Corpus of Classical Tibetan

The Annotated Corpora of Classical Tibetan (ACTib) is a corpus containing 80 million words of Classical Tibetan has been available in Sketch Engine since spring 2017.

Corpus texts were taken from the e-text collection of the Buddhist Digital Resource Center. 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 morpho-syntactically annotation was processed by Memory-Based Tagger (Hill & Garrett 2017) trained on 300,000 words comprised of three distinct collections (Classical corpus, Saint Petersburg corpus, Tibetan catalogue of the Berlin State Library). See the Tibetan part-of-speech tagset.


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