CodeSwitch-Reddit corpus collection, pre-processing and analysis is described in the paper:
CodeSwitch-Reddit: Exploration of Written Multilingual Discourse in Online Discussion Forums, Rabinovich et al., 2019. Supplemental materials are in CodeSwitch-Reddit: Supplemental Materials.
The full dataset is available at https://www.cs.toronto.edu/~ella/code-switch.reddit.tar.gz. A cleaner monolingual part of the dataset was generated in Jan 2020, you may want to re-download if interested in that part of the corpus.
cs_main_reddit_corpus.csv: the main dataset comprising English-{Tagalog, Greek, Romanian, Indonesian, Russian} code-switched posts, detected with high accuracy (refer to the paper for details).
cs_additional_reddit_corpus.csv: additional dataset comprising English-{Spanish, Turkish, Arabic, Croatian, Albanian} code-switched posts. Despite its lower (true code-switching) accuracy, we recognize the potential usefulness of this additional data, and release it as an addendum to our main corpus, for possible further cleanup and preprocessing.
eng_monolingual_reddit_corpus.csv: monolingual English posts from the set of country-specific subreddits.
