treetagger.docker

This repository contains docker images to build and ship ready to use TreeTagger instances.

You will not have to manually install TreeTagger in your system again.

What it is

A tool for annotating text with part-of-speech (POS tagging) and lemma information.

TreeTagger consists of two programs:

1. train-tree-tagger

   Creates a parameter file from a lexicon and a handtagged corpus.

2. tree-tagger

   Annotates the text with part-of-speech tags, given a parameter file and a text file as arguments.

This image contains:

• training program and tagger executables

• program for tokenization (i.e., separate-punctuation)

• shell scripts (shortcuts) which simplify tagging and chunking:

  e.g., tree-tagger-italian, tree-tagger-german, tagger-chunker-english, ...

• parameter files, chunker parameter files, and abbreviations files

• documentaion and language tagsets references

See yourself them:

$ docker run -i -t leodido/treetagger ls /usr/local

At this link the offical page and further documentation.

Installation

Directly pull this image from the docker index.

$ docker pull leodido/treetagger

Usage

Tagging

Suppose you want to (tokenize and) tag an Italian text.

The script to use is tree-tagger-italian.

It expects UTF8 encoded input files as arguments. If no files have been specified, input from stdin is expected.

$ echo 'Proviamo semplicemente a eseguire un test di prova.' | docker run --rm -i leodido/treetagger tree-tagger-italian

Outputs:

Proviamo	    VER:pres	provare
semplicemente	ADV	        semplicemente
a	            PRE	        a
eseguire	    VER:infi	eseguire
un	            DET:indef	un
test	        NOM	        test
di	            PRE	        di
prova	        NOM	        prova
.	            SENT	    .

Now, try with some Portuguese.

$ echo 'Qual é o seu nome?' | docker run --rm -i leodido/treetagger tree-tagger-portuguese

Results:

Qual	PT0	    qual
é	     VMI	 ser
o	    DA0	    o
seu	    DP3	    seu
nome	NCMS	nome
?	    Fit	    ?

Finegrained?

$ echo 'Qual é o seu nome?' | docker run --rm -i leodido/treetagger tree-tagger-portuguese-finegrained

Results:

Qual	PT0CS000	qual
é       VMIP3S0	 ser
o	    DA0MS0	    o
seu	    DP3MSS	    seu
nome	NCMS000	    nome
?	    Fit	        ?

And so on for other supported languages.

Chunking

Suppose you want to tokenize, tag and annotate a German text with nominal and verbal chunks.

$ echo 'Das ist ein Test.' | docker run -i leodido/treetagger tagger-chunker-german

Outputs:

<NC>
Das	    PDS	    die
</NC>
<VC>
ist	    VAFIN	sein
</VC>
<NC>
ein	    ART	    eine
Test	NN	    Test
</NC>
.	    $.	    .
