nltk.chunk.regexp.ChunkRule

class documentation

class ChunkRule(RegexpChunkRule): (source)

Constructor: ChunkRule(tag_pattern, descr)

A rule specifying how to add chunks to a ChunkString, using a matching tag pattern. When applied to a ChunkString, it will find any substring that matches this tag pattern and that is not already part of a chunk, and create a new chunk containing that substring.

Method	`__init__`	Construct a new `ChunkRule`.
Method	`__repr__`	Return a string representation of this rule. It has the form:
Instance Variable	`_pattern`	Undocumented

Inherited from RegexpChunkRule:

Static Method	`fromstring`	Create a RegexpChunkRule from a string description. Currently, the following formats are supported:
Method	`apply`	Apply this rule to the given `ChunkString`. See the class reference documentation for a description of what it means to apply a rule.
Method	`descr`	Return a short description of the purpose and/or effect of this rule.
Instance Variable	`_descr`	Undocumented
Instance Variable	`_regexp`	Undocumented
Instance Variable	`_repl`	Undocumented

def __init__(self, tag_pattern, descr): (source) ¶

overrides nltk.chunk.regexp.RegexpChunkRule.__init__

tag_pattern:str	This rule's tag pattern. When applied to a `ChunkString`, this rule will chunk any substring that matches this tag pattern and that is not already part of a chunk.

def __repr__(self): (source) ¶

overrides nltk.chunk.regexp.RegexpChunkRule.__repr__
