Abstract

The invention provides a formula identification method and device. The method comprises the steps of obtaining to-be-processed data; extracting handwriting features of the to-be-processed data; generating a user behavior chain corresponding to the to-be-processed data according to the input sequence of strokes in the to-be-processed data and the handwriting features, wherein the user behavior chain is used for indicating a time sequence relationship between symbols in the to-be-processed data; and inputting the user behavior chain into a preset formula identification model, and outputting a formula identification result of the to-be-processed data. The method comprises the steps of generating a user behavior chain capable of indicating a time sequence relationship between symbols in to-be-processed data according to an input sequence and handwriting characteristics of strokes in the to-be-processed data; inputting the user behavior case into a preset formula recognition model, outputting a formula recognition result by the formula recognition model, indicating a time sequence relationship through a user behavior chain, and considering the time sequence of the formula in the recognition process, so as to simplify the recognition steps, shorten the recognition time and improve the recognition accuracy.

Description

technical field

[0001] The invention relates to the technical field of machine learning, in particular to a formula recognition method and device. Background technique

[0002] Technical problem: In related technologies, formulas can be identified by combining symbol recognition and structural analysis. This method requires symbol recognition for each character after the formula data is segmented, and then structural analysis. Each step in the process of formula recognition is independent, resulting in that the recognition process does not consider the timing of the formula, the recognition steps are complicated, the recognition time is long, and the accuracy rate is low. Contents of the invention

[0003] In view of this, the object of the present invention is to provide a formula recognition method and device, which considers the timing of formulas during the recognition process, so as to simplify the recognition steps, reduce the recognition time, and increase the recog...
