Definition

Aspect-based sentiment analysis is a technique used in natural language processing that focuses on determining the sentiment associated with specific aspects or features of an entity, rather than assessing the overall sentiment. This method allows for a more granular understanding of opinions, providing insights into what users feel about particular elements of products, services, or experiences.
