Chen, Hsinchun; Li, Xin; Chau, M.; Ho, Yi-Jen; Tseng, Chunju – IEEE Transactions on Education, 2009
With the advent of the World Wide Web, many business applications that utilize data mining and text mining techniques to extract useful business information on the Web have evolved from Web searching to Web mining. It is important for students to acquire knowledge and hands-on experience in Web mining during their education in information systems…

Alleviating Search Uncertainty through Concept Associations: Automatic Indexing, Co-Occurrence Analysis, and Parallel Computing.
Peer reviewed Peer reviewed
Chen, Hsinchun; Martinez, Joanne; Kirchhoff, Amy; Ng, Tobun D.; Schatz, Bruce R. – Journal of the American Society for Information Science, 1998
Grounded on object filtering, automatic indexing, and co-occurrence analysis, an experiment was performed using a parallel supercomputer to analyze over 400,000 abstracts in an INSPEC computer engineering collection. A user evaluation revealed that system-generated thesauri were better than the human-generated INSPEC subject thesaurus in concept…

Chau, Michael; Zeng, Daniel; Chen, Hsinchun – 2001
Searching for useful information on the World Wide Web has become increasingly difficult. While Internet search engines have been helping people to search on the Web, low recall rate and outdated indexes have become more and more problematic as the Web grows. In addition, search tools usually present to the user only a list of search results,…

Information Navigation on the Web by Clustering and Summarizing Query Results.
Peer reviewed Peer reviewed
Roussinov, Dmitri G.; Chen, Hsinchun – Information Processing & Management, 2001
Reports an approach to interactive information seeking that is grounded in the idea of summarizing query results through automated document clustering. The authors' prototype acted as an intermediate layer between the user and a commercial Internet search engine. Data was processed from 36 users and it was concluded that the prototype improved…

Moving Digital Libraries into the Student Learning Space: The GetSmart Experience
Peer reviewed Peer reviewed
Direct linkDirect link
Marshall, Byron B.; Chen, Hsinchun; Shen, Rao; Fox, Edward A. – Journal on Educational Resources in Computing, 2006
The GetSmart system was built to support theoretically sound learning processes in a digital library environment by integrating course management, digital library, and concept mapping components to support a constructivist, six-step, information search process. In the fall of 2002 more than 100 students created 1400 concept maps as part of…

Cognitive Process as a Basis for Intelligent Retrieval Systems Design.
Peer reviewed Peer reviewed
Chen, Hsinchun; Dhar, Vasant – Information Processing and Management, 1991
Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…
