Boris Katz was born in Chisinau, Moldova. He was able to get out of USSR with the help of a U.S. senator, before the end of the cold war. Currently, he is a Principal Research Scientist (Computer Scientist) at the MIT Computer Science and Artificial Intelligence Laboratory and head of the Laboratory's InfoLab Group. His research interests include natural language generation and understanding, machine learning and intelligent information access.
Over the last several years Boris Katz has been developing the START natural language system that allows the user to access various types of information using English.
The START system responds to natural language queries with answers in text, pictures, and other media. START's sentence-level natural language parsing relies on a number of mechanisms to help it process the huge, diverse resources available on the World Wide Web. Blitz, a hybrid heuristic- and corpus-based natural language preprocessor, enables START to integrate a large and ever-changing lexicon of proper names, by using heuristic rules and precompiled tables of symbols to preprocess various highly regular and fixed expressions into lexical tokens. LaMeTH, a content-based system for extracting information from HTML documents, assists START by providing a uniform method of accessing information on the Web in real time. These mechanisms have considerably improved START's ability to analyze real-world sentences and answer queries through expansion of its lexicon and integration of Web resources.

- A Knowledge Entry System for Subject Matter Experts (http://www.ai.sri.com/project/SHAKEN)
The goal of SHAKEN project is to enable subject matter experts, without any assistance from AI technologists, to assemble the models of processes and mechanisms so that questions about them can be answered by declarative inference and simulation.
