There is no universally defined set of keywords. You will need to define more clearly what needs to be extracted from the document, and you will need to describe what "document" means to you.

Have you done OCR yet, so that you have a list of strings in a cell array? If so, I think you could construct a histogram of word frequency using uinque() and ismember(). I don't have a demo, try it yourself.

You might also like allwords to split a big long string of many, many words up into a cell array of individual words, which you can then use with unique() and ismember().
