> Phrase Chunker
Phrase chunking is to group words into word groups known as phrases. Typical chunks are noun phrase (NP) and verb phrase (VP). Noun phrase can consist of one or more adjectives and a noun/pronoun. A typical verb phrase can consist of a main verb, operator verbs, and an auxiliary verb.A phrase chunker (also simply known as a chunker) assigns tags to the word sequences in a sentence.
A phrase tag, similar to a POS tag, is an abbreviated form of the phrase class (and optional grammatical information). For instance, in this phrase tagger ‘NPD’ tag is used for noun phrase (NP) having head word (noun/pronoun) in direct (D) case. Like POS taggers, most of the phrase chunkers use similar tags. However, the number of tags in a chunker depends upon its application area.
