	### Dataset Summary

	The PolEmo2.0 is a set of online reviews from medicine and hotels domains. The task is to predict the sentiment of a review. There are two separate test sets, to allow for in-domain (medicine and hotels) as well as out-of-domain (products and university) validation.

	### Supported Tasks and Leaderboards

	[More Information Needed]

	### Languages

	Polish

	## Dataset Structure

	### Data Instances

	[More Information Needed]

	### Data Fields

	- sentence: string, the review
	- target: sentiment of the sentence class

	The same tag system is used in plWordNet Emo for lexical units: [+m] (strong positive), [+s] (weak positive), [-m] (strong negative), [-s] (weak negative), [amb] (ambiguous) and [0] (neutral).

	Note that the test set doesn't have targets so -1 is used instead
