+# Ring-lite-rl-data
+
+This dataset is a curated subset of high-quality problems across mathematics and code domains designed for reinforcement learning in the [Ring-lite](https://huggingface.co/inclusionAI/Ring-lite) model. This dataset contains:
+
+* **Mathematics**: Over 39,000 rigorously curated problems sourced from:
+    - Open-source datasets (BigMath, DeepScaleR, DAPO, DeepMath-103K)
+    - Art of Problem Solving (AoPS) contest collections
+* **Code**: Approximately 8,400 verified coding problems from:
+    - Programming competition resources (CodeContest, TACO, APPS)
+    - QOJ online judge platform
+    - All problems include validated "Accepted" solutions and test cases
+
+## Dataset Construction
+
+### Data Sources
+- **Mathematics**: Problems collected from open-source datasets, filtered through strict quality control
+- **Code**: Problems from open-source programming competition resources with verified solutions
+
+### Curation Pipeline
+Our data undergoes a rigorous three-stage curation process:
+
+1. **Data Cleansing**:
+   - Removal of problems with invalid characters, images, or multiple subquestions
+   - Strict character-based and semantic-based deduplication
+   - Exclusion of easily guessable problems (multiple-choice, True/False questions)
+
+2. **Answer Verification**:
+   - LLM-based verification using models of different sizes
+   - Human expert annotation
+   - Problems failing verification are excluded
+
+3. **Data Annotation**:
+   - Multi-dimensional labeling (source, educational level, domain knowledge)
+   - Mathematical Subject Classification (MSC) for math problems
+   - Model-aware difficulty assessment
+
+## Dataset Fields

+
+### Mathematics
+- **context**: The problem statement
+- **groundtruth**: Verified correct answer
+- **type**: Problem category
