(grammar, strategy=[<nltk.parse.chart.LeafInitRule object at 0x2b21a94fb150>, <nltk.parse.chart.EmptyPredictRule object at 0x2b21a94fb190>, <nltk.parse.chart.BottomUpPredictCombineRule object at 0x2b21a94fb1d0>, <nltk.parse.earleychart.CompleteFundamentalRule object at 0x2b21a94fb210>], trace=0, trace_chart_width=50, chart_class=<class 'nltk.parse.earleychart.IncrementalChart'>)[source]¶ Create a new Earley chart parser, that uses
grammar
to parse texts.Parameters: - grammar (CFG) – The grammar used to parse texts.
- trace (int) – The level of tracing that should be used when
parsing a text.
0
will generate no tracing output; and higher numbers will produce more verbose tracing output. - trace_chart_width (int) – The default total width reserved for the chart in trace output. The remainder of each line will be used to display edges.
- chart_class – The class that should be used to create the charts used by this parser.
