In this article, we present a novel multidomain dataset of Polish text reviews, annotated with sentiment on different levels: sentences and the whole documents.The annotation was made by linguists in a 2+1 scheme (with inter-annotator agreement analysis).We present a preliminary approach to the classification of labelled data using logistic regression, bidirectional long short-term memory recurrent neural networks (BiLSTM) and bidirectional encoder representations from transformers (BERT).
