udpipe_annotate: Tokenising, Lemmatising, Tagging and Dependency Parsing Annotation of raw text

Description

Tokenising, Lemmatising, Tagging and Dependency Parsing Annotation of raw text

Usage

udpipe_annotate(
  object,
  x,
  doc_id = paste("doc", seq_along(x), sep = ""),
  tokenizer = "tokenizer",
  tagger = c("default", "none"),
  parser = c("default", "none"),
  trace = FALSE,
  ...
)

Value

a list with 3 elements

• x: The x character vector with text.

• conllu: A character vector of length 1 containing the annotated result of the annotation flow in CONLL-U format. This format is explained at https://universaldependencies.org/format.html

• error: A vector with the same length of x containing possible errors when annotating x

Arguments

object

an object of class udpipe_model as returned by udpipe_load_model

x

a character vector in UTF-8 encoding where each element of the character vector contains text which you like to tokenize, tag and perform dependency parsing.

doc_id

an identifier of a document with the same length as x. This should be a character vector. doc_id[i] corresponds to x[i].

tokenizer

a character string of length 1, which is either 'tokenizer' (default udpipe tokenisation) or a character string with more complex tokenisation options as specified in https://ufal.mff.cuni.cz/udpipe/1/users-manual in which case tokenizer should be a character string where the options are put after each other using the semicolon as separation.

tagger

a character string of length 1, which is either 'default' (default udpipe POS tagging and lemmatisation) or 'none' (no POS tagging and lemmatisation needed) or a character string with more complex tagging options as specified in https://ufal.mff.cuni.cz/udpipe/1/users-manual in which case tagger should be a character string where the options are put after each other using the semicolon as separation.

parser

a character string of length 1, which is either 'default' (default udpipe dependency parsing) or 'none' (no dependency parsing needed) or a character string with more complex parsing options as specified in https://ufal.mff.cuni.cz/udpipe/1/users-manual in which case parser should be a character string where the options are put after each other using the semicolon as separation.

trace

A non-negative integer indicating to show progress on the annotation. If positive it prints out a message before each trace number of elements of x for which annotation is to be executed, allowing you to see how much of the text is already annotated. Defaults to FALSE (no progress shown).

## Only tokenisation
x <- udpipe_annotate(ud_dutch, x = txt, tagger = "none", parser = "none")
as.data.frame(x)

## Only tokenisation and POS tagging + lemmatisation, no dependency parsing
x <- udpipe_annotate(ud_dutch, x = txt, tagger = "default", parser = "none")
as.data.frame(x)

## Only tokenisation and dependency parsing, no POS tagging nor lemmatisation
x <- udpipe_annotate(ud_dutch, x = txt, tagger = "none", parser = "default")
as.data.frame(x)

## Provide doc_id for joining and identification purpose
x <- udpipe_annotate(ud_dutch, x = txt, doc_id = c("id1", "feedbackabc"),
                     tagger = "none", parser = "none", trace = TRUE)
as.data.frame(x)

## Mark on encodings: if your data is not in UTF-8 encoding, make sure you convert it to UTF-8 
## This can be done using iconv as follows for example
udpipe_annotate(ud_dutch, x = iconv('Ik drink melk bij mijn koffie.', to = "UTF-8"))
}



## cleanup for CRAN only - you probably want to keep your model if you have downloaded it
if(file.exists(model$file_model)) file.remove(model$file_model)
