Lazarinis, Fotis – Program: Electronic Library and Information Systems, 2010
Purpose: Searching for information and viewing visual representations of products in e-organisations is a common activity of the e-visitors to these organisations. For example, in e-museums, users are shown images or other visual information of the existing objects. The aim of this paper is to present a tool which supports the effective searching…

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…

Rauber, Andreas; Muller-Kogler, Alexander – 2001
With the number and types of documents in digital library systems increasing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system incorporates automatic structural analysis and representation. Yet, genre information…

Frost, C. Olivia – Proceedings of the ASIST Annual Meeting, 2001
Reports the preliminary findings of a research project that investigated users' mental models in the course of an image search. Generalist users searched a database of 1500 earth and space science images using a system that provided for both textual and content-based retrieval modalities. Factors such as ease of use and satisfaction with the…

Lawrence, Barbara – 1978
The use of computers in retrieving bibliographic chemical information is traced through the SDI, batch, and online modes, and related changes are noted in such areas as data base availability, cost, software, and amount of user control. The impact of these changes on both the quality and quantity of chemical information use is discussed, as well…

Goodrum, Abby A. – Journal of the American Society for Information Science and Technology, 2001
Four types of video surrogates were compared under two tasks. Multidimensional scaling was used to map dimensional dispersions of users' judgments of similarity between videos and surrogates. Congruence between these maps was used to evaluate representativeness of each surrogate type. Congruence was greater for image-based than for text-based…

White, Howard; Lin, Xia; Buzydlowski, Jan – Proceedings of the ASIST Annual Meeting, 2001
Two major research streams of information science, bibliometric mapping and document retrieval combined in the literature visualization movement with the implementation of VIRI (visual information retrieval interface). The capability now exists to quickly map the citation images of thousands of persons through AuthorLink, to map displays of…

Rorvig, Mark; Fitzpatrick, Steven – Journal of the American Society for Information Science, 2000
The method described permits visual analysis of information retrieval (IR) experiment results in classic control and treatment group protocols. It is an additional analysis technique for the evaluation of IR procedures that may be conducted within the rich terrain of human visual acuity, supported by two well-known statistical measures. (Contains…

Ben-Arie, Jezekiel; Pandit, Purvin; Rajaram, ShyamSundar – 2001
This paper is focused on a central aspect in the design of a planned digital library for human movement, i.e. on the aspect of representation and recognition of human activity from video data. The method of representation is important since it has a major impact on the design of all the other building blocks of the system such as the user…

Hastings, Samantha K. – Library Trends, 1999
Suggests that preliminary findings from research on intellectual access to digital images indicate a need for improved browsing tools, image manipulation software, feedback mechanisms, and query analysis. Discusses problems of image retrieval identified in current research, reports on an evaluation project in process, and proposes a framework for…

Srihari, Rohini K.; Zhang, Zhongfei – Library Trends, 1999
Finding information on the Web without encountering numerous false positives poses a challenge to multimedia information retrieval systems (MMIR). This research focuses on improving precision and recall in an MMIR system by interactively combining text processing with image processing in both the indexing and retrieval phases. A picture search…

Rasmussen, Edie M. – Annual Review of Information Science and Technology (ARIST), 1997
Focuses on access to digital image collections by means of manual and automatic indexing. Contains six sections: (1) Studies of Image Systems and their Use; (2) Approaches to Indexing Images; (3) Image Attributes; (4) Concept-Based Indexing; (5) Content-Based Indexing; and (6) Browsing in Image Retrieval. Contains 105 references. (AEF)

Heidorn, P. Bryan – Proceedings of the ASIS Annual Meeting, 1999
Examines the vocabulary and communication constructs that are used by novices and domain experts to describe objects in an object identification task. Results suggest that indexing and retrieval systems should provide semantic level similarity mechanisms to allow for whole-object as well as part-wise visual analogy. The systems should also provide…
