Abstract: Abstract In the era of rapid internet expansion, social networking platforms have become indispensable channels for individuals to convey their emotions and opinions to a global audience. People employ various media types, including text, images, audio, and video, to articulate their sentiments. However, the sheer volume of textual content on web-based social media platforms can be overwhelming. These platforms generate an enormous amount of unstructured data every second. To gain insights into human psychology, it is imperative to process this data as quickly as it is produced. This can be achieved through sentiment analysis, an advanced technique called Transformer-based model (TBM) which discerns the polarity of text, determining whether the author holds a positive, negative, or neutral stance towards a subject, service, individual, or location. The performance of this model can vary based on factors like the dataset used, the specific Transformer variant, model hyper parameters, and the evaluation metrics employed. Findings from this study show that social media users with depression or anorexia may be identified by the presence and unpredictability of their emotions. The proposed model is used to analyze text data and make sentiment predictions effectively. The proposed TBM strategy illustrated predominant execution over distinctive measurements compared to other methods. For 50 clients, TBM accomplished an precision of 94.23%, accuracy of 89.13%, and review of 91.59%. As the client check expanded to 100, 150, 200, and 250, TBM reliably outflanked others, coming to up to 97.03% precision, 92.89% exactness, and 93.51% review. These comes about emphasize the viability of the TBM approach over elective strategies.
