Thought I'd drop a link in here to an article written a while back while I was learning GraphAware's NLP plugin. I thought it was pretty amazing -- not my work at all, make sure to give your kudos to @Christophe_Willemsen when you check this out (and GraphAware's other plugins & framework)
From time to time, we do a lot of work with social media data at Neo4j as part of our data journalism program, and it's really powerful to be able to have these tools lying around to pull text out of our graphs and enrich social media posts with concepts, people, places, and sentiments being mentioned. Definitely would recommend checking it out.
