title: Creating parse trees in NLTK using tagged sentence
body: <p>Using the methods defined in <a href="http://www.nltk.org/book/ch08" rel="nofollow noreferrer">the NLTK book</a>, I want to create a parse tree of a sentence that has already been POS tagged. From what I understand from the chapter linked above, any words you want to be able to recognize need to be in the grammar. This seems ridiculous, seeing as there's a built in POS tagger that would make hand-writing the parts of speech for each word completely redundant. Am I missing some functionality of the parsing methods that allows for this?</p>
