This presentation from CollegeAdvisor.com explores the challenges faced by international students in selecting graduate schools in the United States. With over 565,039 international students enrolled in 2006, the need for a robust, one-stop information source is essential. Our objective is to bridge this gap by offering in-depth university profiles, ranking data across various academic majors, and tailored recommendations based on user preferences. We utilize data mining techniques to provide personalized suggestions, diversified attributes for selection, and multimedia content to enhance the decision-making process.
