The TCOPE dataset consists of public tweets (amounting to about 13.5 million words) collected from 13 major cities from the Philippines.
Tweets are either purely in English or involve code-switching between English and Filipino.
Tweets are tagged for part-of-speech and dependency parsing using spaCy. Tweets collected are from 2010 to 2021.
The publicly available dataset is only a random sample (10%) from the whole TCOPE dataset, which consist of roughly 27 million tweets
(amounting to about 135 million words) collected from 29 major cities during the same date range.
