The annotations are fine-grained, including aspects and subjective phrases.

The corpus consists of 622 English and 611 German reviews for coffee machines, cutlery, microwaves, toaster, trash cans, vacuum cleaner, washing machines and dishwasher. The English corpus is annotated with more than 8000 aspects and 5000 subjective phrases, the German part with more than 6000 aspects and around 5000 subjective phrases (depending on the annotator). Each review is independently annotated by two annotators.
