Abstract

The invention relates to the field of Internet teaching, and discloses a formula knowledge point recognition method and device, and the method comprises the steps: obtaining a character string set R corresponding to the information of all to-be-recognized formulas in a teaching resource, and a standard formula knowledge point set S matched with the content of the teaching resource; determining allpreliminarily corresponding standard formulas for each to-be-identified formula in the character string set R in the standard formula knowledge point set S according to the similarity of formula symbol feature information; and performing formula structure feature information matching on each to-be-identified formula and all preliminarily corresponding standard formulas to determine a standard formula uniquely corresponding to the to-be-identified formula.

Description

technical field [0001] This application relates to the field of Internet teaching technology, in particular to the field of teaching formula knowledge points involving science and engineering subjects. Background technique [0002] With the rapid development of computer technology, the application of computer-aided teaching in science and engineering subjects is becoming more and more extensive. At the same time, knowledge and information representations in science and engineering subjects include text, formulas, images and other forms, which bring challenges to the intelligent teaching of science and engineering subjects. [0003] At present, the digital processing of formulas in most teaching resources only solves the problem of formula recognition and presentation, and fails to effectively identify the knowledge attributes of formulas. This leads to the lack of comprehensive knowledge information of teaching resources, which cannot meet the application requirements such ...
