entity_extract {spacyr} | R Documentation |
Extract or consolidate entities from parsed documents
Description
From an object parsed by spacy_parse()
, extract the entities as a
separate object, or convert the multi-word entities into single "token"
consisting of the concatenated elements of the multi-word entities.
Usage
entity_extract(x, type = c("named", "extended", "all"), concatenator = "_")
entity_consolidate(x, concatenator = "_")
Arguments
x |
output from |
type |
type of named entities, either |
concatenator |
the character(s) used to join the elements of multi-word named entities |
Value
entity_extract()
returns a data.frame of all named
entities, containing the following fields:
-
doc_id
name of the document containing the entity -
sentence_id
the sentence ID containing the entity, within the document -
entity
the named entity -
entity_type
the type of named entities (e.g. PERSON, ORG, PERCENT, etc.)
entity_consolidate
returns a modified data.frame
of
parsed results, where the named entities have been combined into a single
"token". Currently, dependency parsing is removed when this consolidation
occurs.
