public class XPNPC

extends Object

Contains numerous PNPCs which it uses to determine the probable classification of different types of words. In particular, contains one PNPC for each word type (e.g., NNP, VP, ...). The PNPC for each word type has a category for each possible tag combination (e.g, NNP[{}], NNP[{purchaser}], ...).

Constructor Summary

XPNPC(List lexicon)
creates a new XPNPC.

Method Summary

List	GetLexicon(Tree tree) Calculates a probability for each lexical rule that may have been used to generate this tree.
static void	main(String[] args) tests the XPNPC functionality.

Method Detail

GetLexicon

public List GetLexicon(Tree tree)
                throws IOException

Calculates a probability for each lexical rule that may have been used to generate this tree. Process: 1) Lists all of the untagged lexical rules used to generate the tree. 2) Expands untagged lexical rules into lexical rules (e.g., NNP -> "Amazon" become {NNP[{}] -> "Amazon", NNP[{purchaser}] -> "Amazon", ...}
