A Dataset of Polarities and Emotions from Brazilian Portuguese Play Store Reviews

User reviews play a crucial role in shaping consumer perceptions and guiding decision-making processes in the digital marketplace. With the rise of mobile applications, platforms like the Google Play Store serve as hubs for users to express their opinions and experiences with various apps and services. Understanding the polarities and emotions conveyed in these reviews provides valuable insights for developers, marketers, and researchers alike.

The dataset consists of user reviews collected from the "Trending" section of the Google Play Store in May 2023. A total of 300 reviews were gathered for each of the top 10 most downloaded applications during this period. Each review in the dataset has been meticulously labeled for polarity, categorizing sentiments as positive, negative, or neutral, and emotion, encompassing a range of emotional responses such as happiness, sadness, surprise, fear, disgust and anger.

Additionally, it's worth noting that this dataset underwent a rigorous annotation process. Three annotators independently classified the reviews for polarity and emotion. Afterward, they reconciled any discrepancies through discussion and arrived at a consensus for the final annotations. This ensures a high level of accuracy and reliability in the labeling process, providing researchers and practitioners with trustworthy data for analysis and decision-making.

It's important to highlight that all reviews in this dataset are in Brazilian Portuguese, reflecting the specific linguistic and cultural nuances of the Brazilian market. By leveraging this dataset, stakeholders gain access to a robust resource for exploring user sentiment and emotion within the context of popular mobile applications in Brazil.
