Salim Roukos' research areas at IBM Research have been in statistical machine translation (SMT), information extraction, statistical parsing and statistical language understanding. Salim is the PI on the DARPA GALE and the newer BOLT projects to develop both robust translation systems for speech and text applications and question-answering systems from multilingual content. A new activity concerns the development of Clinical Language Understanding for electronic health records. He also has led the effort to create IBM's offering of Real-Time Translation Services (RTTS), a platform for enabling real-time translation applications such as multilingual chat and on-demand document translation. Salim led the group that created IBM's ViaVoice Telephony product, the first commercial software to support full natural language understanding for dialog systems in 2000, and more recently the first SMT product for Arabic-English translation in 2003.
