Abstract:
Aspect-Based Sentiment Analysis (ABSA) is a fine-grained approach to understanding sentiments by identifying specific aspects of an entity and the sentiments expressed towards them. This paper explores the application of deep learning techniques to ABSA, addressing the challenges of handling unstructured and ambiguous text from diverse domains such as social media, product reviews, and customer feedback. We propose a deep learning-based model utilizing the pre-trained Bidirectional Encoder Representations from Transformers (BERT) for ABSA tasks. Our methodology reformulates input sentences to explicitly highlight aspect terms and fine-tunes a bert-base-uncased model using labeled sentiment data. The input format is designed to integrate aspect-specific context by combining aspect terms with their corresponding review sentences, enabling the model to disambiguate sentiment in multi-aspect scenarios. The dataset is preprocessed and encoded using BERT’s tokenizer, and class labels are transformed using label encoding for multi-class classification. We train the model using the AdamW optimizer and monitor performance using categorical loss. Experimental results show that the proposed model achieves high accuracy in distinguishing positive, negative, and neutral sentiments at the aspect level.
