combineNouns

protected abstract void combineNouns(HAWKQuestion q)

This sets compound nouns as Entity in question. No changes to MutableTree.

 Note: This expects expects HAWKquestion already to be dependency
  parsed, e.g. a MutableTree with annotated Nodes is set.

 Use #combineNounsOnNew(HAWKQuestion) to get a new processed tree,
 without affecting HAWKQuestion

 Use processTree(HAWKQuestion) to prune all found CombinedNNs
 in MutbaleTree directly in HAWKQuestion
 

Parameters:

q - HAwkquestion to process

processTree

protected static void processTree(HAWKQuestion q)

Compound nouns are spread over multiple Nodes in MutableTree. This will be reduced to one Node, which has "CombinedNN" as POS tag, as label all labels from this noun combined. HAWKQuestion.getLanguageToNounPhrases() is used to find Nodes to combine. Be sure to set combinedNouns there using combineNouns(HAWKQuestion) beforehand.

Parameters:

q - HAWKQuestion to process

protected static void setEntity(List<String> subsequence,
                                HAWKQuestion q,
                                int subsequenceStartOffset)
