Peer reviewedSpink, Amanda; Goodrum, Abby; Robins, David – Information Processing & Management, 1998
Elicitations study during 40 mediated information retrieval (IR) interactions identified 1557 search intermediary elicitations within 15 purpose categories (requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous…

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 reviewedRothkegel, Annely – Information Processing & Management, 1995
A text production model is considered as an instrument for researching the writing strategies of abstractors. Within this framework, abstracting is a subtype of the writer's activities, which are described in terms of text actions. A computer system can be constructed that evaluates and/or supports human text production. (Author/AEF)

Introduces an evaluative framework for metasearch engine performance and illustrates its use in two experiments. Results are used to characterize some properties of leading search engines (as of 1998). Significant interactions were observed between search engine and two other factors: time of day and Web domain. (Author/AEF)
