Hierarchical folders have been widely used for managing digital files. A well constructed hierarchical structure can keep files organized. A parent folder can have several subfolders and one subfolder can only reside in one parent folder. Files are stored in folders or subfolders. Files can be found by traversing a given path, going through…

The article proposes a self-study system which suggests web links to learners. The suggestions depend upon the learner's chosen competences selected from a competence structure for a particular knowledge domain. Three experiments were conducted, where the first compared the perceived usefulness and value of the links generated by different…

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…

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…

Differences in judged relevance of Educational Resources Information Center (ERIC) abstracts identified by two different information systems were investigated. A national semi-private educational service agency which utilizes mechanical searching of the research literature was one information system, while the other was a regional,…

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,…

Compares results of two empirical studies in which relevance criteria were elicited from individuals seeking information to resolve information problems. Results provide evidence that a finite range of criteria exists and that these criteria are applied consistently across types of information users, problem situations, and source environments.…

As the fourteenth report in a series describing research in automatic information storage and retrieval, this document covers work carried out on the SMART project for approximately one year (summer 1967 to summer 1968). The document is divided into four main parts: (1) SMART systems design, (2) analysis and search experiments, (3) user feedback…

The performance of CA Condensates" (CC) and Chemical Titles" (CT) based on analysis of precision and relative recall CT/CC" for 46 search profiles was studied for one year. The results are discussed in terms of the value of the systems as seen from the users' and the documentalist's point of view. (13 references) (Author/NH)

A comparison of costs for computer-based searching of Psychological Abstracts and Educational Resources Information Center (ERIC) systems by the New York State Library at Albany was produced by combining data available from search request forms and from bills from the contract subscription service, the State University of New…

Describes a series of studies conducted to determine how ERIC online searchers were using free and controlled vocabulary in their search statements and to understand relevance implications of the resultant differences. (SW)

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…

Discusses ways to improve and standardize intellectual access to electronically published historical documents. Highlights include metadata; information retrieval; the need for user studies; the need to assess implications for change in publication management; and the need to compare empirically various technological approaches to access to…

Describes a study which compared patron success in finding the same group of titles in the online catalog and the card catalog in two department libraries at Ohio State University. Reasons for patron success and failure with the online catalog are outlined and discussed. Five data tables are included. (Author/JL)

Compares users' self-reported and observed usability problems within a Web-based information system. Participants were asked to complete a specific list of tasks within the system, after which they answered several questions regarding the system's usability. While, advanced users generally completed the tasks in less time than novices, the number…
