个人简介
Expertise
Information Discovery and Retrieval – learning, navigating and manipulating structure and
information in unstructured or semi-structured document bases.
Experience
2001-present: Chief Technology Officer, DigitalMC, Pittsburgh, PA.
DigitalMC performs digital signal analysis and datamining for a variety of products in areas
including audio fingerprinting, audio content retrieval, listener preference modeling, music
recommendation, and statistical market research.
• Developed core algorithms for audio fingerprinting, audio retrieval and music
recommendation (patents pending).
• As chief architect and acting manager of technical staff, directed development of product
offerings by team of eight researchers and software developers.
• Identified, evaluated and pursued technical opportunities for DigitalMC in digital content
delivery, media indexing and retrieval markets.
2000-2001: Principal Scientist, Burning Glass Technologies, Pittsburgh, PA.
Burning Glass Technologies is a leading provider of information extraction and predictive
analytics software infrastructure for the Human Capital Management market, applying statistical
natural language processing and information retrieval to predict the degree of match between a
job candidate and the requirements of a position.
• Lead development of probabilistic model for inferring skills and requirements from stated
skills/requirements in job postings and resumés.
• Developed joint probabilistic model for mapping resumése (“facilitated workplace hygiene”)
and postingese (“must be neat”) to common conceptual framework.
• Led development of techniques for learning taxonomies of competencies from a corpus of
examples, adaptive spelling correction and identification of canonical forms from free text.
1999-2000: Research Scientist, Justsystem Pittsburgh Research Center, Pittsburgh, PA.
Research arm of Justsystem Corporation, a leading vendor of document processing, knowledge
management and information retrieval software in Japan.
• Developed algorithms for learning to find answers to natural language queries in large
matched question-answer corpora.
• Developed techniques for learning, navigating and manipulating the structure of otherwise
unstructured document bases.
• Developed algorithms for efficiently generating personalized models of document authority
and relevance from few examples.
• Developed probabilistic bibliometrics, and the first published algorithm for reasoning about
document contents and links using a unified probabilistic model. Applications in adaptive
web spidering, clustering, cross-language retrieval and dynamic hypertext generation.
1995-1998: Senior Research Scientist, Adaptive Systems Group, Harlequin, Inc.,
Cambridge, MA and Menlo Park, CA.
Acquired by Global Graphics; a provider of digital pre-press document workflow solutions,
software tools, and information management and visualization systems (spun off as Xanalys).
• Core Architect on adaptive document workflow optimization system for digital pre-press
industry. Led design of scheduling and resource estimation components, which used machine
learning and real-time adaptive scheduling. Managed project involvement of 5 Ph.D.-level
members of the Adaptive Systems Group.
• Initiated and served as Lead Designer on project to develop document/information
management and retrieval system. Designed, implemented and demonstrated several simpler
prototype document retrieval/clustering systems as testbeds.
• Invented, and led design and implementation of adaptive memory management system for
dynamic memory allocation.
1989: IBM Thomas Watson Research Center, Yorktown Heights, NY.
1988: Visiting Researcher, Hitachi Central Research Laboratory, Tokyo.
1986: Research Institute for Advanced Computer Science, NASA Ames, Moffett Field, CA.
