_create_chart(self, *args, **kwargs)

source code

list of tuples

_add_signs(self, offset)
Adds new signs to the chart from the supertagger, using the given offset when requesting them from the tagger.

source code

parse(self, *args, **kwargs)

_create_chart(self, *args, **kwargs)

source code

Overrides: cky.parser.CkyParser._create_chart

_add_signs(self, offset)

source code

Adds new signs to the chart from the supertagger, using the given offset when requesting them from the tagger.

Returns: list of tuples: all the signs that were actually added. Each is represented by a tuple (start_node, end_node, sign)
Overrides: cky.parser.CkyParser._add_signs: (inherited documentation)

parse(self, *args, **kwargs)

source code

Performs a full parse and returns the results ranked by a product of their tag probabilities.

Parameters:

derivations - store derivation traces, which can subsequently be used to trace all the derivations that led to any given sign in the chart. Overridden by the module option if it's given
summaries - output chart summary information to stderr during parsing to track progress. Set to 2 to output some info, but not the full chart.
inspect - launch a graphical chart inspector during the parse to display interactive chart information.

Returns:

a list of signs that span the full input.

Overrides: base.parser.Parser.parse
