Embodiment Construction

[0072] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0073] figure 1 Shown is the topological structure diagram of the knowledge system in the computer field, including: courses (Course), knowledge modules (Module), knowledge units (Unit) and knowledge points (Point), which satisfy the relationship described in formula (1). In order to realize the maximization and equalization of the knowledge point coverage of multiple sets of test papers, each question in the design question bank of the present invention is associated with a specific knowledge point. According to the formula (1), each question also belongs to a specific knowledge point at the same time. knowledge units, knowledge modules and a course. Therefore, the question attributes in the design question bank include:

[0074]

[0075] refer to figure 2 , the present invention takes the set test paper conditions as input, and the test test process i...

Abstract

A B / S mode automatic examination paper method based on the knowledge system in the computer field, including the following steps: 1: According to the examination paper conditions, judge whether the current question bank meets the examination paper requirements, otherwise reset the examination paper parameters; On the basis of the domain knowledge system, a random extraction algorithm is adopted, according to the sequence of knowledge modules and knowledge units within the module, following the priority principle of knowledge points that have not been extracted, and sequentially extracting questions that have not been extracted before in the specified question types for each test paper , until all the questions required by the conditions have been extracted; three: after the topic extraction is completed, calculate the average difficulty value of each type of question in each test paper, otherwise the difficulty value is adjusted by using a cyclic replacement algorithm until the requirements are met; using the present invention, it can be solved When it is necessary to organize multiple sets of test papers at the same time, it is required to ensure that there are no repetitions of test questions in multiple test papers, the distribution of knowledge points in each test paper is balanced and maximized, the difficulty of each test paper is the same, and the scope of test papers can be flexibly set.

Description

technical field [0001] The present invention relates to a method for automatically forming papers when multiple test papers with completely different topics need to be generated simultaneously in online examinations of university computer courses, and in particular to a method for automatically forming papers in B / S mode based on a knowledge system in the computer field, specifically A B / S mode automatic examination paper method based on the knowledge system in the computer field, which maximizes the coverage of knowledge points and balances the difficulty. technical background [0002] With the development of Internet technology and large-scale online education technology, online examination mode has been more and more widely used. Traditionally, the test papers for online exams are manually written and entered by teachers. Not only is the workload heavy, but it is also difficult to ensure that the knowledge points are covered evenly and the difficulty is consistent. There...
