NLP challenges: word ordering reverses meaning

Another good example:

When words are used in conjunction with each other, they express an idea that is bigger or more meaningful than each word in isolation. The two clauses I’m not happy I’m working and I’m happy I’m not working contain the sames words, in close proximity, but have quite different meanings.
