corpy 0.2.3

Tools for processing language data.

Installation

$ pip3 install corpy

Only recent versions of Python 3 (3.6+) are supported by design.

What is CorPy?

A fancy plural for corpus ;) Also, a collection of handy but not especially mutually integrated tools for dealing with linguistic data. It abstracts away functionality which is often needed in practice for teaching and/or day to day work at the Czech National Corpus, without aspiring to be a fully featured or consistent NLP framework.

The short URL to the docs is: https://corpy.rtfd.io/

Here’s an idea of what you can do with CorPy:

• add linguistic annotation to raw textual data using either UDPipe or MorphoDiTa

Note

Should I pick UDPipe or MorphoDiTa?

UDPipe is the successor to MorphoDiTa, extending and improving upon the original codebase. It has more features at the cost of being somewhat more complex: it does both morphological tagging (including lemmatization) and syntactic parsing, and it handles a number of different input and output formats. You can also download pre-trained models for many different languages.

By contrast, MorphoDiTa only has pre-trained models for Czech and English, and only performs morphological tagging (including lemmatization). However, its output is more straightforward – it just splits your text into tokens and annotates them, whereas UDPipe can (depending on the model) introduce additional tokens necessary for a more explicit analysis, add multi-word tokens etc. This is because UDPipe is tailored to the type of linguistic analysis conducted within the UniversalDependencies project, using the CoNLL-U data format.

MorphoDiTa can also help you if you just want to tokenize text and don’t have a language model available.

• easily generate word clouds

• generate phonetic transcripts of Czech texts

• wrangle corpora in the vertical format devised originally for CWB, used also by (No)SketchEngine

• plus some command line utilities

Development

Dependencies and building the docs

The canonical dependency requirements are listed in pyproject.toml and frozen in poetry.lock. However, in order to use autodoc to build the API docs, the package has to be installed, and corpy has dependencies that are too resource-intensive to build on ReadTheDocs.

The solution is to use a dummy setup.py which lists only the dependencies needed to build the docs properly, and mock all other dependencies by listing them in autodoc_mock_imports in docs/conf.py. This dummy setup.py is used to install corpy only on ReadTheDocs (via the appropriate config option in .readthedocs.yml). The same goes for the MANIFEST.in file, which duplicates the tool.poetry.include entries in pyproject.toml for the sole benefit of ReadTheDocs.
