+# Disputability Datasets for Taiwanese Administrative Tax Cases (DDTAT)
+
+## Overview
+This dataset contains over 50,000 administrative litigation judgments from Taiwan, primarily focusing on tax law cases. It provides a rich resource for legal natural language processing (LegalNLP), specifically for tasks such as disputability detection, legal judgment prediction, and document structure analysis.
+
+The dataset is hosted on Hugging Face Hub: [hochienH/DDTAT](https://huggingface.co/datasets/hochienH/DDTAT)
+
+The dataset is organized into two configurations:
+1.  **judgements**: Full text and metadata for each judgment.
+2.  **sentences**: Over 4.5 million sentences annotated with disputability labels.
+
+## Dataset Structure
+
+### 1. Judgements (Config: `judgements`)
+*   **Content**: Full text and metadata of judgments.
+*   **Fields**:
+    *   `JID`: Unique Judgment ID (e.g., `KSBA,102,訴,424,20150325,3`)
+    *   `JYEAR`: Case Year
+    *   `JCASE`: Case Type (e.g., 訴, 簡)
+    *   `JNO`: Case Number
+    *   `JDATE`: Judgment Date
+    *   `JTITLE`: Case Reason/Title (e.g., 綜合所得稅)
+    *   `JFULL`: Full text of the judgment
+    *   `DISPUTABILITY`: Document-level label
+
+### 2. Sentences (Config: `sentences`)
+*   **Content**: Annotated sentences.
+*   **Fields**:
+    *   `檔名`: Corresponding Judgment ID
+    *   `句子編號`: Sentence Sequence ID
+    *   `句子內容`: Text content of the sentence
+    *   `DISPUTABILITY`: Sentence-level label
+
+## Usage
+
+You can easily load the dataset using the Hugging Face `datasets` library.
+
+```python
+from datasets import load_dataset
+
+# Load Sentences
+ds_sentences = load_dataset("hochienH/DDTAT", "sentences")
+print(ds_sentences['train'][0])
+
+# Load Judgments
+ds_judgements = load_dataset("hochienH/DDTAT", "judgements")
+print(ds_judgements['train'][0])
+```
+
+## Statistics
+
+### Data Volume
+*   **Total Judgments**: 52,993
+*   **Total Sentences**: 4,479,889
+
+### Length Distribution (Characters)
+| Level | Mean | Median | Std Dev | Q1 (25%) | Q3 (75%) |
+|-------|------|--------|---------|----------|----------|
+| **Sentence** | 101.09 | 76.00 | 92.36 | 42.00 | 132.00 |
+| **Judgment** | 11,487.13 | 9,207.00 | 8,257.11 | N/A | N/A |
