Item Análise de sentimentos em reviews de jogos digitais da Plataforma Steam(2024-09-26) Albuquerque, Júlia de Melo; Albuquerque Júnior, Gabriel Alves de; http://lattes.cnpq.br/1399502815770584Sentiment analysis is an area that investigates the emotional expressions of human language, aiming to understand the underlying needs and opinions expressed in texts. Its complexity lies in the ability to discern not only the textual content but also the implicit emotional matrices. With technological advancements, the ease of publicly expressing opinions is disseminated through various means, with online gaming being a sector that attracts numerous player posts about various available titles. However, this diversity of audiences and topics makes it challenging to understand the expressed sentiment that pervades this universe. The aim of this study is to apply sentiment analysis techniques to digital game reviews, adopting an approach focused on supervised machine learning algorithms and pre-polarized libraries, in order to identify the best classification path capable of discerning the sentiments expressed by users in the reviews. This operation considers an approach with all opinions and another focused on each game’s specific genre. This analysis was conducted by exploring data from an online game distribution company (Steam), followed by data preparation due to the peculiarities present in the records. The results reveal that machine learning models outperform traditional approaches, such as using the VADER library, showing a higher precision by approximately 10% in captures. A difference of 20% more was observed in metrics such as recall and F1-score. This study represents an analytical contribution to the field of sentiment analysis, highlighting the model’s ability to deal with the complexity of human language.Item Implementação de um sistema mobile colaborativo para acompanhamento do quadro de pacientes com esclerose múltipla por meio de análise de sentimento(2024-10-02) Araujo, Paula Priscila da Cruz; Gouveia, Roberta Macêdo Marques; Tschá, Elizabeth Regina; http://lattes.cnpq.br/9598413463162759; http://lattes.cnpq.br/2024317361355224; http://lattes.cnpq.br/0280090820230057The study aims to develop a mobile system to facilitate the monitoring of patients with Multiple Sclerosis (MS), based on the Human-Centered Design (HCD) Toolkit to meet patient needs. The app allows patients to record and track emotions, symptoms, and treatments, offering monthly reports and personalized alerts. For sentiment analysis, the machine learning algorithms XGBoost and Naive Bayes were used, with XGBoost showing better performance, achieving 87.56% accuracy and an F1-Score of 0.876, while Naive Bayes obtained 62.25% accuracy and an F1-Score of 0.524. The results indicate the tool’s effectiveness in emotional and medical monitoring, contributing to an improved quality of life.
