	`wisesight1000` contains Thai social media texts randomly drawn from the full `wisesight-sentiment`, tokenized by human annotators.
	Out of the labels `neg` (negative), `neu` (neutral), `pos` (positive), `q` (question), 250 samples each. Some texts are removed because
	they look like spam.Because these samples are representative of real world content, we believe having these annotaed samples will allow
	the community to robustly evaluate tokenization algorithms.
