Jianqiang Wang, Ph.D.
Department of Library and Information Studies
536 Baldy Hall
Jianqiang Wang earned his B.S. in applied physics from Xi’an Jiaotong University (China) and his M.S. in information science from the Institute of Scientific and Technical Information of China. After completing a one-year postgraduate exchange program at the University of Maryland, he worked on building the first-generation Chinese Web search engines at the Wanfang Data Company (Beijing). He returned to College Park, Maryland for his Ph.D. in library and information services. He also served as a graduate research assistant (1998–2005) and a postdoctoral faculty research associate at the University of Maryland Institute for Advanced Computer Studies. Dr. Wang joined the UB faculty in Fall 2006.
Dr. Wang’s research focuses on developing algorithms and techniques of information retrieval (IR) in a multilingual and multimodal environment and evaluating them in supporting users' access to and use of digital information. He has done extensive research in two special areas of IR: (1) cross-language information retrieval (CLIR), the problem of finding information written in one language in response to search requests written in another language, and (2) e-discovery, the problem of finding electronic business documents for purposes of litigation or government investigation. Dr. Wang’s major contribution to CLIR is the development of a cross-language meaning-matching model, which uses bidirectional translation knowledge automatically learned from parallel bilingual corpora. He also extended that work to the retrieval of spoken documents across the language boundary while studying information access to the Shoah Foundation’s digital collection of audio/video interviews with Holocaust survivors, rescuers, and witnesses. For e-discovery, Dr. Wang has studied the application and the effectiveness of state-of-the-art ranked retrieval technology, different query techniques, and various factors influencing users’ judgment of document relevance. His e-discovery work was partly supported by a grant from UB’s Baldy Center for Law and Social Policy.
Dr. Wang has published his research in Computer Speech and Language; Information Processing and Management; Information Retrieval; Transactions on Asian Language Information Processing; and Springer’s “Lecture Notes in Computer Science,” as well as in the conference proceedings of the Association for Computing Machinery’s Special Interest Group on Information Retrieval; American Society of Information Science and Technology; and the Text REtrieval Conference. He has served on two grant review panels for the U.S. National Science Foundation’s Division of Information and Intelligent Systems. During the 2012–2013 academic year, Dr. Wang was the interim chair of the Department of Library and Information Studies (LIS).
Recently, Dr. Wang has engaged in collaborative research on cross-language allusion detection with faculty members and Ph.D. students from the UB Department of Classics and the UB Department of Linguistics. He is also collaborating with his LIS colleagues on the problems of information retrieval for clinical decision support, as well as information retrieval based on context and user interests. He has actively participated in the discussion of big data for education, which is a newly identified research theme within GSE.
The courses that Dr. Wang most frequently teaches include: Database Systems, Information Systems Analysis and Design, and Introduction to Information Technology. In addition, he has taught two other courses: Digital Libraries, and Survey on Information Science and Services.
