Do you have a predefined list of what you deem to be a keyword and or keyphrase?

Do you think the computer will magically *know* what those are supposed to be?

(How do you think google and them figure out what the keywords and keyphrases are? They are told this by what their machines see on the web, if two pages link to another with the anchor text 'bogus meatball', then that is now a keyphrase to them of some value. )

Are you going to be using a dictionary list, a list that you have at work... etc etc etc..
