Abstract

The embodiment of the invention provides a method for determining error-correcting text and related equipment, which is used for improving the error-correcting speed of searching text. The method comprises the following steps of: obtaining a target search text input by a user; Segmentation of the target search text to obtain a segmentation set; Determining an initial error correction word corresponding to each participle in the participle set from a corpus; Calculating an error correction probability of an initial error correction word corresponding to each word in the word segmentation set; Determining an initial error correction word having an error correction probability greater than a first preset threshold value as a target error correction word for each word in the word segmentationset; A target error correction text of that target search text is determine from a target error correction word of each word in the word segmentation set according to a preset rule.

Description

technical field [0001] The invention relates to the search field, in particular to a method for determining error correction text and related equipment. Background technique [0002] On the live broadcast platform, search is a very important entry, and users can find the host they want to see through the search entry. However, for some reasons, users may make mistakes when entering the search text, such as spelling mistakes, reversed words, etc. If no error correction is done, it will be difficult to get the correct meaning from the search text, and it will not be possible to return what the user wants. search results. Therefore, it is necessary to adopt a certain method to correct the spelling of the search text. [0003] The usual search spelling error correction idea is to find the optimal hidden state (the most likely correct keyword) given the observation sequence (keywords input by the user), that is, to use the HMM model to complete the task. However, the search sp...
