Metadata and Metaphors in Visual Interfaces to Digital Libraries

Author(s):  
Ali Shiri

This chapter introduces a new category of digital library user interfaces called metadata-enhanced visual interfaces. Drawing on the earlier information retrieval visual interfaces that have made use of thesauri, this chapter will review and analyze metadata-enhanced visual interfaces to digital libraries based on two key variables, namely metadata elements used for visualization purposes and visual metaphors incorporated into the user interfaces. The aim of this study is to inform the design of visual interfaces for digital libraries through bringing together issues that have roots in such communities as information retrieval, digital libraries, human-computer interaction, and metadata. The findings of this study provide design ideas and implications for digital library interface design in terms of the various metadata-based information search and retrieval features for visualization purposes.

The design and development of a digital library involves different stakeholders, such as: information architects, librarians, and domain experts, who need to agree on a common language to describe, discuss, and negotiate the services the library has to offer. To this end, high-level, language-neutral models have to be devised. Metamodeling techniques favor the definition of domainspecific visual languages through which stakeholders can share their views and directly manipulate representations of the domain entities. This paper describes CRADLE (Cooperative-Relational Approach to Digital Library Environments), a metamodel-based framework and visual language for the definition of notions and services related to the development of digital libraries. A collection of tools allows the automatic generation of several services, defined with the CRADLE visual language, and of the graphical user interfaces providing access to them for the final user. The effectiveness of the approach is illustrated by presenting digital libraries generated with CRADLE, while the CRADLE environment has been evaluated by using the cognitive dimensions framework.

Structural and semantic interoperability have been the focus of digital library research in the early 1990s. Many research works have been done on searching and retrieving objects across variations in protocols, formats, and disciplines. As the World Wide Web has become more popular in the last ten years, information is available in multiple languages in global digital libraries. Users are searching across the language boundary to identify the relevant information that may not be available in their own language. Cross-lingual semantic interoperability has become one of the focuses in digital library research in the late 1990s. In particular, research in cross-lingual information retrieval (CLIR) has been very active in recent conferences on information retrieval, digital libraries, knowledge management, and information systems. The major problem in CLIR is how to build the bridge between the representations of user queries and documents if they are of different languages.

Inter-country cooperation in any sector almost invariably begins with information exchange among the nations or groups involved. Briefly Describes international collaboration and networking in developing user-interfaces for selected Indian languages for an open source software - the GSDL (Greenstone Digital Library) software - for creating digital libraries of multilingual multimedia information resources, more particularly for the South Asia region. The steps in the formation of the related GSDL South Asia Network, the tasks assigned to the institutions in the SAARC countries, and the plan of work are mentioned. The role and contributions of the participating institutions and the organizations at the international level and in different countries is also briefly described. Further developmental work needed and problems to be solved as identified from the work done on user-interfaces in Indian languages are highlighted.

This chapter addresses the question of how the analysis of results retrieved from online bibliographic information systems changed over the last 32 years as digital libraries have evolved. It demonstrates that Digital Libraries of the future will enable knowledge discovery by providing direct access to the semantic content of documents through the implementation of text mining tools. To achieve this research with IR systems and text-mining tools, pipeline pilot (Bandy, et al., 2009), I2E (Vellay, 2009), and BioText will need to be conducted by experts in information retrieval not just subject scientific specialists.

Evaluation criteria and appropriate measures are critical to the success of digital library evaluation. The key problem is a lack of specific measures, especially from a heuristic perspective, corresponding to diverse dimensions and criteria. This study explored a variety of measures for digital library evaluation focusing on their appropriateness. It also compared the similarities and differences in perceptions of the appropriateness of digital library evaluation measures of two groups. Sixty-one participants were recruited representing scholars and academic digital librarians. The participants were instructed to fill in an in-depth survey consisting of 174 measures associated with 10 evaluation dimensions and 82 criteria. The findings of this study highlight the most appropriate measures in each dimension and show significant agreement in identifying appropriate measures by digital library scholars and librarians. Differences in the rating of the measures were found between the two groups in the dimensions of “interface design,” “system and technology,” “effects on users,” “administration,” “user engagement,” and “context.” The significance of this study lies not only in the integration of the perspectives on measures from both researchers and practitioners, but also in providing an inclusive list of measures to guide practitioners to effectively evaluate digital libraries in academic settings.

