Machine translation (MT) is a subfield of natural language processing (NLP) that focuses on automatically translating text from one language to another. This tutorial will guide you through the core concepts, models, and applications of MT.
Key Concepts
- Language Pairs: MT systems work with pairs of languages, such as English to French or Chinese to Spanish.
- Statistical vs. Neural Models: Traditional methods relied on statistical analysis, while modern approaches use neural networks (e.g., RNNs, Transformers).
- Alignment: Matching words or phrases between source and target languages to build translation mappings.
Popular Models
- Recurrent Neural Networks (RNNs): Early models using sequence-to-sequence architectures.
- Transformers: State-of-the-art models leveraging self-attention mechanisms for parallel processing.
- Sequence-to-Sequence (Seq2Seq): A foundational framework for generating translated text.
Applications
- Real-Time Translation: Used in apps like Google Translate for instant language conversion.
- Document Localization: Translating entire documents for international audiences.
- Cross-Lingual Search: Enabling search across multiple languages in databases.
