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__
