Large-Scale Text Processing: Intelligent Computer Systems that Understand Human Languages

Lucja M. Iwanska
Chief Scientist/Chief Technology Officer, LxLinks Inc.

Abstract

Intelligent computer system, a general-purpose knowledge representation and reasoning system simulating closely unique, highly desirable computational characteristics of natural is discussed. The system has a human-like capability to understand and process arbitrary textual data in a number of different languages.

Examples of research-driven practical, large-scale information and knowledge processing tasks are presented: automatic knowledge acquisition, meaning-based text mining/information extraction, question answering, summarization, and document comparison, merging, and classification.

A brief overview of the uniform computational mechanism of representing and reasoning with meaning of natural language and different types of knowledge, including taxonomic, probabilistic, temporal and some aspects of spatial knowledge is also presented.

Bio
Lucja is an expert on natural language processing, knowledge representation and reasoning, and machine learning, the areas of Computer Science concerned with developing intelligent information systems. Her chief research contribution is a unique computer model that simulates human understanding, processing, acquiring, and utilizing information and knowledge expressed in English and other natural languages. Her many technical publications include journal and conference articles and books. Lucja earned her PhD from the University of Illinois at Urbana-Champaign, Computer Science, 1992, and her MS from Moscow Institute of Technology, Automation and Computer Science, 1982. She holds a Chief Scientist/Chief Technology Officer position at LxLinks, Inc., 2002-present, she was its President&CEO, 2000-2002. Prior to LxLinks, she was an Assistant Professor in the Dept. of Computer Science, Wayne State University, Detroit, MI, 1993-2000, and a Research Scientist in the Artificial Intelligence Laboratory, GE Research & Development Center, Schenectady, NY.
