Data error correction method and device and server

Abstract

The invention disclose a data error correction method and apparatus, and a server. The method comprises steps of obtaining a search term inputted by a user; matching the search term with a pre-createddictionary tree to obtain a matching result, the dictionary tree comprising a plurality of nodes, and each node in the plurality of nodes being used for representing a word segmentation segment of areference word in a reference word list; if the matching result indicates that the search term is not matched with the dictionary tree, obtaining a feature vector of the search term, and determining atarget reference term from a plurality of reference terms included in the reference term list according to the feature vector of the search term; and taking content matched with the target referenceword in a database as a search result of the search word. According to the method, automatic error correction can be accurately carried out on the search term, and data query efficiency and accuracy are improved.
