Abstract
The invention discloses a method for randomly generating examination paper. The method includes steps of S1, acquiring examination question information inputted by users; S2, judging whether examination questions in examination question banks are matched with the examination question information or not, executing a step S4 if the examination questions are matched with the examination question information, or executing a step S3 if the examination questions are not matched with the examination question information; S3, modifying the examination question information and returning to the step S2; S4, randomly extracting the examination questions from the examination question banks according to the examination question information and generating the examination paper according to the extracted examination questions. The method and the device have the advantages that the examination questions in the examination question banks are compared to the examination question information inputted by the users, whether the paper can be successfully constructed or not can be quickly judged in a local similar backtracking mode, accordingly, the quality of random algorithms can be guaranteed, large quantities of useless operation and infinite loops can be prevented before paper constructing failures, the paper constructing time can be saved, the paper constructing efficiency and the quality of the examination paper can be improved, and the paper constructing success rate can be increased.
Description
Technical field
The present invention relates to field of computer technology, be specifically related to a kind of method and apparatus of stochastic generation paper.
Background technology
Examination, as a kind of means detecting knowledge dissemination effect, exists for a long time always.Tradition examination needs experience to set a question, prints examination question, tissue examination, correct an examination paper, many processes such as interpretation of result and explanation, the front and back duration is longer, spends a large amount of manpower and materials.Along with the development of multimedia technology and the network communications technology, the Internet is applied to work and the life of people more and more, for traditional test way brings new thinking.The appearance of On-line Examining system; provide a kind of brand-new curriculum test means; break traditional test way restriction over time and space; the diversity of its content; the demand of different levels can be met, substantially increase work efficiency, save cost; and decrease paper waste, be conducive to environmental protection.
In the generation paper stage of online testing, usually need to choose exercise question automatic volume group from existing exam pool, the algorithm used in automatic volume group comprises: random approach, backtracking method and genetic algorithm.Compared with random approach, backtracking method and genetic algorithm realize more complicated, and the Examination Papers ' Quality of generation is lower, and when volume is less time, use genetic algorithm easily to occur that twice, front and back paper content repeats higher situation; And when using existing random approach, it is lower that group is rolled into power ratio, likely can be absorbed in endless loop or occur the situation that paper is heavily inscribed, affect group volume quality.
Summary of the invention
The invention provides a kind of method of stochastic generation paper, be rolled into the lower defect of power ratio to solve group in prior art.
The invention provides a kind of method of stochastic generation paper, comprise the following steps:
