Method and device for correcting error in text

A device for correcting an error in a text, comprising:

• one or more processors;
• and
• a storage device configured to store one or more programs, that, when executed by the one or more processors, cause the one or more processors to:
• preprocess the text to obtain at least one segment of the text;
• generate a plurality of candidate segments for the segment;
• score the plurality of candidate segments with a tree model, to obtain respective first scoring results of the plurality of candidate segments;
• score the plurality of candidate segments with a deep neural network model, to obtain respective second scoring results of the plurality of candidate segments;
• for each candidate segment, calculate a scoring of the candidate segment based on the first scoring result and the second scoring result of the candidate segment;
• rank the plurality of candidate segments according to the scorings of the candidate segments, to obtain a ranking result;
• and
• correct the error in the text according to the ranking result.
