subset_nodes(.tokens, subset, copy = TRUE)
.tokens |
A tokenIndex in which nodes are selected with select_nodes. |
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$column. |
copy |
If TRUE, make a deep copy of .tokens. Use if output does not overwrite .tokens |
A tokenIndex with a .nodes attribute
tokens = tokens_spacy[tokens_spacy$doc_id == 'text4',] ## use a tquery to label the nodes that you want to manipulate tq = tquery(label='verb', children(relation='nsubj')) ## apply query to select nodes tokens2 = select_nodes(tokens, tq) selected_nodes(tokens2)$nodes tokens2 = subset_nodes(tokens2, verb$relation == 'ROOT') selected_nodes(tokens2)$nodes
