Introduction: The concept and study of relevance has been a central subject in information science. Although research in information retrieval has been focused on topical relevance, other kinds of relevance are also important and justify further study. Motivational relevance is typically inferred by criteria such as user satisfaction and success.…

We study relevance judgment and user activities in a search session. We focus on ephemeral relevance--a contextual measurement regarding the amount of useful information a searcher acquired from a clicked result at a particular time--and two primary types of search activities--query reformulation and click. The purpose of the study is both…

Presents a new measure of retrieval evaluation called corrected precision, which refines the traditional measures of recall and precision by taking into account differences among users in their selectivity when judging document relevance. The formula for calculating corrected precision is explained, and results from an empirical study of relevance…

A study of logical reasoning ability of endusers searching a CD-ROM index and its correlation to searching performance was conducted at the University of Illinois at Urbana-Champaign. Findings showed a correlation between cognitive skills and citation selection and indicated that computer system design can be improved using a cognitive engineering…

Describes a study that addressed the problem of predicting pertinence of documents from citations. The difference between pertinence and relevance is discussed; the use of eye movement monitoring and verbal reports is explained; and citation viewing is discussed in terms of extensity, intensity, and motility.

This study examined the experiences of 59 novice end users with a multifile, full-text information retrieval system. A regression model was developed of the relative contributions of computer, system, and subject knowledge to search success as measured by user judgments of the relevance of retrieved documents. Results indicated all three variables…

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

Describes preliminary results of a study that examined the effect of individual differences on the use of CD-ROM databases by novice undergraduate users. Factors considered include age, sex, native language, major, computer literacy, computer affinity, personality traits, learning style, visual ability, and perceived usefulness of the system. A…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
