Known Subclasses:: RegexpChunk

A processing interface for identifying non-overlapping groups in unrestricted text. Typically, chunk parsers are used to find base syntactic constituants, such as base noun phrases. Unlike ParseI, ChunkParseI guarantees that the parse method will always generate a parse.

Method Summary
	`parse(self, tokens)` Find the best chunk structure for the given tokens and return a tree
	`parse_n(self, tokens, n)` Find a list of the `n` most likely chunk structures for the tokens, and return a tree.
Inherited from `ParseI`: `get_parse`, `get_parse_list`, `get_parse_probs` Inherited from `object`: `__init__`, `__delattr__`, `__getattribute__`, `__hash__`, `__new__`, `__reduce__`, `__reduce_ex__`, `__repr__`, `__setattr__`, `__str__`

Method Details

parse(self, tokens)

Find the best chunk structure for the given tokens and return a tree

Parameters:: tokens - The list of (word, tag) tokens to be chunked.
(type=list of tuple)

Overrides:: nltk_lite.parse.ParseI.parse

parse_n(self, tokens, n=None)

Find a list of the n most likely chunk structures for the tokens, and return a tree. If there are fewer than n chunk structures, then find them all. The chunk structures should be stored in descending order of estimated likelihood.

Parameters:: tokens - The list of (word, tag) tokens to be chunked.
(type=list of tuple); n - The number of chunk structures to generate. At most n chunk structures will be generated. If n is not specified, generate all chunk structures.
(type=int)
