Conceived, prototyped, and implemented a language generation system with novel capabilities for variation, complex natural dialog, and coordination with the emotion and affect of the interactive character it is speaking for. Conceived and specified for team implementation a novel language understanding system that uses the same linguistic resources as the.

Designed and implemented event-driven architecture for spoken dialog systems integrating speech recognition engines (ASR), dialog management using Collagen, and text-to-speech (TTS) in a framework that facilitated easily changing choice of speech engines. Evaluated alternative TTS systems, judging relative intelligibility and prosody. Conceived and.

Designed and implemented Java-based client-side grammar-directed editor. Responsible for internationalization including Unicode, Asian fonts, and character encodings. Responsible for encryption facilities for client and server authorization and security and associated customer issues. Handled bug fixes and customer issues anywhere within massive Lisp-based.

Adjunct position for collaboration on basic research into the compositional semantics of natural language and bi-directional language processing. Designed techniques for language parsing that do not require all semantic patterns to be created in advance. Developed web-based system for viewing students’ transcripts and progress towards meeting University.

Conceived and implemented a robust and efficient system for extracting targeted information from unrestricted English news articles from online information ser¬vices. Developed high-performance parsers, grammars and semantic models. Prepared application interfaces of the system for clients doing document categorization and doing information extraction to.

Developed an integrated system of techniques permitting the analysis of unrestricted English text: application to person/company/title sublanguage in the Wall Street Journal. Extensive product and development planning. Advised higher management on technical feasibility and time-lines.

Reviewed and critiqued system designs, product and marketing plans. Acted as the go-between for management and technical staff. Presentations to clients and potential investors. Carried out due-diligence evaluations. Conceived and prototyped innovative designs for semantic grammar parsing and analysis. Prepared multi-client study on hardware and software.

Directed seven students through to their Ph.D.'s with topics in language generation, ICAI tutoring, planning, design environments, distributed operating systems, and decision support systems. Taught courses in AI, vision robotics and brain theory, natural language processing, language generation, com¬mon-sense reasoning, Lisp, AI-system design, and.

Conceived, designed, and implemented the natural language generation system “Mumble”, subsequently carrying it through fourteen years of evolution. Wrote systems for program cross-indexing, Lisp dialect translation, and customized entry to databases. Redesigned Winograd's English grammar for SHRDLU. Research into psycholinguistic models of generation.
