NAME

DTA::TokWrap::Processor::tcfdecode0 - DTA tokenizer wrappers: TCF[tei,text,tokens,sentences]->TEI,text extraction

SYNOPSIS

use DTA::TokWrap::Processor::tcfdecode0;

$dec = DTA::TokWrap::Processor::tcfdecode0->new(%opts);
$doc_or_undef = $dec->tcfdecode0($doc);

DESCRIPTION

DTA::TokWrap::Processor::tcfdecode0 provides an object-oriented DTA::TokWrap::Processor wrapper for extracting the tei,text,tokens, and sentences layers from a tokenized TCF ("Text Corpus Format", cf. http://weblicht.sfs.uni-tuebingen.de/weblichtwiki/index.php/The_TCF_Format) document as originally encoded by a DTA::TokWrap::Processor::tcfencode ("tcfencoder") object. The encoded TCF document should have the following layers:

textSource[@type="application/tei+xml"]

Source TEI-XML encoded as an XML text node; should be identical to the source XML {xmlfile} or {xmldata} passed to the tcfencoder. Also accepts type "text/tei+xml".

text

Serialized text encoded as an XML text node; should be identical to the serialized text {txtfile} or {txtdata} passed to the tcfencoder.

tokens

Tokens returned by the tokenizer for the text layer. Document order of tokens should correspond exactly to the serial order of the associated text in the text layer.

sentences

Sentences returned by the tokenizer for the tokens in the tokens layer. Document order of sentences must correspond exactly to the serial order of the associated text in the text layer.

The following additional layers will be decoded if the decode_tcfa option is set to a true value:

lemmas

TCF lemmata identified by tokenIDs in 1:1 correspondence with the tokens in the tokens layer.

POStags

TCF part-of-speech tags identified by tokenIDs in 1:1 correspondence with the tokens in the tokens layer.

orthography

TCF orthographic normalizations (replace operations only) identified by tokenIDs in 1:1 correspondence with the tokens in the tokens layer.

Constants

@ISA

DTA::TokWrap::Processor::tcfdecode0 inherits from DTA::TokWrap::Processor.

Constructors etc.

new
$obj = $CLASS_OR_OBJECT->new(%args);

Constructor. Default %args:

decode_tcfx => $bool,  ##-- whether to decode $tcfxdata (default=1)
decode_tcft => $bool,  ##-- whether to decode $tcftdata (default=1)
decode_tcfw => $bool,  ##-- whether to decode $tcfwdata (default=1)
decode_tcfa => $bool,  ##-- whether to decode $tcfadata (default=1)
defaults
%defaults = $CLASS->defaults();

Static class-dependent defaults.

Methods

tcfdecode0
$doc_or_undef = $CLASS_OR_OBJECT->tcfdecode0($doc);

Decode0s the {tcfdoc} key of the DTA::TokWrap::Document object to TCF, storing the result in $doc->{tcfxdata}, $doc->{tcftdata}, and $doc->{tcfwdata}.

Relevant %$doc keys:

tcfdoc   => $tcfdoc,   ##-- (input) TCF input document
##
tcfxdata => $tcfxdata, ##-- (output) TEI-XML decode0d from TCF
tcftdata => $tcftdata, ##-- (output) text data decode0d from TCF
tcfwdata => $tcfwdata, ##-- (output) tokenized data decode0d from TCF, without byte-offsets, with "SID/WID" attributes
tcfadata => $tcfadata, ##-- (output) annotation data decode0d from TCF
##
tcfdecode0_stamp0 => $f, ##-- (output) timestamp of operation begin
tcfdecode0_stamp  => $f, ##-- (output) timestamp of operation end
tcfxdata_stamp   => $f, ##-- (output) timestamp of operation end
tcftdata_stamp   => $f, ##-- (output) timestamp of operation end
tcfwdata_stamp   => $f, ##-- (output) timestamp of operation end
tcfadata_stamp   => $f, ##-- (output) timestamp of operation end
