All Implemented Interfaces:

Serializable

public class NPTmpRetainingTreeNormalizer
extends BobChrisTreeNormalizer

Same TreeNormalizer as BobChrisTreeNormalizer, but optionally provides four extras. I.e., the class name is now a misnomer.
1) retains -TMP labels on NP with the new identification NP-TMP, and provides various options to percolate that option downwards to the head noun, and perhaps also to inherit this from a PP-TMP.
2) Annotates S nodes which contain a gapped subject: i.e., S < (/^NP-SBJ/ < -NONE-) --> S-G
3) Leave all functional tags on nodes.
4) Keeps -ADV labels on NP and marks head tag with &`^ADV

Performance note: At one point in time, PCFG labeled F1 results for the various TEMPORAL options in lexparser were: 0=86.7, 1=87.49, 2=86.87, 3=87.49, 4=87.48, 5=87.5, 6=87.07. So, mainly avoid values of 0, 2, and 6.

At another point they were: 0=86.53, 1=87.1, 2=87.14, 3=87.22, 4=87.1, 5=87.13, 6=86.95, 7=87.16

Create a TreeNormalizer that maintains some functional annotations, particularly those involving temporal annotation.

Parameters:

temporalAnnotation - One of the constants: TEMPORAL_NONE (no temporal annotation kept on trees), TEMPORAL_ACL03PCFG (temporal annotation on NPs, and percolated down to head of constituent until and including POS tag), TEMPORAL_ANY_TMP_PERCOLATED (temporal annotation on any phrase is kept and percolated via head chain to and including POS tag), TEMPORAL_ALL_TERMINALS (temporal annotation is kept on NPs, and is placed on all POS tag daughters of that NP (but is not percolated down a head chain through phrasal categories), TEMPORAL_ALL_NP (temporal annotation on NPs, and it is percolated down via the head chain, but only through NPs: annotation stops at either a POS tag (which is annotated) or a non-NP head (which isn't annotated)), TEMPORAL_ALL_NP_AND_PP (keeps temporal annotation on NPs and PPs, and it is percolated down via the head chain, but only through NPs: annotation stops at either a POS tag (which is annotated) or a non-NP head (which isn't annotated)). TEMPORAL_NP_AND_PP_WITH_NP_HEAD (like TEMPORAL_ALL_NP_AND_PP except an NP is regarded as the head of a PP) TEMPORAL_ALL_NP_EVEN_UNDER_PP (like TEMPORAL_ALL_NP, but a PP-TMP annotation above an NP is 'passed down' to annotate that NP as temporal (but the PP itself isn't marked)) TEMPORAL_ALL_NP_PP_ADVP (keeps temporal annotation on NPs, PPs, and ADVPs and it is percolated down via the head chain, but only through NPs: annotation stops at either a POS tag (which is annotated) or a non-NP head (which isn't annotated)).

headFinder - A head finder that is used with some of the options for temporalAnnotation

Method Detail

cleanUpLabel

protected String cleanUpLabel(String label)

Remove things like hyphened functional tags and equals from the end of a node label.

Overrides:

cleanUpLabel in class BobChrisTreeNormalizer

normalizeWholeTree

public Tree normalizeWholeTree(Tree tree,
                               TreeFactory tf)

Normalize a whole tree -- one can assume that this is the root. This implementation deletes empty elements (ones with nonterminal tag label '-NONE-') from the tree.

Overrides:

normalizeWholeTree in class BobChrisTreeNormalizer

Parameters:

tree - The tree to be normalized

tf - the TreeFactory to create new nodes (if needed)

Returns:

Tree the normalized tree
