- Extracted from the BROWN file all grammar rules embedded in parse trees. (Did not consider punctuation as a nonterminal and eliminated numbers attached to non-terminals such as '-1', '-2', etc.)
- Reported the following:
- number of distinct rules found.
- the 10 most frequent rules regardless of the non-terminal on the left-hand side
- the non-terminal with the most alternate rules (i.e. the non-terminal that can have most diverse structures).
- Estimated the above grammar size if lexicalized (i.e. to add head words to some of the rules).
