Table 3 Rules used for the post-expansion step. The rules switch certain part-of-speech tags to NEWGENE tags. We exclude 372/222 nouns from the expansion, and include only 778 particular adjectives in the expansion of noun phrases. NN*: nouns, proper nouns, plurals; JJ: adjective; CD: cardinal digit; DT: determiner; '/' refers to the token itself.
