Mangalam Corpus of Buddhist Sanskrit Literature

This is a corpus of Buddhist Sanskrit Literature developed at the Mangalam Research Center (Berkeley, California) for the study of Buddhist Sanskrit lexicology. It comprises: 368 lemmatized and metadata-enriched Buddhist Sanskrit texts for a total of ~ 7 million words. a tokenised reference corpus of general Sanskrit including 267 texts for a total of ~ 13 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 for questions and feedback, please contact Ligeia Lugli, project director: ligeia.lugli@kcl.ac.uk Lemmatization notes The corpora are in romanised Sanskrit (UTF-8 encoding). Where multiple spelling variants involving a nasals are attested, we have normalised the spelling to ṃ. 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 & Limitations We are grateful to have received an Ashoka grant from the Khyentse Foundation to proofread samples of the Buddhist Sanskrit Corpus. Still, only 1.6% 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 ~90% (0.914 accuracy and 0.901 F1 score) Acknowledgments The 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. Changelog version 2.0 changes the title of the corpus, adds more Buddhist texts and improves pre-processing accuracy. version 1.9 adds more Buddhist texts, has better segmentation and lemmatization and is partially proofread version 1.8 adds more Buddhist texts and is partially proofread version 1.7 adds more Buddhist texts and a new pre-processed corpus of general Sanskrit version 1.6 adds more Buddhist texts, improves segmentation and adds an initial iteration of the lemmatised corpus version 1.5 adds more Buddhist texts, removes the reference corpus and improves segmentation version 1.4 adds 59 Buddhist texts and fixes some recurrent segmentation errors version 1.4.1 corrects some spacing and sentence parsing errorsThis corpus is being proofread thanks to funding from the Khyentse Foundatio
