资源简介：
This dataset is generated syhthetically to create tables with following characteristics:
1. Empty cell percentage in following range [40,70] (Sparse)
2. There is clear seperator between rows and columns (Structured).
3. 15 <= num rows <= 30, 7 <= num columns <= 15 (Long)
### Load the dataset
```python
import io
import pandas as pd
from PIL import Image
def bytes_to_image(self, image_bytes: bytes):
return Image.open(io.BytesIO(image_bytes))
def parse_annotations(self, annotations: str) -> pd.DataFrame:
return pd.read_json(StringIO(annotations), orient="records")
test_data = load_dataset('nanonets/long_sparse_structured_table', split='test')
data_point = test_data[0]
image, gt_table = (
bytes_to_image(data_point["images"]),
parse_annotations(data_point["annotation"]),
)
```
本数据集为合成生成数据集，旨在构建具备如下特征的表格：
1. 空单元格占比处于区间[40,70]内（稀疏型（Sparse）表格）
2. 行列间具备清晰分隔符（结构化（Structured）表格）
3. 行数范围为15 ≤ 行数 ≤ 30，列数范围为7 ≤ 列数 ≤ 15（长型（Long）表格）
### 数据集加载
python
import io
import pandas as pd
from PIL import Image
def bytes_to_image(self, image_bytes: bytes):
return Image.open(io.BytesIO(image_bytes))
def parse_annotations(self, annotations: str) -> pd.DataFrame:
return pd.read_json(StringIO(annotations), orient="records")
test_data = load_dataset('nanonets/long_sparse_structured_table', split='test')
data_point = test_data[0]
image, gt_table = (
bytes_to_image(data_point["images"]),
parse_annotations(data_point["annotation"]),
)
