Method Detail

headFinder

public HeadFinder headFinder()

returns a NegraHeadFinder

Specified by:

headFinder in interface TreebankLangParserParams

Specified by:

headFinder in class AbstractTreebankParserParams

typedDependencyHeadFinder

public HeadFinder typedDependencyHeadFinder()

Description copied from class: AbstractTreebankParserParams

The HeadFinder to use when extracting typed dependencies.

Specified by:

typedDependencyHeadFinder in interface TreebankLangParserParams

Specified by:

typedDependencyHeadFinder in class AbstractTreebankParserParams

lex

public Lexicon lex(Options op,
                   Index<java.lang.String> wordIndex,
                   Index<java.lang.String> tagIndex)

returns an ordinary Lexicon (could be tuned for German!)

Specified by:

lex in interface TreebankLangParserParams

Overrides:

lex in class AbstractTreebankParserParams

Parameters:

op - Options as to how the Lexicon behaves

Returns:

A Lexicon, constructed based on the given option

treeReaderFactory

public TreeReaderFactory treeReaderFactory()

Description copied from interface: TreebankLangParserParams

Returns a factory for reading in trees from the source you want. It's the responsibility of trf to deal properly with character-set encoding of the input. It also is the responsibility of trf to properly normalize trees.

Returns:

A factory that vends an appropriate TreeReader

memoryTreebank

public MemoryTreebank memoryTreebank()

Description copied from class: AbstractTreebankParserParams

returns a MemoryTreebank appropriate to the treebank source

Specified by:

memoryTreebank in interface TreebankLangParserParams

Specified by:

memoryTreebank in class AbstractTreebankParserParams

diskTreebank

public DiskTreebank diskTreebank()

Description copied from class: AbstractTreebankParserParams

returns a DiskTreebank appropriate to the treebank source

Specified by:

diskTreebank in interface TreebankLangParserParams

Specified by:

diskTreebank in class AbstractTreebankParserParams

collinizer

public TreeTransformer collinizer()

returns a NegraPennCollinizer

Specified by:

collinizer in interface TreebankLangParserParams

Specified by:

collinizer in class AbstractTreebankParserParams

Returns:

A TreeTransformer that performs adjustments to trees to delete or equivalence class things not evaluated in the parser performance evaluation.

collinizerEvalb

public TreeTransformer collinizerEvalb()

returns a NegraPennCollinizer

Specified by:

collinizerEvalb in interface TreebankLangParserParams

Specified by:

collinizerEvalb in class AbstractTreebankParserParams

sisterSplitters

public java.lang.String[] sisterSplitters()

Description copied from class: AbstractTreebankParserParams

Returns the splitting strings used for selective splits.

Specified by:

sisterSplitters in interface TreebankLangParserParams

Specified by:

sisterSplitters in class AbstractTreebankParserParams

Returns:

An array containing ancestor-annotated Strings: categories should be split according to these ancestor annotations.

setOptionFlag

public int setOptionFlag(java.lang.String[] args,
                         int i)

Set language-specific options according to flags. This routine should process the option starting in args[i] (which might potentially be several arguments long if it takes arguments). It should return the index after the last index it consumed in processing. In particular, if it cannot process the current option, the return value should be i.

Specified by:

setOptionFlag in interface TreebankLangParserParams

Overrides:

setOptionFlag in class AbstractTreebankParserParams

Parameters:

args - Array of command line arguments

i - Index in command line arguments to try to process as an option

Returns:

The index of the item after arguments processed as part of this command line option.

display

public void display()

Description copied from class: AbstractTreebankParserParams

display language-specific settings

Specified by:

display in interface TreebankLangParserParams

Specified by:

display in class AbstractTreebankParserParams

transformTree

public Tree transformTree(Tree t,
                          Tree root)

transformTree does all language-specific tree transformations. Any parameterizations should be inside the specific TreebankLangParserarams class.

Specified by:

transformTree in interface TreebankLangParserParams

Specified by:

transformTree in class AbstractTreebankParserParams

Parameters:

t - The input tree (with non-language specific annotation already done, so you need to strip back to basic categories)

root - The root of the current tree (can be null for words)

Returns:

The fully annotated tree node (with daughters still as you want them in the final result)

defaultTestSentence

public java.util.List<? extends HasWord> defaultTestSentence()

Return a default sentence for the language (for testing)

Returns:

A default sentence of the language
