Abstract

The invention provides an automatic correction method and an automatic correction device for a handwritten composition, wherein the method comprises the steps of: obtaining an image of the handwrittencomposition to be revised; using a connected domain analysis algorithm and a line detection algorithm to remove interference and background lines in the image of the handwritten composition; subjecting the processed image of the handwritten composition to line segmentation, word segmentation and recognition, and obtaining the corresponding text content; segmenting the sentences in the text content, performing the part of speech analysis on each sentence to acquire the word part of each word, performing shallow syntax analysis to obtain the phrases in the sentences and the types thereof, thereby selecting a rule strategy or depth model of a specific error type to detect specific grammatical errors; for each grammatical error detected, generating a correction suggestion by synthesizing therecognition result of the error recognition model and the correction suggestion model to obtain the results of correction of the entire composition, and constructing a convolutional neural network based on the content of the composition text and the results of the correction to achieve intelligent scoring of the composition text.

Description

technical field [0001] The invention relates to the technical field of homework correction, in particular to an automatic correction method and device for handwritten essays. Background technique [0002] The current composition correction method is mainly used to automatically correct the text content. After the text content is obtained, sentence segmentation and syntactic analysis are performed on the text content to obtain correction suggestions corresponding to each sentence in the text content, and then obtain the text. The correction result corresponding to the content. However, most of the current compositions are mainly handwritten compositions. Handwritten compositions have problems such as word sticking and line inclination. If the above composition correction method is applied to handwritten compositions, there will be problems of low correction accuracy and poor correction efficiency. Contents of the invention [0003] The present invention aims to solve one o...
