# Kimbundu Sentiment Corpus

## Dataset Description

This dataset contains sentiment-labeled text data in Kimbundu for binary sentiment classification (Positive/Negative). Sentiments are extracted and processed from the English meanings of the sentences using DistilBERT for sentiment classification. The dataset is part of a larger collection of African language sentiment analysis resources.

## Dataset Statistics

- **Total samples**: 56,896
- **Positive sentiment**: 31789 (55.9%)
- **Negative sentiment**: 25107 (44.1%)

## Dataset Structure

### Data Fields

- **Text Column**: Contains the original text in Kimbundu
- **sentiment**: Sentiment label (Positive or Negative only)

### Data Splits

This dataset contains a single split with all the processed data.

## Data Processing

The sentiment labels were generated using:
- Model: `distilbert-base-uncased-finetuned-sst-2-english`
- Processing: Batch processing with optimization for efficiency
- Deduplication: Duplicate entries were removed based on text content
- **Filtering**: Only Positive and Negative sentiments retained for binary classification

## Usage

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("michsethowusu/kimbundu-sentiments-corpus")

# Access the data
print(dataset['train'][0])

# Check sentiment distribution
from collections import Counter
sentiments = [item['sentiment'] for item in dataset['train']]
print(Counter(sentiments))
```

## Use Cases

This dataset is ideal for:
- Binary sentiment classification tasks
- Training sentiment analysis models for Kimbundu
- Cross-lingual sentiment analysis research
- African language NLP model development
