I've experimented with this for a while, the goal being easier comprehension of new text. I found highlighting parts of speech and syntactic groups didn't work for me. The only thing that did work was highlighting keywords (that are specific to the text) and maybe named entities that refer to the same thing. Interestingly, there is some research indicating highlighting keywords may help people with dyslexia. I've written a chrome extension for highlighting keywords, too bad I don't currently have time to give it the love it deserves: https://chrome.google.com/webstore/detail/highlit/cooahmcpmajfpnanjkdfiejkffphknnm https://chrome.google.com/webstore/detail/highlit/cooahmcpma...
