[Abstract]:The scale of higher education in China is expanding, especially since the elite education turns to "popular" education, the number of university graduates increases year by year, and the problems of employment become more and more prominent. College students are a group of numerous hopes and eyes of the country, society and family. How to help them to find a job suitable for their specialty and specialty after graduation is an important subject that every university generally faces. The establishment of employment guidance course can guide and help college students to fully understand their own characteristics, understand social needs, and finally succeed in employment. It is also an effective and necessary way to solve the problem of employment of college students at this stage and to improve the employment rate of colleges and universities. In the environment where Web technology is widely used, the design and development of "Employment guidance" network course can promote the development of employment guidance work more effectively, and ensure the possibility for students to study courses at any time and anywhere. In this paper, the idea of data mining is introduced. Database technology is becoming more and more mature, and the information stored in database is growing rapidly. According to the survey, more than 80% of the data stored in the information management systems of colleges and universities only provide simple query function, and the potential relationships hidden in these data are almost not found and utilized. The author takes the student achievement information in the educational administration management system of S University, the student employment information in the employment database as the object, combines the student basic information and the performance during the school period, The feature selection algorithm based on support vector machine (Support Vector Machine,SVM) in data mining technology is used to find out the internal relationship between the information in these different databases. On this basis, the application of the experimental results in the construction of the online course "Employment guidance" is analyzed, which provides a theoretical basis for the construction of the learning platform of the course. The paper is divided into five chapters. The first part introduces the background, significance and purpose of the research, as well as the research ideas and methods, so that readers have a general understanding of this paper; The second part describes the theoretical basis of this research topic, and introduces the current research situation, the third part of the data mining technology is summarized, focusing on the introduction of the relevant concepts of SVM, The fourth part is the key part of this paper, after collecting and preprocessing the original data, using the feature selection method based on SVM to analyze the data, finally get the results of the experiment. To explore its practical guiding significance for the construction of the network course of Employment guidance. The last part is the conclusion of the paper.
