| # LineEX | |
| This dataset repo contains: | |
| - the uploaded `train` split with `397,993` images | |
| - the released `test` split with `20,000` images | |
| - Repo: `13point5/line-ex` | |
| ## Shared Schema | |
| - `image_id` | |
| - `file_name` | |
| - `image` | |
| - `width` | |
| - `height` | |
| - `data_type` | |
| - `chart_elements` | |
| - `lines` | |
| ## `chart_elements` fields | |
| - `annotation_id` | |
| - `category_id` | |
| - `category_name` | |
| - `bbox_xywh` | |
| - `area` | |
| - `text` | |
| - `line_id` | |
| ## `lines` fields | |
| - `annotation_id` | |
| - `category_id` | |
| - `category_name` | |
| - `line_name` | |
| - `polyline_xy` | |
| - `raw_series_xy` | |
| - `area` | |
| ## Notes | |
| - The repo uses a shared nested schema across splits. | |
| - The `train` split is streamed directly from `train.zip` and uploaded as parquet shards to | |
| reduce local disk usage. | |
| - The `test` split uses the 10-class chart-element mapping defined in the LineEX codebase. | |
| - The `train` split uses a different chart-element label vocabulary, but the HF feature shape | |
| is identical. | |
| - `lines.line_name` is derived from legend structure and may be `null` when the legend-text | |
| association is ambiguous. | |
