Find all paragraphs of text that are related to a topic

Tuesday, July 1, 2014

Given a set of words ["college", "sports", "coding"], and a set of paragraphs of text (i.e. facebook posts), how can I see for each word the paragraphs that are related to that topic?


So for college, how can I find all the paragraphs of text that may be about the topic college?


I'm new to natural language processing, and not very advanced at regex. Clues about how to get started, what the right terms to google, etc are appreciated.
