Research and Development in Audio Comparison, Search, Display, and Monitoring

1997 to 2003 at Comparisonics

• Developed a robust algorithm for measuring the similarity of sounds; this algorithm emulates the human perception of sound similarity and has many applications including:
  • audio/video searching and editing
  • machinery monitoring and industrial quality control
  • security, surveillance, and forensics
• Developed a content-based audio retrieval technology for searching audio data for sounds that are similar to an example sound (also known as a "sounds-like search" or "query by sound example")
• Invented and patented the techniques of coloring the audio waveform display to convey the frequency content of an audio signal and of navigating the waveform display based on sound similarity (U.S. Patent No. 6,184,898: Waveform Display Utilizing Frequency-Based Coloring and Navigation)
• Led the development of FindSounds.com, the first Web search engine for sound effects:
  • enables audio files on the Web to be retrieved by a keyword search or sounds-like search; first Web search engine with content-based audio retrieval; "hits" are represented by colored waveform displays
  • currently processes each month more than 2,000,000 sound searches for more than 300,000 users
  • profiled on television and radio, and in magazines and newspapers; selected by PC World magazine as one of 50 Web sites in its 2002 Best of the Web review
• Led the development of FindSounds Palette, a software program that extends the Web search capabilities of FindSounds.com and enables users to catalog and search audio files on their hard drive:
  • incorporates database, Internet communications, and e-commerce with audio playing, recording, and editing
  • multiplies the available sounds by searching for sounds produced by changing the playback speed of audio files; first audio retrieval system to offer this feature
• Developed a machinery-monitoring system that can listen to the sound of any machine or environment, and in real time, detect and report the occurrence of specific sounds or changes in sound; this pattern-recognition system has widespread application in industrial environments

• Developed new performance measures for optical character recognition (OCR) systems, for character, word, non-stopword, and phrase accuracy, and others
• Made theoretical and applied contributions in sequence comparison and utilized them to implement the new OCR performance measures
• Wrote Ph.D. Dissertation, Measuring the Accuracy of Page-Reading Systems (PDF), which formally defines the new OCR performance measures and presents the sequence-comparison results on which they are based
• Created the OCR Experimental Environment, a unique software system with a distributed architecture for large-scale, automated testing of OCR systems
• Conducted for five consecutive years the internationally-recognized UNLV Annual Test of OCR Accuracy, the first large-scale independent evaluations of commercial OCR systems
• Created the ISRI Voting Machine, the first OCR system to combine the outputs of multiple commercial OCR systems to produce a more accurate single output
• Raised funds for ISRI:
  • one of three principal investigators for a project to extend the OCR Experimental Environment to evaluate foreign-language OCR systems using Unicode; this project received $1,500,000 over a three-year period from the U.S. Department of Defense
  • co-developed the ISRI Industrial Affiliates Program which raised approximately $150,000/year for a five-year period; sponsors included Adobe, Hewlett Packard, Xerox, and others
• Served on the Board of Advisors of the Federal Intelligent Document Understanding Laboratory of the U.S. Central Intelligence Agency

• Led the design of Simscript III, an object-oriented programming language for computer simulation based on Simscript II.5, and developed part of the Simscript III compiler
• Collaborated with Nobel laureate Dr. Harry M. Markowitz, who developed the original versions of Simscript in the 1960s
• Designed and implemented the Simscript Database Connectivity feature, which enables Simscript programs to access relational databases

• Conducted an in-depth technical evaluation of commercial database products and text-retrieval systems and provided recommendations to the U.S. Department of Energy

• Co-invented Modsim, an object-oriented programming language for computer simulation, and wrote the first Modsim compiler
• Led the team that created SimGraphics II, a library of object classes enabling Modsim programs to draw graphs and graphics, animate simulations, and provide graphical user interfaces (GUIs) in a platform-independent way:
  • similar to but pre-dates the Microsoft Foundation Classes (MFC) and Java's Abstract Windowing Toolkit (AWT)
  • supported "write once, run anywhere" of graphical applications several years before Java
• Developed a code generator and a portable run-time library for the Simscript II.5 programming language

• Created TED, the first-known table editor for relational databases; a table editor enables users to enter, edit, and delete rows of database tables and is today a standard component of every database management system

• Developed Oracle's first SQL precompiler as Oracle's 40th employee (today Oracle employs 86,000 people); worked with Oracle founders Larry Ellison and Bob Miner

• Designed and implemented the Language Preprocessor for the IBM DB/DC Data Dictionary; this software product received an IBM award for its design

• Participated in relational database research and development
• Wrote Master's Thesis, The Null Value in Relational Databases, including the first proposed extension of the relational model to support null values while preserving the transitivity of functional dependencies
