Introduction to Wei-Tek Tsai (Taiwan): Wei-Tek Tsai is from Taiwan, China. His ID number for Mainland Travel Permit for Taiwan Residents is 10167041. He is currently a professor at the School of Computer Science and Engineering, Beijing University of Aeronautics and Astronautics. In 1979, he received his Bachelor of Science degree in computer science from the Massachusetts Institute of Technology and MS and Ph.D. degrees in computer science from the University of California at Berkeley in 1982 and 1986. He has taught for more than 30 years in the Department of Computer Science at the University of Minnesota and Arizona State University and has supervised more than 80 students to graduate with Ph.D. degrees. He is the director of the Laboratory of Computer Science and Engineering at Arizona State University.

So far, Professor Wei-Tek Tsai has published over 400 papers and 5 monographs. His research fields include service-oriented computing, software engineering, cloud computing, crowdsourcing, and blockchain. He has served as the chairman of over 30 international conferences as well as the leader of the EU Smart City and several software engineering and service-oriented computing projects in the United States. Professor Wei-Tek Tsai is also the vice chairman of the expert committee of China OSS Promotion Union and a senior researcher at the Institute of Industrial and Information Technology Law.

Research interest:

1. Software engineering: He took the lead in proposing and realizing the object-oriented testing method, and his research papers were published in international journals such as the Journal of Object-Oriented Programming and Communications of ACM and were included in the classic software engineering textbook R. S. Pressman's Software Engineering: A Practitioner's Cited by Approach. He proposed the influential regression testing technology and practice methods, of which the related results were published in Communications of the ACM and were cited by the main software engineering textbook Software Engineering by Ian Sommerville. He also proposed systematic point-to-point test and analysis methods, which were adopted by the U.S. Department of Defense for the Y2K test of the system. In addition, both a rapid test and a safety-tipping point test method for embedded systems were proposed, which were adopted by medical instrument manufacturers such as Guidant Widespread adoption. It can save nearly 70% of software development costs.

2. Database system: A framework for evaluating multi-level security concurrency control algorithm and a specific protocol are proposed. The results are of great significance in the field of database security. The paper of this study was published in IEEE Transactions on Knowledge and Data Engineering. He also proposed a performance security analysis method for medical instruments, which was published in IEEE Computer and adopted by medical instrument companies.

3. Software Maintenance: The software maintenance method based on data correlation was first proposed by Professor Tsai, which has many advantages compared with the traditional method of control flow analysis. Papers have been published in international journals such as the Journal of Software Maintenance-- Research and Practice. The results were adopted by Fujitsu, which developed a Y2K software testing tool based on this method and published a monograph in Japanese. At the same time, US WEST also applied this approach to software maintenance, solving a problem that had been plaguing the company for 15 years.

4. Service-Oriented Computing: Professor Tsai and the ASU Software Research Laboratory under his leadership have been conducting research on SOA software engineering methods and techniques since 2002. In recent years, more than 100 related papers and 3 monographs have been published in international journals and conferences. As a pioneer in this field, he was one of the first scholars to conduct research on the SOA lifecycle process, SOA collaborative verification and validation, SOA modeling, SOA simulation, SOA data traceability, etc., and has a significant impact on the field. According to Google Scholar, Professor Tsai’s research is leading in the following areas: “Service-Oriented Software Testing”, “Service-Oriented Simulation”, “SOA Application Architecture”, and “SOA lifecycle process”, “Service-Oriented Systems Engineering”. The results of his prospective research have been widely cited, including the extension and variation of SOA architecture, and a series of framework models, such as CCSOA (Consumer-Centric SOA), UCSOA (User-Centric SOA), ICSOA (Interface-Centric SOA), and RTSOA (Interface-Centric SOA). Moreover, he was the first to propose the classification of SOA application architecture and conducted an in-depth discussion on the SOA dynamic architecture. He was also the first to explore the service testing problem, propose the SOA collaborative testing infrastructure WebStrar, and propose numerous SOA testing methods and techniques. He was the first to apply ontology technology to the software development process and propose an ontology model based on architecture for software reuse. He worked with Researcher Jin Zhi, a researcher at the Institute of Mathematics, Chinese Academy of Sciences, to propose a new process and framework for SOA requirements engineering.

5. Software Services: Prof. Tsai is a highly influential scientist in this field. In the past five years, he has published 25 papers on SaaS and developed many latest SaaS technologies, such as SaaS testing techniques, SaaS simulation architecture, SaaS modeling techniques, TaaS (Testing as a Service), and test algebra for parallel combinatorial testing, adaptive combinatorial testing methods for tenant application testing, service-oriented SaaS, etc.
