nltk.chunk.regexp.StripRule

class documentation

class StripRule(RegexpChunkRule): (source)

Constructor: StripRule(tag_pattern, descr)

A rule specifying how to remove strips 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 contained in a chunk, and remove it from that chunk, thus creating two new chunks.

Method	`__init__`	Construct a new `StripRule`.
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__

Construct a new StripRule.

Parameters
tag_pattern:str	This rule's tag pattern. When applied to a `ChunkString`, this rule will find any substring that matches this tag pattern and that is contained in a chunk, and remove it from that chunk, thus creating two new chunks.
descr:str	A short description of the purpose and/or effect of this rule.

def __repr__(self): (source) ¶

overrides nltk.chunk.regexp.RegexpChunkRule.__repr__

Return a string representation of this rule. It has the form:

<StripRule: '<IN|VB.*>'>

Note that this representation does not include the description string; that string can be accessed separately with the descr() method.

Returns
