+# OATS Dataset
+
+## Description
+
+The OATS (Opinion Aspect Target Sentiment) dataset is a comprehensive collection designed for the Aspect Sentiment Quad Prediction (ASQP) or Aspect-Category-Opinion-Sentiment (ACOS) task. This dataset aims to facilitate research in aspect-based sentiment analysis by providing detailed opinion quadruples extracted from review texts. Additionally, for each review, we offer tuples summarizing the dominant sentiment polarity toward each aspect category discussed.
+
+The dataset covers three distinct domains: Amazon FineFood reviews, Coursera course reviews, and TripAdvisor Hotel reviews, offering a broad spectrum for analysis across different types of services and products.
+Structure
+
+The dataset is structured into two primary components:
+
+    Opinion Quadruples: Detailed annotations on the level of individual opinions, including the aspect, the sentiment target, and the corresponding sentiment.
+    Review-Level Tuples: Aggregate information at the review level, indicating the overall sentiment polarity for each aspect category mentioned.
+
+## Domains
+
+    Amazon FineFood Reviews
+    Coursera Course Reviews
+    TripAdvisor Hotel Reviews
+
+Each domain is annotated from scratch, ensuring high-quality data for nuanced sentiment analysis tasks.
