Indian Language to Indian Language Machine Translation (IL-IL MT) 2010-2016
- IL-IL MT is a bidirectional Indian language to Indian language machine translation project. This project intends to develop 18 MT systems involving 9 Indian language pairs based on transfer approach. It is being developed in a consortium mode involving International Institute of Information Technology Hyderabad, University of Hyderabad, Institute of Information Technology (IIT) Bombay, IIT Kharagpur, Indian Institute of Science Bangalore, Anna University and Centre for Development Of Advanced Computing Pune. It is funded under Technology Development for Indian Languages (TDIL) Program by the Department Of Electronics and Information Technology (DeitY), Ministry Of Communications and Information Technology(MCIT), Government of India.
- Language Technology Laboratory at Centre for Applied Linguistics and Translation Studies(CALTS) has conducted the research and development for building Telugu-Hindi, Hindi-Telugu, Telugu-Tamil and Tamil-Telugu MTs. As principal investigator, Prof. G. Uma Maheshwar Rao coordinates this project and as an investigator I (Dr. K. Parameswari) carried out research and development in building Telugu-Tamil and Tamil-Telugu MT systems with the research team consisting linguists and computer scientists.
- My contribution to this project is mainly in building Transfer Grammars, Tamil Morphological Analyser & Generator, POS tagger, Chunker, Dependency parser, Multi Word Expression & Agreement Generation modules for Tamil and Telugu.
