The input doesn't matter. Must be instantiated with a complete set of tags. The tag list should contain lists of tags for each word (usually each list will contain just one item). These are what it will return.

__init__(self, grammar, input, options={}, tags=None)
The tagger must have reference to the grammar being used to parse the input.

get_word(self, index)
Returns the input word at this index.

Method Details [hide private]

__init__(self, grammar, input, options={}, tags=None)
(Constructor)

source code 

The tagger must have reference to the grammar being used to parse the input. It must also be given the full input when instantiated. The format of this input will depend on the tagger: for example, it might be a string or a MIDI file.

Parameters:
  • original_input - the input in its original, unprocessed form. This will usually be a string. This is optional, but in some circumstances things might fall apart if it hasn't been given. E.g. using a backoff model as backoff from a tagging model requires the original input to be passed to the backoff model.
  • logger - optional progress logger. Logging will be sent to this during initialization of the tagger and tagging. If not given, the logging will be lost. Subclasses may access the logger (or a dummy logger if none was given) in self.logger.
Overrides: object.__init__
(inherited documentation)

get_word(self, index)

source code 

Returns the input word at this index. This does not need to be a string, but must have a sensible __str__, so that it can be converted to a readable string. The purpose of this is to provide a readable form of the input for the parser to store in derivation traces.

Overrides: tagger.Tagger.get_word
