+# PharmaShip: An Entity-Centric, Reading-Order-Supervised Benchmark for Chinese Pharmaceutical Shipping Documents
+
+🔗 **Paper:** [https://arxiv.org/abs/2512.23714](https://arxiv.org/abs/2512.23714)
+
+### Description
+
+**PharmaShip** is a real-world Chinese dataset of scanned pharmaceutical shipping documents designed to stress-test pre-trained text-layout models under noisy OCR and heterogeneous templates.
+
+It covers three complementary tasks:
+
+* **Sequence Entity Recognition (SER)**
+* **Relation Extraction (RE)**
+* **Reading Order Prediction (ROP)**
+
+PharmaShip adopts an **entity-centric** evaluation protocol to minimize confounds across architectures and incorporates a directed acyclic reading order graph to capture layout-induced reading strategies.
