Speaker:
George Chang, Assistant Professor, Kean University
Candidate for Faculty Position in Computer Science
Structural Matching and Discovery in
Scientific/Document Databases and Web Mining
Pattern Matching has many applications in computational biology, computer vision, and data management. The data objects that we consider include strings, trees and graphs. These data types have many applications in scientific domains, including the representation of DNA sequences (strings), RNA secondary structures (trees), LaTeX/SGML/XML documents (trees), web pages (trees) and chemical compounds (graphs). Three systems, Pattern Matching and Discovery Toolkit (PMDT), Document Comparison Tools (DCT), and Web-based Approximate Querying System (WAQS), that are built on approximate pattern matching algorithms will be presented. The design and implementation along with querying languages and web crawling agents implemented in the systems will also be discussed.
Biographical Sketch: Dr. Chang holds a Ph.D. and M.S. in Computer and Information Science from the New Jersey Institute of Technology and dual B.S. degrees in Computer Science and Applied Mathematics and Statistics from the State University of New York at Stony Brook. He was a Special Lecturer in the Computer and Information Science Department at the New Jersey Institute of Technology before joining Kean University as an Assistant Professor in 1999. Dr. Chang is the lead author of the book Mining the World Wide Web - An Information Search Approach (Kluwer Academic Publishers, 2001) and has authored many journal and conference publications. His research interests include databases, bioinformatics systems, data mining, information retrieval, enterprise and mobile application development. He is a Redhat Certified Engineer and has just been inducted into The Honor Society of Phi Kappa Phi.
