+Sentiment analysis model that uses the Roberta sentiment tweet pre-trained model (from https://huggingface.co/cardiffnlp/twitter-roberta-base-sentiment), and fine-tuned on a dataset containing Trip Advisor reviews (from https://www.kaggle.com/datasets/arnabchaki/tripadvisor-reviews-2023).
+
+Reviews with 1 or 2 stars are considered 'Negative', 3 stars are 'Neutral', and 4 or 5 stars are 'Positive'.
+
+Should be loaded with the following code:
+
+```
+# Load pre-trained model and tokenizer
+model_name = "gosorio/robertaSentimentFT_TripAdvisor"
+tokenizer_name = "cardiffnlp/twitter-roberta-base-sentiment"
+device = torch.device('cuda') if torch.cuda.is_available() else torch.device('cpu')
+
+tokenizer = AutoTokenizer.from_pretrained(tokenizer_name)
+model = AutoModelForSequenceClassification.from_pretrained(model_name, num_labels=3).to(device)
+```