<p>The purpose of this paper is to report the findings of a systematic literature review carried out to investigate the applications and potential roles of thesaurus in digital libraries. It also describes the process of systematic literature review (SLR) followed to carry out this study. 321 unique publications from Library and Information Science Abstracts (LISA) and Scopus had been subjected to SLR, and 29 papers have been analysed. Various possible applications of thesaurus in digital libraries have been identified and described. Also different approaches followed by researchers in choice of the thesaurus have been identified. Search and browse functionalities offered by thesaurus to the users of digital libraries are described. The discussion presented in this paper can play as cues for the digital library administrators in decision making towards implementing thesaurus for enhanced information retrieval. This study would allow researchers of information retrieval systems, including that of digital libraries, to proceed from more informed standpoints. Also, the discussion can be used to evaluate and improve education in library and information science.</p>

A review of Druin, Allison. “What Children Can Teach Us: Developing Digital Libraries for Children with Children.” The Library Quarterly 75.1 (January 2005): 20-41. Objective – Through use of an interdisciplinary research team that included children, the study aimed to demonstrate that including children in the design of a digital library for children would result in some new approaches that would improve the site’s usability for the target user group. Design – Case study. Setting – The research was conducted at University of Maryland over a four-year period and involved an interdisciplinary research team of adult researchers from information studies, computer science, education, art, and psychology as well as seven children aged 7-11. Subjects – Seven children participated in the design team over two years; 153 children were observed and interviewed in the design phase; and the resulting new approaches were validated post-launch by analysis of International Children’s Digital Library (ICDL) (http://www.icdlbooks.org) users and usage patterns from November 2002-November 2003 (over 90,000 unique users and 19,000 optional questionnaire respondents). Method – The study included seven children in the design team for a digital library of international children’s books, which resulted in new approaches to collection development, cataloguing, and the search interface. In the design phase, research methods involving the seven children included brainstorming techniques, “cooperative inquiry”, low-tech prototyping; and lab use studies. The team also undertook observation and interviews of 153 children engaged in searching and selecting books from public library catalogues. In validating the new approaches that resulted from the design research, the team employed web log analysis, a voluntary online survey, and working with children in local schools to understand their use of ICDL. Main results – The inclusion of children’s viewpoints in the design stage of the ICDL had an impact in three areas: collection development, metadata, and interface design. For collection development, the research showed that kids were interested in books about children from other cultures and other times in history; in animals, both real and make-believe; in books that are sensitive to other cultures; and in books that are in good condition. For metadata, the research showed that children do not distinguish ‘fiction’ and ‘non-fiction’; look for ‘scary stuff’ or ‘gross stuff’; are often seeking books that make them feel a certain way; care about the look of book covers and may recall books by jacket colours; and use free vocabulary like ‘princesses’ and ‘jokes’. For interface design, the children’s involvement led to more search options (utilizing the new categories of metadata that were created), and customization options such as ability to choose different forms and colour palettes for book readers (e.g. the comic book reader, the spiral book reader). Web log and survey data, as well as lab tests, showed that the innovations resulting from the children’s design input were used. Of the over 90,000 unique users who visited the site in its first year, “genre” and “color” were statistically the fourth and fifth most popular search categories. In lab tests, girls used “color” twice as often as boys, and older boys preferred “genre” while younger children did not pay attention to that category. Conclusions – A first conclusion is that children’s input is vital to creating an online library that meets children’s information needs, tendencies and preferences. Also, seven design principles emerged: 1. Children’s input is invaluable and they should be involved in the design of their libraries. 2. Digital collections for children should consider works both contemporary and historical, and in different languages and representative of different cultures. 3. A variety of search interfaces are needed and it is particularly important to express categories with visual icons. 4. Additional metadata can be needed to reflect children’s views of relevant search criteria. 5. Interfaces should be customizable, such as providing various formats of reader that could themselves be customized in colour. 6. Tools should be suitable for use from the home and for collaborative use, such as use by a parent with a child. 7. Innovation requiring high bandwidth must be balanced with a low bandwidth version to assure broadest possible use. Lastly, the researchers concluded that more research is merited to assess the broader impact of digital libraries on children as searchers and readers.

Purpose The purpose of this study is to present an approach to evaluating the usability of digital libraries in terms of knowledge states within the information search process (ISP) by investigating the connections among components with which users interact, perceived usability and task stages. The China National Knowledge Infrastructure (CNKI), the most popular digital library in China, was chosen to be studied. Design/methodology/approach With the research framework, measurements were generated for perceived usability in task stages for efficiency, effectiveness and satisfaction. Two usability experiments and usability tests were administered to 22 subjects in two groups. Three information retrieval tasks were designed according to the characteristics of knowledge states within the ISP for each experiment. The transaction logs were captured and the experimental results were recorded. The users completed a pre-search questionnaire and post-search questionnaire, and interviews were conducted. Findings The study showed that both interactions on components of the digital library and usability scores differed with sequential tasks characterized by knowledge states within the ISP; new usability problems relating to the CNKI were found based on the empirical results. Originality/value Many studies on the usability evaluation of digital libraries focused on the outcome rather than on the ISP. This study proposed an effective approach to usability evaluation based on users’ knowledge states within the ISP.
