The CYK-Parser takes 5 arguments:
1. args[0] the path to the grammar file
2. args[1] the path to the lexicon file
3. args[2] the startsymbol
4. args[3] the input string
5. args[4] the number of parses one wants to see printed to the console
- if args[4] > the total amount of parses
- then total amount of parses is printed to the console
- without a warning that the user typed in a greater number than expected
-----------------------------------------------------------------------------------------------------------------------------------------------
The output is of the form:
Total number of parses: 10
Number of parses shown: 1
(This is the actual parse in a more readable way: the "prettyParse" method is responsible for the transformation)
S [ADV [soon] S [NP [DET [the] N [man]] VP [VP [V [drinks] NP [NP [DET [an] N [espresso]] PP [P [on] NP [DET [the] N [table]]]]] ADV [later]]]]
(Those are the corresponding rules which were applied to get the parse above: the "showRules" method is responsible for extracting the rules out of
the parse above)
