Corpus of Classical Tibetan

The Annotated Corpora of Classical Tibetan (ACTib) is a corpus containing 170 million words of Classical Tibetan. Version 2.0 has been available in Sketch Engine since November 2020.

Corpus texts were taken from the e-text collection compiled by the Buddhist Digital Resource Center (Zenodo: The ACTib corpus was lemmatized and part-of-speech tagged. There was also prepared a word sketch grammar for the Tibetan language enables users to explore the grammatical and collocational behavior of Tibetan words.

The corpus was built as part of the Tibetan in Digital Communication project. More information about the project and the author’s contacts can be found on the project page.

Part-of-speech tagging

The corpus was lemmatized and tagged using the TreeTagger tool by Helmut Schmid. The TreeTagger model was trained by Yeshe Tenley – parameter file and training corpus are to be found here. The lexicon, corpus, and enumeration of tags in the training data come from Dr. Nathan Hill.


The corpus is accessible to all users including trial users in Sketch Engine or can be downloaded in its entirety from Zenodo.
