Jacek Ambroziak - Jacek Ambroziak joined Sun Microsystems' XML Technology Center in 1999, where he's been applying his extensive background in natural language technologies, Java, Jini, and XML to the problems of XML document search and retrieval. Jacek has been with Sun Microsystems since 1992, when he became a Research Scientist in the Knowledge Technology Group of Sun Laboratories. While in this position, Jacek worked on an approach to text search called "conceptual indexing," which combines techniques from knowledge representation and natural language processing to enable a computer to systematically organize relationships among concepts. Jacek architected and implemented modular semantic lexicons, co-developed a modular text processing pipeline, and built a highly efficient conceptual database and search engine. Subsequent to this work he designed and implemented in Java a full-text search engine that became part of Sun's JavaHelp facility. Jacek received his Ph.D. in Computer Sciences in 1990 from the Polish Academy of Sciences in Warsaw. He worked as a Research Associate in the Academy's Institute of Fundamental Technological Research and, before joining Sun, was a Visiting Scientist in the College of Engineering at Cornell University. Jacek's recent publications include a presentation at the XTech 2000 Conference earlier this year entitled "An XML-Based Approach to the Control of XML Document Indexing," a 1998 SunLabs Report with William Woods on "Natural Language Technology in Precision Content Retrieval," and a presentation on "Conceptually Assisted Web Browsing" given at the WWW6 Conference in 1997.
