the candidate error correction sequence, the error correction sequence corresponding to the query sequence according to the degree of error correction association of the candidate error correction sequence; acquiring a query result corresponding to the error correction sequence according to the error correction sequence; and providing the query result for the user equipment. Compared with the prior art, the method completes reasonable selection for the corresponding error correction sequence through the degree of error correction association of the candidate error correction and provides the query result corresponding to the error correction sequence for user, which not only improves the error correction accuracy of search engine on the query sequence input by user, but also reinforces the interactivity between user and search engine so as to further improve the search experience of user.

Description

technical field [0001] The invention relates to the field of Internet search, in particular to a technology for error correction of network user input in Internet search. Background technique [0002] In the prior art, when a user enters a query sequence to search, sometimes an incorrect character string or phrase is generated due to a typo or improper word selection in the input method. If these incorrect character strings or phrases are directly used as query keywords At present, most search engines will take the initiative to give the query sequence after simple error correction, and the prompt form is such as, "Is what you want to search for ×××". At this time, the user can only passively accept the search results with "×××" as the query keyword. During this search process, the user can neither know the query sequence expected to be typed nor the query sequence after simple error correction. There is no way to choose other possible applicable candidate sequences other t...

Problems solved by technology

At this time, the user can only passively accept the search results with "×××" as the query keyword. During this search process, the user can neither know the query sequence expected to be typed nor the query sequence after simple error correction. There is no way to choose other possible applicable candidate sequences other than the simple error correction query sequence mentioned above. From the above, we can see that the error correction methods provided by current search engines are relatively simple, and it is very likely that Due to the low accuracy of error correction, it brings users a negative search experience and reduces users' dependence on search engines
