copy_fill: Copy nodes

In rsyntax: Extract Semantic Relations from Text by Querying and Reshaping Syntax

Copy nodes

Description

Copy nodes

Usage

copy_fill(
  .tokens,
  from_node,
  to_node,
  subset = NULL,
  subset_fill = NULL,
  only_new = NULL
)

Arguments

.tokens	A tokenIndex in which nodes are selected with select_nodes.
from_node	The name of the node from which fill is copied
to_node	The name of the node to which fill is copied
subset	A subset expression (that evaluates to a logical vector). The token column for each labeled node in the tquery can be referred to as label$column.
subset_fill	A subset on the fill nodes. Can only directly use token column. For example, use pos == 'VERB' to copy only verbs
only_new	If TRUE, direct fill children will only be copied to to_node if it does not already have nodes of this relation. This is a good heuristic for dealing with argument drop.

Value

A tokenIndex with a .nodes attribute

Examples

tokens = tokens_spacy[tokens_spacy$doc_id == 'text1',]

tq = tquery(label='object', relation='dobj')
            
tokens2 = select_nodes(tokens, tq)
selected_nodes(tokens2)

tokens3 = copy_nodes(tokens2, 'object', 'new_object')
copy_fill(tokens3, 'object', 'new_object')
