# ArkTS-CodeSearch: A Open-Source ArkTS Dataset for Code Retrieval
[Paper](https://huggingface.co/papers/2602.05550) | [Evaluation Code](https://github.com/hreyulog/retrieval_eval) | [Fine-Tuned Model](https://huggingface.co/hreyulog/embedinggemma_arkts)
This dataset collects **function-level information from ArkTS (HarmonyOS Ark TypeScript) projects**, including original functions, docstrings, abstract syntax tree (AST) representations, obfuscated versions, and source code metadata. It is suitable for tasks such as code analysis, code understanding, AST research, and code search.
ArkTS is a core programming language in the OpenHarmony ecosystem. This dataset was constructed from open-source repositories crawled from GitHub and Gitee, targeting code retrieval and code evaluation tasks.
Note: ⚠️ Not Enterprise-Ready: This dataset is designed for research only. Some of the collected code may come from repositories without an explicit open-source license. Users should be aware that usage of such code may be subject to copyright restrictions.
## Dataset Structure
The dataset contains three splits:
- `train`: Training set
- `validation`: Validation set
- `test`: Test set
Each split is a **JSON Lines (.jsonl) file**, where each line is a JSON object representing a single function.
## Features / Columns
| Field | Type | Description |
|-------|------|------------|
| `nwo` | string | Repository name |
| `sha` | string | Commit SHA |
| `path` | string | File path |
| `language` | string | Programming language |
| `identifier` | string | Function identifier / name |
| `docstring` | string | Function docstring |
| `function` | string | Original function source code |
| `ast_function` | string | AST representation of the function |
| `obf_function` | string | Obfuscated function source code |
| `url` | string | URL to the code in the repository |
| `function_sha` | string | Function-level SHA |
| `source` | string | Code source (GitHub / Gitee) |
## Usage
```python
from datasets import load_dataset
# Load the dataset
dataset = load_dataset("hreyulog/arkts-code-docstring")
# Inspect the first training example
print(dataset["train"][0])
# Check dataset features
print(dataset["train"].features)
```
