description: This is a Sanskrit corpus developed at the Mangalam Research Center (Berkeley, California) for the study of Buddhist Sanskrit lexicology.

It comprises:



 446 lemmatized and metadata-enriched Buddhist Sanskrit texts for a total of ~ 7.5 million words. 

a lemmatized reference corpus of general Sanskrit including 375 texts for a total of ~ 15 million words

a metadata table with information about each text in the Buddhist and Reference corpora

stemmed and normalised version of the Buddhist corpus & sketch grammar for use in Sketch Engine


Lemmatization notes

The corpora are in romanised Sanskrit (UTF-8 encoding). Verbs are lemmatized to the stem of the present indicative of third person singular; the verb root can be found in the Root column. We have replaced avagraha with a.

Data Quality & LimitationsWe are grateful to have received an Ashoka grant from the Khyentse Foundation to proofread samples of the Buddhist Sanskrit Corpus. Still, only a small percentage of the corpus has been proofread and many segmentation and lemmatization errors are likely to remain. Quantitative evaluation based on ~9000 proofread sentences puts pre-processing accuracy at ~94% (F1 0.938 averaged across all sentences).

AcknowledgmentsThe corpus had been first realised as part of the project 'Lexis and Tradition: variation in the vocabulary of Sanskrit Mahāyāna literature'. This project was funded by the British Academy through a Newton International Fellowship (NF161436) and hosted at the Department of Theology and Religious Studies at King's College London under the supervision of Prof. Henrietta Kate Crosby. It has subsequently been expanded and its accuracy improved with funding from the Khyentse Foundation (Ashoka Grant 2021-2022).

Dr. Bruno Galasek-Hul has contributed to versions 1.4 - 1.7 thanks to funding from the Mangalam Research Center for Buddhist Languages.

Dr Anuja Ajotikar, Madhusudan Rimal & Jai Paranjape have proofread sentences sampled from versions 1.7 to 2.0, thanks to funding from the Khyentse Foundation.

The reference corpus of general Sanskrit has been tokenised by Matej Martinc within the project 'Computing the Dharma' funded by the National Endowment for the Humanities (HAA-277246-21).

Thanks to GRETIL, CTS e-texts, Vinita Tseng, Jowita Kramer and Prof. Steinkellner for kindly giving their permission to include automatically processed versions of some of their editions in this corpus.
