Liu, Ming-Chi; Huang, Yueh-Min; Kinshuk; Wen, Dunwei – Educational Technology Research and Development, 2013
It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image…

Kim, Yong-Mi – ProQuest LLC, 2011
In recent years, tags have become a standard feature on a diverse range of sites on the Web, accompanying blog posts, photos, videos, and online news stories. Tags are descriptive terms attached to Internet resources. Despite the rapid adoption of tagging, how people use tags during the search process is not well understood. There is little…

Bak, Peter; Meyer, Joachim – Behaviour & Information Technology, 2011
Information systems increasingly provide options for visually inspecting data during the process of information discovery and exploration. Little research has dealt so far with user interactions with these systems, and specifically with the effects of characteristics of the displayed data and the user on performance with such systems. The study…

Vega-Gorgojo, Guillermo; Bote-Lorenzo, Miguel L.; Asensio-Perez, Juan I.; Gomez-Sanchez, Eduardo; Dimitriadis, Yannis A.; Jorrin-Abellan, Ivan M. – Computers & Education, 2010
This paper introduces Ontoolsearch, a new search system that can be employed by educators in order to find suitable tools for supporting collaborative learning settings. Current tool search facilities commonly allow simple keyword searches, limiting the accuracy of obtained results. In contrast, Ontoolsearch supports semantic querying of tool…

Schultz, Leah – ProQuest LLC, 2009
This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait,…

Hall, Angela M. – 1972
The object of this study was to record detailed descriptions of the procedure employed in a number of actual searches of the indexes to Science Abstracts. From these data, any problems which the users encounter would be shown and any areas in which the indexes might be better structured to suit the users' requirements might be determined.…

Morse, Philip M. – 1970
Search theory, originally developed for antisubmarine search, is applied to the scanning of library shelves for books of interest, or of a computerized abstract catalog for items of immediate application. Procedures optimizing the information to be found are discussed, as well as methods whereby the operational parameters can be measured. The…

Zull, Carolyn G.; Baumanis, George J. – 1967
A study of relevance through comparison of texts judged by users is reported. The relevant set of documents for each information request was characterized by textual properties. The validity of procedures and interpretations is discussed. Consideration is given to possible mechanization of the process and its possible usefulness in development of…
