Table 2 Rule set for shallow parsing. The rules are used to identify general verbal and prepositional relations between noun phrases in text. N is a noun, Det a determiner, Adj an adjective, Adv an adverb, P a preposition, NP a noun phrase, PP a prepositional phrase, VP a verb phrase, VG a verb group, and REL is the target relation. Notice, that the grammar does not consider coordinating conjunctions, e.g. with "and", "or" and ",".
