Opis:
Covid-19 has spread across the world and many different vaccines have been developed to counter its surge. To identify the correct sentiments associated with the vaccines from social media posts, we fine-tune various state-of-the-art pretrained transformer models on tweets associated with Covid-19 vaccines. Specifically, we use the recently introduced state-of-the-art RoBERTa, XLNet, and BERT pre-trained transformer models, and the domain-specific CT-BER and BERTweet transformer models that have been pre-trained on Covid-19 tweets. We further explore the option of text augmentation by oversampling using the language model-based oversampling technique (LMOTE) to improve the accuracies of these models - specifically, for small sample data sets where there is an imbalanced class distribution among the positive, negative and neutral sentiment classes. Our results summarize our findings on the suitability of text oversampling for imbalanced, small-sample data sets that are used to fine-tune state-of-the-art pre-trained transformer models as well as the utility of domain-specific transformer models for the classification task.

Opis:
The paper aims to present different ways of showing religious and quasi-religious attitudes in contemporary Polish documentaries. The discussion is based on four feature-length films: Kites by Beata Dzianowicz (2008), Communion by Anna Zamecka (2016), Who Will Write Our History by Roberta Grossman (2018), and Tell No One by Tomasz Sekielski (2019). The author evaluates the methodological usefulness of reflection in the documentary of the “religious film” category used in Polish research and the concept of “transcendent(al) style” taken from Paul Schrader’s book. Occasionally touching upon the question of the relationship with audiences, the author also mentions the paradigm of Polish Romanticism present in contemporary culture.
