Problems solved by technology

[0003] However, no matter which classification method is used in the existing classification methods, if it is done manually, it will bring a huge workload, and different people will have more or less different subjectivity, especially according to the problem-solving ideas. When classifying, people have high requirements for mathematical foundation; and the existing classification methods can easily make the classification inaccurate, cause errors, and affect the subsequent series of operations

Embodiment 1

[0065] like figure 1 As shown, a method for automatic classification of question types based on problem-solving ideas for elementary mathematics includes the following steps:

[0066] a. Determine the topic to be classified and enter the topic;

[0067] b. Use the knowledge points used in the process of answering the standard answer of the input question as the problem-solving idea, and carry out the operation of extracting the problem-solving idea of ​​the question;

[0068] c. Judge the priority according to the importance of the textbook chapters, and roughly classify the topics into multiple fixed-number categories according to the priority;

[0069] d. Carry out fine classification for each major category of topics, and splicing them into multiple subcategories with an indefinite number according to the problem-solving ideas;

[0070] e. After fine classification, calibrate the topics in the sub-categories, output and save the classification results.

[0071] Elementar...

Embodiment 2

[0074] In this embodiment, on the basis of Embodiment 1, the step b includes the following steps:

[0075] b1. Determine whether the standard answer of the input question is marked with knowledge points, if yes, use the marked knowledge points as the problem-solving idea of ​​the question, and enter step b3; if not, enter step b2;

[0076] b2. Automatically mark the knowledge points on the standard answers of the input questions, and use the marked knowledge points as the problem-solving ideas for the questions;

[0077] b3. Extract multiple knowledge points in the topic to form a problem-solving idea.

[0078] This solution realizes the extraction of questions according to the problem-solving ideas, so that the final problem-solving ideas extracted for each question are a sequence composed of a set of knowledge points. If the standard answer of the question does not mark the knowledge points, it can be automatically marked according to the system. The knowledge points are us...

Embodiment 3

[0091] In this embodiment, on the basis of Embodiment 1, said step c includes the following steps:

[0092] c1. Determine the number of major categories to be divided;

[0093] c2. Prioritize the knowledge points according to the importance of the textbook chapters;

[0094] c3. According to the priority of the knowledge points, put the topics into the determined categories.

[0095] Preliminary rough classification of the extracted problem-solving ideas. Because the knowledge points involved in elementary mathematics can be divided into many small modules according to the arrangement of textbook chapters; The basics, so relatively speaking, the knowledge points in the following chapters are more important, and the priority of the knowledge points is higher. According to the priority of the modules and knowledge points, the topics to be classified are first divided into dozens of major categories, and usually the major categories The number is fixed; the rough classification...

Abstract

The invention discloses a question type automatic sorting method based on an elementary mathematics-oriented question-solving idea. After questions which need to be sorted are inputted, the knowledgepoint used in the answering process of the standard answer of the questions is taken as the question-solving idea, and the question-solving idea of the questions are extracted; the questions are roughly sorted into a plurality of main classes with determinate quantity according to priority; then the questions of each of the main classes are subtly sorted into a plurality of subclasses with indeterminate quantity; then the questions in the subclasses are calibrated, and the sorting result is outputted and saved. The invention further discloses a question type automatic sorting system based on an elementary mathematics-oriented question-solving idea. The system comprises a question inputting module, an idea extracting module, a rough sorting module, a subtle sorting module and a calibratingmodule. The method and system achieve more accurate pushing for users' exercises, improve user experience, and use the automatic sorting method to accelerate sorting process and to save labor and time.

Description

technical field [0001] The invention relates to the field of elementary mathematics calculation, in particular to an automatic classification method and system for elementary mathematics based on problem-solving ideas. Background technique [0002] There are many existing methods for classifying elementary mathematics questions, with different emphases and different categories. For example, according to different answering methods, it can be divided into filling in the blanks, selection, and problem solving; according to different knowledge categories, it can be divided into It is algebra, geometry, and function; and it is classified according to the problem-solving ideas, and the topics that are close to the problem-solving ideas are divided into one category, which is more convenient to realize the accurate push of user questions. [0003] However, no matter which classification method is used in the existing classification methods, if it is done manually, it will bring a ...
