+# STS-Hard Dataset
+
+The STS-Hard dataset is a paraphrase detection test set derived from the STSBenchmark dataset. It was introduced as part of the **PARAPHRASUS: A Comprehensive Benchmark for Evaluating Paraphrase Detection Models**, presented at **COLING 2025**. The test includes the paraphrase label as well as individual annotation labels from two annotators:
+
+- **P1**: The semanticist.
+- **P2**: A student annotator.
+
+For more details, refer to the [original paper](https://arxiv.org/abs/2409.12060) that was presented at COLING 2025.
