Statistical Machine Translation: Resources for Indian languages

At the Center For Indian Language Technology, IIT Bombay, we have hosted Shata-Anuvaadak (100 Translators), a broad coverage Statisitical Machine Translation system for Indian languages. It currently supports translation between 11 Indian languages:

  •     Indo-Aryan languages: Hindi, Urdu, Bengali, Gujarati, Punjabi, Marathi, Konkani
  •     Dravidian languages: Tamil, Telugu, Malayalam
  •     English

It is a Phrase-Based MT system with pre-processing and post-processing extensions. The pre-processing includes source-side reordering for English to Indian language translation. The post-processing includes transliteration between Indian languages for OOV words. The system can be accessed at:
