It uses ePSD and extensive lists of proper nouns to perform this analysis; it is an open-ended toolkit which will be added to intermittently. SumKit is documented here.
A Java-based program to view, navigate and edit syntax trees is in an advanced state of preparation. More discussion of this tool can be found here.
