Malagasy Sentiment Corpus

Dataset Description

This dataset contains sentiment-labeled text data in Malagasy 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: 1,338,704
• Positive sentiment: 744901 (55.6%)
• Negative sentiment: 593803 (44.4%)

Dataset Structure

Data Fields

• Text Column: Contains the original text in Malagasy
• 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

from datasets import load_dataset

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

# Access the data
