# Dataset overview

This dataset identifies whether a GitHub repository description pertains to Japanese natural language processing (NLP).
The labels are categorized as **"Relevant (1)" and "Not Relevant (0)"**.

Problem Setting:
- Training Data: Repository descriptions from before 2022
- Test Data: Repository descriptions from 2023
- Objective: To detect repositories related to Japanese NLP

Data Collection:
- Positive Examples: Repositories listed in "[awesome-japanese-nlp-resources](https://github.com/taishi-i/awesome-japanese-nlp-resources)" as of September 9, 2023
- Negative Examples: Collected from the GitHub API and visually confirmed
- Note: The annotation process is subjective

Dataset Features:
- Subjective labeling
- Mixed English and Japanese descriptions
- Imbalanced label distribution

**These dataset features mirror real-world challenges and are ideal for evaluating models.**
Based on GitHub's terms of service, please use this dataset for research purposes only.


# How to use this dataset

How to load in Python.

```python
from datasets import load_dataset

dataset = load_dataset("taishi-i/awesome-japanese-nlp-classification-dataset")
```

Details of the dataset.

```python
DatasetDict({
    train: Dataset({
        features: ['label', 'text', 'url', 'created_at'],
        num_rows: 5496
    })
    validation: Dataset({
        features: ['label', 'text', 'url', 'created_at'],
        num_rows: 400
    })

        num_rows: 856
    })
})
```

# Baseline

Baseline trained with [bert-base-multilingual-cased](https://huggingface.co/bert-base-multilingual-cased).
Please use the baseline model from [here](https://huggingface.co/taishi-i/awesome-japanese-nlp-classification-model).
The F1-score for label 1 is important for this task.
