With the transformation of higher education from elite education to mass education in China, the number of college graduates has increased year by year, and the employment situation of college graduates has become increasingly severe. How to predict the employment of graduates effectively are not only a concern of college students, but also employers, employment guidance departments and the society. The traditional employment forecasting method usually lacks the deep use of intrinsic data and external data of college students. This paper proposes a prototype, information to Intelligence (itoI), which collects various kinds of information to predict the employment of graduates. The prototype system makes full use of intrinsic data and external data of college student to make horizontal comparisons and vertical comparisons. As a result, it provides college students with career prediction and suggestions. Through the random survey on college student and analysis on historical employment data of Shandong Normal University, the experimental results show that the method has high prediction accuracy, and it can effectively provide students with reference on future employment. It is invaluable and useful for guiding employment.
