pip install typecraft_python

Features

  • Parsing of the Typecraft XML format.
  • Manipulation of the Typecraft IGT model format.
    • Integrating with NLTK
    • Integrating with TreeTagger
  • Provides a CLI that can be used to load, convert and manipulate raw text and Typecraft XML files.

Usage

Usage: tpy [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  convert
  ntexts   This command lists the number of texts in a...
  raw
  xml

Credits

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.

Installation

Stable release

To install Typecraft XML Python, run this command in your terminal:

$ pip install typecraft_python

This is the preferred method to install Typecraft XML Python, as it will always install the most recent stable release.

If you don’t have pip installed, this Python installation guide can guide you through the process.

From sources

The sources for Typecraft XML Python can be downloaded from the Github repo.

You can either clone the public repository:

$ git clone git://github.com/Typecraft/tc_xml_python

Or download the tarball:

$ curl  -OL https://github.com/Typecraft/tc_xml_python/tarball/master

Once you have a copy of the source, you can install it with:

$ python setup.py install

Usage

The system can be used in two ways: As a CLI, and as a library.

CLI

The CLI currently has 4 active commands:

  • raw
  • xml
  • ntexts
  • par

raw loads raw texts, and performs a number of operations on it. It will always convert the result to a TC-XML file. xml loads TC-xml files, and performs a number of operations on it. ntexts loads TC-xml files, and reports how many text-objects exist in the file. par parses parallel corpora.

All file inputs in the commands accepts “-” as input, which specifies that the input should be read from stdin. The examples in Combined examples gives some examples of this.

raw

The raw command always loads raw text, and always outputs TC-XML files.

Usage: tpy raw [OPTIONS] [INPUT]...

Options:
  --sent-tokenize / --no-sent-tokenize
                                  Will sentence tokenize if true.
  --tokenize / --no-tokenize      Will tokenize if true.
  --tag / --no-tag                Will tag if true.
  --tagger TEXT                   The tagger to use.
  --title TEXT                    Title to attach to generated texts.
  --language TEXT                 The language of the input text(s).
  --meta <TEXT TEXT>...           Metadata to attach to generated text(s)
  --tagset TEXT                   If set, the tags in the output will be
                                  converted into this tagset.
  -o, --output PATH               If given, the output will be written to this
                                  file, instead of stdout.
  --help                          Show this message and exit.

By default, the command will perform

  • Sentence-tokenization
  • Tokenization
  • Tagging using NLTK
  • All the above assuming the language is English.
Examples

Load a raw file, tokenize and tag it, and output xml (to stdout):

$ tpy raw your_file.txt

To save to a file

$ tpy raw your_file.txt -o output.xml
# or
$ tpy raw your_file.txt > output.xml

To tag using a specific tagger:

$ tpy raw your_file.txt --tagger=tree  # Tags using the tree tagger

Attach “Annotator” metadata:

$ tpy raw your_file.txt --meta Annotator "Tormod Haugland"

Tags a german text

$ tpy raw your_file.txt --language=de

Tags a german text using the TreeTagger and converts all tags to the Typecraft tagset:

$ tpy raw your_file.txt --tagger=tree --tagset=tc --language=de

Suppose you have the file input.txt with the following contents:

Ich bin glucklich.

You now run the command

$ tpy raw input.txt --tagger=tree --language=de --tagset=tc

Your output (after prettifying) will be:

<?xml version="1.0" encoding="UTF-8"?>

            <morpheme baseform="." meaning="" text="." />
         </word>
      </phrase>
   </text>
</typecraft>

xml

The xml command loads a TC-XML file, and performs a number of specified operations on it.

Usage: tpy xml [OPTIONS] [INPUT]...

Options:
  --tokenize / --no-tokenize  Will re-tokenize all phrases if true.
  --tag / --no-tag            Will tag if true.
  --tagger TEXT               The tagger to use.
  --split INTEGER             If greater than 1, the output will be split into
                              the given value number of texts.
  --merge / --no-merge        If true, will merge all files.
  --title TEXT                Title to attach to generated texts.
  --override-language TEXT    If set, will override the language used in all
                              calculations and set the language for all texts.
  --meta <TEXT TEXT>...       Metadata to attach to generated text(s)
  --tagset TEXT               If set, the tags in the output will be converted
                              into this tagset.
  -o, --output PATH           If given, the output will be written to this
                              file, instead of stdout.
  --help                      Show this message and exit.

By default the command will do nothing but re-output the input. The “-o” flag behaves identically to the one in raw.

Notes
  • Split will split into the given number of files, even if the given number is larger than the number of phrases.
Examples

Load a text and splits it into 10 smaller texts (all contained in one file):

$ tpy xml your_file.xml --split 10

Load a text and convert the tagset:

$ tpy xml your_file.xml --tagset=tc

Tag or re-tag a text:

$ tpy xml your_file.xml --tag --tagger=tree

Change language and set some metadata:

$ tpy xml --override-language=nob \
    --meta Annotator "Tormod Haugland" \
    --meta "Content description" "This is some cool content"

par

par will parse parallel corpora files. Currently there is only one supported format, named continuous or linear. The output is always Typecraft XML. This format requires there to to be n consecutive lines in the file, one per language, for each phrase that is to be translated.

Note that the Typecraft XML format only supports two translation tiers.

Usage: tpy par [OPTIONS] [INPUT]...                                                                                                    │

  The `par` command attempts to parse raw text as parallel corpora.                                                                    │

  The input is one or more files containing raw text, in some parallel                                                                 │
  format.                                                                                                                              │

Options:                                                                                                                               │
  -f, --format TEXT        The format of the parallel file.                                                                            │
  -n, --num-langs INTEGER  The number of languages present.                                                                            │
  -o, --output PATH        If given, the output will be written to this file,                                                          │
                           instead of stdout.                                                                                          │
  --help                   Show this message and exit.
Examples

Given the file input.txt with the contents below:

Hi this is a nice sentence.
Hei dette er en fin setning.
This is sentence number two.
Dette er setning nummber to.

Which is a parallel corpus file with two languages (Norwegian and English). We can call the command

$ tpy par -n 2 input.txt

The resulting output will be Typecraft XML with a single text with two phrases. The phrases will not be tokenized, with the appropriate amount of free translations tiers set.

ntexts

ntexts will output the number of texts in a TC-XML file.

Examples
Usage: tpy ntexts [OPTIONS] INPUT

  This command lists the number of texts in a TCXml file. :param input:
  :return:

Options:
  --help  Show this message and exit.
Examples
$ tpy ntexts input_with_10_texts.xml
10

Combined examples

Load and treat a raw file, then split it into 10 texts:

# The "-" in the xml command reads the piped input
$ tpy raw input.txt | tpy xml - --split 10

Load and treat a raw file, then merge it with an existing files texts.

$ tpy raw append_this.txt | tpy xml - to_this.xml --merge

Make sure ntexts behaves correctly:

$ tpy raw input.txt | tpy xml - --split 50 | tpy ntexts -
100

Merge files then re-split:

$ tpy xml corpus{1..100}.xml --merge | tpy xml - -split 1000
