Abstract: Several key questions for establishing the examination question system are studied. It can help embed the WORD into the WEB page, and thus use it to log and edit the questions. It supports the mixed arrangement of complex objects, and realizes the automatic layout of papers. In order to rid of the problem of questions accumulation and irrational distribution in the automatic generating paper, an improved algorithm of automatic generating paper is proposed. By means of dynamic monitoring of the range of the distributable values, the distribution of the sampled questions can be evaluated and the optimal subsets of the selected questions are determinated and then a random sampling can be made from the subsets of questions. Such a method can successfully rid itself of the problem of questions accumulation commonly found in automatic test paper generation. Examination papers generated by this algorithm are more scientific and rational.
