Researchers have developed ACAT, a novel web-based platform designed to streamline the annotation process for Aspect-Based Sentiment Analysis (ABSA) datasets. ACAT natively supports four distinct ABSA workflows, including aspect-category sentiment analysis and aspect sentiment triplet extraction. A key innovation is its automated ETL pipeline, which consolidates collaborative annotations and calculates Inter-Annotator Agreement (IAA) metrics upon export, producing ready-to-use training datasets. Preliminary testing showed ACAT significantly reduced annotation time and yielded high IAA scores. AI
