-# Dataset Card for "IBEM-v1-cropped"
+# IBEM Cropped: Bounding Box Mathematical Expressions from Scientific Pages
 
-[More Information needed](https://github.com/huggingface/datasets/blob/main/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)
+A processed version of the **IBEM Dataset** (Anitei et al., 2023), designed for the training and evaluation of image-to-markup models, expression recognition, and related document understanding tasks. Each sample in this dataset consists of a cropped image region containing a **single mathematical expression** (either displayed or embedded), along with its corresponding LaTeX annotations.
+
+## Dataset Summary
+
+This dataset is derived from the original **IBEM dataset** by extracting individual mathematical expressions using the provided bounding boxes, and cropping them from their original document pages. All page-level coordinates were specified as percentages and converted to absolute pixel coordinates during cropping.
+
+Each record includes:
+- A cropped image of the mathematical expression.
+- The original LaTeX string (`latex`).
+- A normalized LaTeX string (`latex_norm`) with visual formatting removed.
+- The ID of the original page.
+- The expression type (`isolated` or `embedded`).
+
+## Dataset Structure
+
+**Features:**
+
+```python
+features = Features({
+    "image": Image(),
+    "latex": Value("string"),
+    "latex_norm": Value("string"),
+    "page_id": Value("string"),
+    "expr_type": Value("string"),
+})
+````
+
+**Splits:**
+
+The dataset is split into standard `train`, `val`, and `test` subsets based on the official partition lists provided by the authors (`Tr*.lst`, `Va*.lst`, `Ts*.lst`).

+
+## Original Dataset Description
+
+The IBEM dataset consists of 600 LaTeX documents with a total of 8,272 pages, containing:
+
+* **29,603 displayed mathematical expressions**
+* **137,089 embedded mathematical expressions**
+
+These were extracted from the LaTeX source files of documents in the **KDD Cup Collection**. The dataset supports a variety of tasks, including:
+
+* Mathematical expression detection and extraction
+* LaTeX recognition from printed page images
+* Indexing and search of STEM content in large-scale document archives
+
+## Preprocessing Notes
+
+* **Preamble fields** containing LaTeX macros were excluded.
+* All expressions were **cropped** to their respective bounding boxes and stored as image snippets.
+* Only the `latex` and `latex_norm` fields were retained for expression text.
+* Expressions split across multiple lines were treated as-is, using the duplicated complete LaTeX string provided by the original dataset.
