nounphrase_extract: Extract or consolidate noun phrases from parsed documents

Description

From an object parsed by spacy_parse(), extract the multi-word noun phrases as a separate object, or convert the multi-word noun phrases into single "token" consisting of the concatenated elements of the multi-word noun phrases.

Usage

nounphrase_extract(x, concatenator = "_")
nounphrase_consolidate(x, concatenator = "_")

Value

noun returns a data.frame of all named entities, containing the following fields:

• doc_id name of the document containing the noun phrase

• sentence_id the sentence ID containing the noun phrase, within the document

• nounphrase the noun phrase

• root the root token of the noun phrase

nounphrase_consolidate returns a modified data.frame of parsed results, where the noun phrases have been combined into a single "token". Currently, dependency parsing is removed when this consolidation occurs.

Arguments

x

output from spacy_parse()

concatenator

the character(s) used to join elements of multi-word noun phrases
