Developed a document authoring system whereby authors may accurately prepare a semantic representation of a text for translation into minority languages. Developed text generation system for automatic translation of Biblical and community development documents. The Bible Translator's Assistant (www.thebibletranslatorsassistant.org) (aka Linguist’s Assistant) divides the difficult task of Bible translation into two separate tasks: 1. Annotate the Biblical text to remove all ambiguity by specifying the precise meaning of each word and by specifying the structure of each phrase and clause. 2. Automatically generate an initial draft translation from the annotated Biblical text using linguistic rules customized for a particular language. Members of The Bible Translator's Assistant team are currently helping produce accurate and natural translations of parts of the Bible in diverse languages; work is in progress in the Philippines and additional languages are scheduled to be added in Vanuatu.

Overview of WorkA. OntoSem text analyzer. The OntoSem text analyzer is a knowledge-based system that produces semantic representations of input text. The analyzer can be divided into four stages:1. preprocessing: morphological analysis and detection and interpretation of named entities, dates and numbers2. syntactic parsing3. basic semantic analysis in which the core meaning of the input text is determined and semantic dependencies established4. advanced semantic… Show more Overview of WorkA.

The analyzer can be divided into four stages:1. preprocessing: morphological analysis and detection and interpretation of named entities, dates and numbers2. syntactic parsing3. basic semantic analysis in which the core meaning of the input text is determined and semantic dependencies established4. advanced semantic analysis through various meaning procedures to determine, for example, textual coreference and detailed time informationB. Intelligent Agents, Medical Simulation and Tutoring The Maryland Virtual Patient (MVP) project is developing an agent-oriented environment for automating certain facets of medical education and certification. This environment is effectively a network of human and software agents, at whose core is a virtual patient – a knowledge-based model of a person with a disease. This model is implemented in a computer simulation. The virtual patient undergoes both normal and pathological processes in response to internal and external stimuli. Cognitively, it experiences symptoms, has lifestyle preferences, has memory (many of whose details fade with time), and communicates with the human user about its personal history and symptoms. Trainees can use the MVP simulation environment to interview a virtual patient, order lab tests, receive the results of lab tests from technician agents, receive interpretations of lab tests from consulting physician agents, posit hypotheses, clinical diagnoses and definitive diagnoses, prescribe treatments, follow-up after those treatments to judge their efficacy, and follow a patient’s condition over an extended period of time.

NLP and Machine Translation

In seemingly another life, I was a software engineer at McDonnell Douglas in St. Louis. I worked on the flight control software for the F-15. I was involved in all aspects of software development, including planning, design, coding and testing.
