Vita
Wen-Lian Hsu received a B.S. from the Department of Mathematics, National Taiwan University in 1973. He received an M.S. and a Ph.D. in operations research from Cornell University in 1978 and 1980, respectively. From 1979 to 1980, he worked as a research associate in the Center for Operations Research and Econometrics (CORE) at Universite Catholique de Louvain, Belgium. In 1980, he joined Northwestern University as an assistant professor and was promoted to tenured associate professor in 1986. He joined the Institute of Information Science as a research fellow in 1989.

Dr. Hsu's earlier research while in Northwestern University is focused on graph algorithms. His main contribution is on perfect graphs and special classes of intersection graphs. Most of his publications appear in JACM and SIAM J. Computing. Recently, he invented the PC-tree data structure to design very efficient algorithms in planar graphs and intersection graphs. In the meantime, he has applied similar techniques to tackle computational problems in Biology such as error-tolerant algorithms in DNA sequence analysis.

Right after joining the institute in 1989, he initiated the project ``intelligent Chinese phonetic input system'' (in cooperation with K. J, Chen), aiming at resolving a major bottleneck in the computerization of Chinese language -- the input method. A software resulted from this project, 自然輸入法(GOING), achieved a hit ratio close to 96% and was selected as one of the ten best Chinese computer products of Taiwan in 1993. This software has been widely used in Taiwan and the number of downloads in PC Home web station is close to 600,000. Later, he moved into the research of Intelligent Agent on the Internet, and produced the Math. Problem Solving Agent in 1997, and a Chinese natural language Q & A system, @skbots, in 1999. He is currently working on DNA sequence analysis, Genome knowledge base and intelligent knowledge management systems.

Dr. Hsu has published in various top-notch journals in discrete mathematics, operations research and computer science. He has been invited to deliver lectures in many international conferences. He has been the conference chairs of ISAAC'91 and COCOON'98, ITS’06 and has been involved in the editorship of the following journals: Managing Editor of Journal of Information Science (1995-2001), International Journal of Foundation of Computer Science (1993-2002), Information Processing Letters (2001-), and International Journal of Bioinformatics Research and Applications (2005-). He has been the president of the Artificial Intelligence Society in Taiwan (2001-2002).

Research Interests
Our main research topic is natural language understanding. Nearly all of the following systems require certain understanding capability to achieve high precision rates: semantic search on the web, Chinese voice input and output, spelling checker and machine translation. Our Chinese input system--GOING, which automatically translates a chu-in sequence into characters with a hit ratio close to 96%, is widely used in Taiwan. It received the Distinguished Chinese Information Product Award（中文傑出資訊產品獎）in 1993. In PC Home software download area, GOING has been downloaded 600,000times. Within the top 10 download software, it is the only one developed domestically.

Our model for concept understanding can utilize heterogeneous knowledge representation systems. We have extended our model to that on Internet intelligent agents, especially on the database agents. These software agents will become indispensable in the semantic search engine and the electronic commerce on the Internet. Another direction we are moving into is the development of educational tutoring systems. We have successfully implemented a system that can understand and solve (and explain how so solve) the mathematics word problems of primary school (grade 3).

Our major achievement is the development of a knowledge representation kernel, InfoMap, for the semantic analysis of natural language, which can be applied to a wide variety of application systems. We are currently utilizing this kernel to develop an Intelligent Knowledge Management System over the World Wide Web. There are several technology transfer programs currently going on with private companies.

In DNA sequence analysis, we have been studying the physical mapping and the clone assembly problem. When the experimental error is within 15%, we have developed an error-tolerant algorithm for the clone assembly problem (as well as the physical mapping problem) that can determine the relative positions of each clone (respectively, each probe) given the clone overlapping relationships. By combining our knowledge management tools, InfoMap, and natural language agent, we are currently constructing a Question Answering system for genomic and proteomic knowledge. We shall further extend this system to help biologist to execute certain natural language scripts automatically in their dry labs. Finally, we shall utilize InfoMap to facilitate the accurate search of various relationships in biological literature.
