Yang, Meng; Wildemuth, Barbara M.; Marchionini, Gary; Wilkens, Todd; Geisler, Gary; Hughes, Anthony; Gruss, Richard; Webster, Curtis – Proceedings of the ASIST Annual Meeting, 2003
Proposes two general classes of user tasks-recognition tasks and tasks requiring inference-for which performance measures were developed. The measures include graphical object recognition, textual object recognition, action recognition, free-text gist determination, multiple-choice gist determination and visual gist determination. Results from two…

Peer reviewedMarchionini, Gary – Journal of the American Society for Information Science, 1992
Discusses essential features of interfaces to support end-user information seeking. Highlights include cognitive engineering; task models and task analysis; the problem-solving nature of information seeking; examples of systems for end-users, including online public access catalogs (OPACs), hypertext, and help systems; and suggested research…

Peer reviewedMarchionini, Gary; Nitecki, Danuta A. – College and Research Libraries, 1987
Discusses changes in academic libraries resulting from evolving technologies, and the need to train library patrons and staff in the use of electronic information systems. A review of the training literature and the results of three projects for supporting patron use of online systems are reported. (CLB)

Peer reviewedMarchionini, Gary; Mu, Xiangming – Information Processing & Management, 2003
Describes a series of user studies used to advance understanding of how people use electronic tables (E-tables) and inform the development of a Web-based statistical table browser for use by non-specialists. Results of needs assessment, prototype development, and user studies provide a foundation for understanding E-tables in general and guiding…

Peer reviewedMarchionini, Gary – Journal of the American Society for Information Science and Technology, 2002
Describes how user interfaces for the Bureau of Labor Statistics (BLS) web site evolved over a 5-year period along with the larger organizational interface and how this co-evolution has influenced the institution. Interviews with BLS staff and transaction log analysis are the foci of this study, as well as user information-seeking studies and user…

Peer reviewedMarchionini, Gary; Fox, Edward A. – Information Processing & Management, 1999
Introduces the nine papers in a special issue focusing on progress toward digital libraries. Articles fall into three categories: history and activities about digital libraries (DL); understanding digital library users; and extending and integrating through digital libraries. (AEF)

Ding, Wei; Soergel, Dagobert; Marchionini, Gary – Proceedings of the ASIS Annual Meeting, 1999
Investigates the information representation power of different modalities in the video data in order to collect empirical evidence for video surrogate creation and thus better support effective video browsing and information retrieval. Three types of video surrogates were created and compared under two user tasks--verbal comprehension and visual…

Peer reviewedMarchionini, Gary; And Others – Library and Information Science Research, 1993
Describes four studies that explored how search experts and domain experts conducted searches in full-text, end-user search systems. Problem definition/expectation; query formulation; examination and extraction; reflection, stopping, and search monitoring; and system effects are examined for each study. (26 references) (EA)
