This will enable writing a plagiarism detector which will not be fooled by the simple strategy of replacing words with their synonyms. Given that synonyms have very similar embeddings, you can compute a distance between two phrases by computing the distance between their word embeddings. And that's just what comes to mind right now.
For sentiment detection, I could see a similar experiment to [1] working, but instead of discriminating between newsgroups, you classify sentiment.

I'm not sure how helpful that will be, as you may end up with a system that detects whenever a student expresses similar thoughts (and lets face it, the educational system is all about getting students to conform to conventional patterns of thinking) in their own words. And if the system doesn't detect re-expression of the same ideas, then a system that automatically rewrites essays in a slightly different style (essentially, an English-to-English neural machine translation) will defeat it. The endgame would be grading student essays on how well they express an entirely original idea, which is an unreasonable standard.
