Method Details [hide private]

__init__(self, tokens)
(Constructor)

source code 

Construct a new chart. The chart is initialized with the leaf edges corresponding to the terminal leaves.

Parameters:
  • tokens - The sentence that this chart will be used to parse.
Overrides: parse.chart.Chart.__init__
(inherited documentation)

_trees(self, edge, complete, memo, tree_class)

source code 

A helper function for trees.

Parameters:
  • memo - A dictionary used to record the trees that we've generated for each edge, so that when we see an edge more than once, we can reuse the same trees.
Overrides: parse.chart.Chart._trees
(inherited documentation)
