This interactive chart lets you explore the words used to describe male and female teachers in about 14 million reviews from RateMyProfessor.com.
Not all words have gender splits, but a surprising number do. Even things like pronouns are used quite differently by gender.
Pick a word (or two-word phrase) from the box above to see how it is split across gender and discipline: the x-axis gives how many times your term is used per million words of text (normalized against gender and field). Or limit to just negative or positive reviews (based on the numeric ratings on the site). For some more background, see here.
