You might have a look at "Data Structures and Efficient Algorithms in
Mathematica" at

http://library.wolfram.com/infocenter/Conferences/321/
Or grab notebook directly at
http://library.wolfram.com/conferences/devconf99/lichtblau/

The last section, "Tree application: A rudimentary parser", has a random
sentence generator (uses a simple LL grammar, for those who care about
such things). You can swipe the grammar and word lists, and alter to
taste.
