+# HyperAlign-Bench
+
+This repository contains the released **HyperAlign-Bench** data bundle for the paper **Hypergraph as Language**.
+
+HyperAlign-Bench is a benchmark for evaluating high-order association modeling in hypergraph-language alignment. It provides vertex classification and hyperedge classification tasks under the same question-answering protocol used by **Hyper-Align**.
+
+The released bundle includes processed hypergraph tensors, task samples, prebaked samples, Qwen3-Embedding-0.6B features, and overview features for five datasets.

+
+Each dataset directory follows this structure:
+
+```text
+processed_data.pt
+meta.json
+samples/
+embeddings/qwen3emb_0.6b/
+overview/qwen3emb_0.6b/
+```
+
+- `processed_data.pt` contains the processed hypergraph data.
+- `meta.json` contains dataset metadata.
+- `samples/` contains the VC and HEC task samples.
+- `embeddings/qwen3emb_0.6b/` contains node and hyperedge text features.
+- `overview/qwen3emb_0.6b/` contains overview features used by the released Hyper-Align pipeline.
