# Multilingual Sentences

Dataset contains sentences from 50 languages, grouped by their two-letter ISO 639-1 codes. The "all" configuration includes sentences from all languages.

## Dataset Overview

Multilingual Sentence Dataset is a comprehensive collection of high-quality, linguistically diverse sentences. Dataset is designed to support a wide range of natural language processing tasks, including but not limited to language modeling, machine translation, and cross-lingual studies.

## Methods

Rigorous methodology consisted of three main stages: text preprocessing, language detection, and dataset processing.

### Text Preprocessing

Sophisticated text cleaning pipeline using the textacy library, which included:

- Removal of HTML tags, email addresses, URLs, and emojis
- Unicode and whitespace normalization
- Standardization of punctuation and word formats

### Language Detection

Google CLD3 library utilized for accurate language identification:

- Implemented NNetLanguageIdentifier
- Configured for processing texts between 0-1000 bytes
- Included reliability assessment for each language detection

### Dataset Processing

Workflow for dataset creation involved the following steps:

1. Streamed loading of the LinguaNova multilingual dataset
2. Application of the text preprocessing pipeline
3. Sentence segmentation using PyICU for accurate boundary detection
4. Quality filtering:
   - Length constraint (maximum 2048 characters per sentence)
   - High-reliability language verification
5. Extraction of unique sentences
6. Random shuffling for unbiased sampling
7. Generation of language-specific files

## Technical Details

### Libraries and Tools

- textacy: Advanced text preprocessing
- Google CLD3: State-of-the-art language detection
- Hugging Face datasets: Efficient data handling and processing
- SentenceBreaker: Accurate sentence segmentation

### Implementation Notes

- Process was executed consistently across all 50 languages to ensure uniformity and high quality in the multilingual dataset preparation.
- Special attention was given to maintaining the integrity of each language's unique characteristics throughout the processing pipeline.

## Data Splits

Dataset is organized into the following splits:

- Individual language files: Contains sentences for each of the 50 languages
- "all" configuration: Aggregates sentences from all languages into a single dataset

## Limitations and Biases

While extensive efforts were made to ensure dataset quality, users should be aware of potential limitations:

- Language detection accuracy may vary for very short texts or closely related languages
- Dataset may not fully represent all dialects or regional variations within each language
- Potential biases in the original LinguaNova dataset could be carried over

## Ethical Considerations

Users of this dataset should be mindful of:

- Potential biases in language representation
- Need for responsible use in AI applications, especially in multilingual contexts
- Privacy considerations, although personal identifiable information should have been removed
