| The college entrance examination is undoubtedly one of the most concerned events every year,affecting the hearts of hundreds of millions of families.Obviously,college entrance examination has great significance for all students and families,it has been valued by school,family and society,and also has been regarded as the turning point of life.Enter the ideal university is not just get a good marks,voluntary filing is also a key factor in deciding whether to enter an ideal institution or an ideal profession.However,volunteer fill has not get enough attention in terms of the relative importance of the college entrance examination.Students and parents spend a lot of time and money into get good grades,and overlook the importance of college choice decisions in college entrance examination.Moreover,there is not enough information to guide the college choice decisions of students,due to resource access and other aspects of the limitations.Student get a good score is a prerequisite,a good choose also very important.Therefore,the position of college choice decisions can be just after good grades for all students,it can be regarded as the "second college entrance examination".It would become the great regret in life,if students can't enter to an ideal university due to failed of college choice decision.In the gradient of volunteer,every year many candidates failed to enter the ideal institutions because of the wrong volunteer fill.With the implementation of parallel volunteer,it makes candidates have more opportunities to choose,but risk still exists,due to failed college choice decisions.There are some teachers,candidates and parents can't analysis of the previous data correctly,which lead to the failed of college choice decision,resulting the high scores candidates can't enter their favorite college or even out of the list.College entrance examination volunteer is an indispensable part of the the college entranceexamination,and many people called "the second college entrance examination".However,every year a large number of candidates can't enter their ideal institutions and professional,and even come down,because they can't effectively analyze the data,just use the surface information.In view of the problems in the application,the article has carried on the scientific analysis and processing to help the students to choose the institution and the profession professionally,reduces the possibility that the high score student enters the unsatisfactory college profession or even fails.Due to the inconsistency of college entrance examination information of different years and the volatility of admission,it is impossible for candidates to choose the right professional and institution according to the existing data.This paper presents a volunteer decision model based on data analysis.Firstly,the data is normalized by the fractional-rank-fraction conversion.On this basis,the appropriate data analysis coefficients are selected according to the changes of the enrollment numbers in different years,so that the calendar year scores are more reference value.Then,according to the type of college fluctuation,the smoothing coefficient is determined,and the second index exponential prediction is made to predict the trend of the admission score.The key points in the model are established,and the admission probability model is established.According to the proposed model to calculate the probability of admission to institutions,institutions will be stratified by probability clustering for the candidates to determine the scope of institutions;Finally,through the candidates to select the characteristics of the preferences and ratings,to calculate the similarity between the ideal institutions,and as an evaluation,as one of the evaluation indicators,to complete the institutions recommended.The experimental results show that the decision-making model can provide the decision-making support for the candidates according to the factors such as the scores,the self-condition and the preference of the candidates. |
