r/MachineLearning - Sourcing data for a job recommendation system [research]

I'm an undergraduate data scientist, about to start work on my dissertation project. I thought I'd create a system that, given someone's career history and education, predicts what job they're likely to get, and at what company. Essentially this is to help focus the efforts of job seekers, and help them get to where they belong. Originally I planned to do this by scraping data from LinkedIn profiles. From the LinkedIn profile, you can obtain information about someone's current job and employer, as well as their career history and education. Therefore you can see what education and career history (the input) resulted in their current job (the output - the thing I'm trying to predict).
