“…Todd and Benbasat (1992) and Lim et al (1996) argued that the way information is presented on the computer screen is also capable of influencing the user's information search strategies and performance. In other related studies, Hu et al (1999) and Liu et al (2000) proposed that graphical user interfaces were found to enable richer interaction with users in both retrieval systems and digital libraries. However, in the recent study of Goon (2004) it was found that screen design was not a determinant of ease of use.…”

A good understanding of user tasks is the foundation of designing useful visualizations. Rao et al. defined several specific user tasks of digital libraries and illustrated some existing information-visualization techniques that can be used to enhance these tasks, such as TileBar, Cone Tree, and Document Lens.1 The tasks were browsing subsets of sources iteratively, viewing context-of-query match, visualizing passages within documents, rendering sources and results, reflecting time costs of interaction, managing multiple-search processes, integrating multiple search and browsing techniques, and visualizing large information sets. Moreover, Zaphiris et al. generalized these tasks into three essential ones: searching, navigation, and browsing.2 Indeed, most information-visualization projects for digital libraries have emphasized these three tasks.In terms of searching, Shneiderman et al. proposed the use of a two-dimensional display with continuous variables to view several thousand search results simultaneously.3 This visualization included two strategies: two-dimensional visualizations, and browsers for hierarchical data sets (implemented by using categorical and hierarchical axes). In combination with a grid display, this visualization let users see an overview by colorcoded dots or bar charts arranged on a grid and organized by familiar labeled categories. Users could probe further by zooming in on desired categories or switching to another hierarchical variable. A language-independent document-classification system, completed by Liu et al., provided a search aid in a digital-library environment and helped users analyze the search query results visually. 4 This system used a vector model to calculate the similarities between documents and a Java applet to display the classification to the user.In terms of navigation, there are also a variety of information-visualization applications. The previous example of two-dimensional display developed by Shniederman et al. also contained navigation functions. 5Another example is Hascoet's map interface applied to a digital library. 6 This prototype was associated with summary views in the form of navigation trees and neighbor trees that showed documents related to one focus document. The user interface was composed of maps automatically generated based on the characteristics of documents retrieved and a default configuration. Users could also modify the configuration of maps and edit maps (classical operations such as cut, paste, move, delete, save and load a view, and expand a view).As for browsing, the use of dynamic queries is a technique that has been employed for some time. Ahlberg and Shneiderman's (1994) FilmFinder is an early example. 7Users can move several sliders to select query parameters, and the search results change with the movement of the sliders. This tool can help users browse movie records more easily and cognitively. Another technique is Query Previews, proposed by Doan et al. 8 Query Previews allows users to rapidly gain an understanding of the cont...

“…There are efforts underway to enhance existing digital libraries through graphical browsing of results [14], browsing by virtual shelves [21], automatic thesaurus generation techniques to create graphs of domain specific concepts [5], and allowing a searcher to pose queries to one viewpoint and then change to another viewpoint while retaining a sense of context [9]. As yet we are unaware of any attempt to add a community meta-data dimension to a digital library.…”

This paper presents a differential usage study of a web-based resource database that provides both search and associative browsing functionality. The associative browsing is based on emergent meta-data: meta-data that is derived from the terms that users associate with resources they have contributed to the system. We argue that this approach provides a low cognitive load information seeking mechanism, and can also reduce the effort required by the user to enter meta-data when contributing resources. In this paper we concentrate on a three-month study of student librarians using the system, with analysis of their activities and other data collected by questionnaire. The results suggest that associative browsing was at least as popular as search, and that providing perspectives on emerging meta-data during the contribution process may have helped the community self-organize a vocabulary. .
