NAME
frog - Dutch Natural Language Toolkit
SYNOPSIS
frog [options]
frog -t test-file
DESCRIPTION
Frog is an integration of memory‐-based natural language processing (NLP) modules
developed for Dutch. Frog's current version will (optionally) tokenize, tag, lemmatize,
and morphologically segment word tokens in Dutch text files, add IOB chunks, add Named
Entities and will assign a dependency graph to each sentence.
OPTIONS
-c <file> or --config=<file>
set the configuration using 'file'.
you can use -c lang/config-file to select the 'config-file' for an installed
language 'lang'
--debug=<modele><level>,...
set debug level per module, indicated by a single letter: Tagger (T), Tokenizer
(t), Lemmatizer (l), Morphological Analyzer (a), Chunker (c), Multi‐Word Units (m),
Named Entity Recognition (n), or Parser (p). Different modules must be separated by
commas.
(e.g. --debug=l5,n3 sets the level for the Lemmatizer to 5 and for the NER to 3 )
-d <level>
set global debug level. (for all modules)
--deep‐morph
generate a deep morphological analysis and add it to the XML. This also includes
compound information. The default 'Tabbed' and JSON output is also more detailed
in the Morpheme field.
-e <encoding>
set input encoding. (default UTF8)
-h or --help
give some help
--language=<comma separated list of languages>
Set the languages to work on. This parameter is passed to the tokenizer. The
strings are assumed to be ISO 639-2 codes.
The first language in the list will be the default, unspecified languages are
asumed to be of that default.
e.g. --language=nld,eng,por means: detect Dutch, English and Portuguese, with Dutch
being the default.
IMPORTANT Frog can at the moment handle only one language at a time, as determined
by the config file. So other languages mentioned here will be tokenized correctly,
but further they will be handled as that language.
-n
assume inputfile to have one sentence per line. (newline separators)
Very useful when running interactive, otherwise an empty line is needed to signal
end of input.
--nostdout
suppress the 'Tabbed' or JSON output to stdout. (when no outputfile was specified
with -o or --outputdir)
Especially useful when XML output is specified with -X or --xmldir.
-o <file>
send 'Tabbed' output to 'file' instead of stdout. Defaults to the name of the
inputfile with '.out' appended.
--outputdir <dir>
send all 'Tabbed' or JSON output to 'dir' instead of stdout. Creates filenames from
the inputfilename(s) with '.out' appended.
--retry
assume a re-run on the same input file(s). Frog wil only process those files that
haven't been processed yet. This is accomplished by looking at the output file
names. (so this has no effect if neither -o, --outputdir, -X or --xmldir is used)
--skip=[tlacnmp]
skip parts of the process: Tokenizer (t), Lemmatizer (l), Morphological Analyzer
(a), Chunker (c), Named Entity Recognition (n), Multi-Word Units (m) or Parser (p).
Skipping the Multiword Unit implies disabling the Parser too.
--alpino
Use a locally installed Alpino parser
--alpino=server
use a remote installed Alpino server, as specified in the frog configuration file.
-S <port>
Run Frog as a server on 'port'
-t <file>
process 'file'.
-t can be omitted. Frog will run on any <file> found on the command-line.
Wildcards are allowed too. When NO files are specied, Frog will start in
interactive mode.
-x <xmlfile>
process 'xmlfile', which is supposed to be in FoLiA format! If 'xmlfile' is empty,
and --testdir=<dir> is provided, all '.xml' files in 'dir' will be processed as
FoLia XML.
-X <xmlfile>
When 'xmlfile' is specified, create a FoLiA XML output file with that name.
When 'xmlfile' is empty, generate XML output for every inputfile.
--textclass=<cls>
When -x is given, use 'cls' to find AND store text in the FoLiA document(s). Using
--inputclass and --ptclass is in general a better choice.
--inputclass=<cls>
use 'cls' to find text in the FoLiA input document(s).
--outputclass=<cls>
use 'cls' to output text in the FoLiA input document(s). Preferably this is
another class then the inputclass.
--testdir=<dir>
process all files in 'dir'. When the input mode is XML, only '.xml' files are teken
from 'dir'. see also --outputdir
--tmpdir=<dir>
location to store intermediate files. Default /tmp. NOT USED!
--uttmarker=<mark>
assume all utterances are separated by 'mark'. (the default is none).
--threads=<n>
use a maximum of 'n' threads. The default is to take whatever is needed. In
servermode we always run on 1 thread per session.
-V or --version
show version info
--xmldir=<dir>
generate FoLiA XML output and send it to 'dir'. Creates filenames from the
inputfilename with '.xml' appended. (Except when it already ends with '.xml')
-X <file>
generate FoLiA XML output and send it to 'file'. Defaults to the name of the
inputfile(s) with '.xml' appended. (Except when it already ends with '.xml')
--id=<id>
When -X for FoLia is given, use 'id' to give the doc an ID. The default is an
xml:id based on the filename.
--allow-word-corrections
Allow the ucto tokenizer to apply simple corrections on words while processing
FoLiA output. For instance splitting punctuation.
--max-parser-tokens=<num>
Limit the size of sentences to be handled by the Parser. (Default 500 words).
The Parser is very memory consuming. 500 Words will already need 16Gb of RAM.
--JSONin
The input is in JSON format. Mainly for Server mode, but works on files too.
This implies --JSONout too!
--JSONout
Output will be in JSON instead of 'Tabbed'.
--JSONout=<indent>
Output will be in JSON instead of 'Tabbed'. The JSON will be idented by value
'indent'. (Default is indent=0. Meaning al the JSON will be on 1 line)
-T or --textredundancy=[full|medium|none]
Set the text redundancy level in the tokenizer for text nodes in FoLiA output: full
add text to all levels: <p> <s> <w> etc. minimal don't introduce text on higher
levels, but retain what is already there. none only introduce text on <w>, AND
remove all text from higher levels
--override=<section>.<parameter>=<value>
Override a parameter from the configuration file with a different value.
This option may be repeated several times.
