The Classical Language Toolkit (CLTK) offers natural language processing support for Classical languages. In some areas, it extends the NLTK. The goals of the CLTK are to:
- compile analysis-friendly corpora in a variety of Classical languages (currently available for Chinese, Coptic, Greek, Latin, Pali, and Tibetan);
- gather, improve, and generate linguistic data required for NLP (Greek and Latin are in progress, with more in the pipeline);
- develop a free and open platform for generating reproducible, scientific research that advances the study of the languages and literatures of the ancient world.
The docs are at docs.cltk.org.
CLTK supports Python version 3.4 and 3.5. The software only runs on POSIX–compliant operating systems (Linux, Mac OS X, FreeBSD, etc.).
$ pip install cltkSee docs for complete installation instructions.
The CLTK organization curates corpora which can download directly or, better, imported by the toolkit.
See the Quickstart for contributors for an overview of the process. If you're looking to start with a small contribution, see the Issue tracker for "easy" jobs needing to be done. Bigger projects may be found at Project ideas page. Of course, new ideas are always welcome.
Each major release of the CLTK is given a DOI, a type of unique identity for digital documents. This DOI ought to be included in your citation, as it will allow researchers to reproduce your results should the CLTK's API or codebase change. To find the CLTK's current DOI, observe the blue DOI button in the repository's home on GitHub. To the end of your bibliographic entry, append DOI plus the current identifier. You may also add version/release number, located in the pypi button at the project's GitHub repository homepage.
Thus, please cite core software as something like:
Kyle P. Johnson et al.. (2014-2016). CLTK: The Classical Language Toolkit. DOI 10.5281/zenodo.<current_release_id>
A style-neutral BibTeX entry would look like this:
