Document Diversity Annotator
Description
Generate an annotator which computes document diversity annotations
for English documents using diversity() from package
qdap.
Usage
QDAP_Diversity_Annotator()
Value
A Annotator object giving the generated document
diversity annotator.
Examples
require("NLP")
doc <- readRDS(system.file("texts", "stanford.rds", package = "NLP"))
s <- content(doc)
a <- annotation(doc)
diversity_annotator <- QDAP_Diversity_Annotator()
diversity_annotator(s, a)
Document Formality Annotator
Description
Generate an annotator which computes document formality annotations
for English documents using formality() from package
qdap.
Usage
QDAP_Formality_Annotator()
Value
A Annotator object giving the generated document
formality annotator.
Examples
require("NLP")
doc <- readRDS(system.file("texts", "stanford.rds", package = "NLP"))
s <- content(doc)
a <- annotation(doc)
formality_annotator <- QDAP_Formality_Annotator()
formality_annotator(s, a)
Sentence Polarity Annotator
Description
Generate an annotator which computes sentence polarity annotations for
English documents using polarity() from package
qdap.
Usage
QDAP_Polarity_Annotator()
Value
A Annotator object giving the generated sentence
polarity annotator.
Examples
require("NLP")
doc <- readRDS(system.file("texts", "stanford.rds", package = "NLP"))
s <- content(doc)
a <- annotation(doc)
polarity_annotator <- QDAP_Polarity_Annotator()
polarity_annotator(s, a)

wordStem() from package SnowballC.
Usage
Snowball_Stem_Annotator(language = "porter")
Arguments
language |
a character string giving the document language.
See the documentation for |
Value
A Annotator object giving the generated word stem
annotator.
Examples
require("NLP")
doc <- readRDS(system.file("texts", "stanford.rds", package = "NLP"))
