# PharmaShip: An Entity-Centric, Reading-Order-Supervised Benchmark for Chinese Pharmaceutical Shipping Documents

### 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.
### Dataset Examples
PharmaShip contains scanned documents with complex tabular layouts, stamps, and handwritten text. We provide fine-grained annotations at the token, entity, and relation levels, as well as reading order supervision.

| **Reading Order Prediction (ROP)**<br>(DAG-based reading order based on relation extraction) | ![Reading Order</code></code></code></code>](pics/example/aonuo_segment_ro.jpg) |
### Dataset Statistics
PharmaShip consists of **161** annotated scanned documents with **11,295** segments. The dataset is officially split into 128 samples for training and 33 samples for validation.
Compared to existing datasets like FUNSD, CORD, and SROIE, PharmaShip features a higher density of entities and relations per sample, making it a more challenging benchmark for layout-intensive scenarios.

### Benchmark Results
We benchmarked five representative baselines: **LiLT** , **LayoutLMv3** , **GeoLayoutLM** , and their **RORE (Reading-Order-Relation Enhanced)** variants.
The experiments demonstrate that injecting reading-order-oriented regularization consistently improves performance on SER and Entity Linking (EL) tasks.
