This is What I’m Doing and Why: Reflections on a Think-Aloud Study of Digital Library Users. Information Behaviour (Short Paper)
Stephann Makri, Ann Blandford and Anna Cox
Abstract. Many user-centred studies of digital libraries include a think-aloud element . where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using digital libraries to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the system(s) used or understanding aspects of users’ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on their methodologies. In this paper, we discuss and reflect on the decisions made when planning and conducting a think-aloud study of lawyers. interactive information behaviour. Our discussion is framed by Blandford et al.’s PRET A Rapporter (‘ready to report’) framework . a framework that can be used to plan, conduct and describe user-centred studies of digital library use from an information work perspective.
Customizing Science Instruction with Educational Digital Libraries (Short Paper)
Abstract. The Curriculum Customization Service enables science educators to customize their instruction with interactive digital library resources. Preliminary results from a field trial with 124 middle and high school teachers suggest that the Service offers a promising model for embedding educational digital libraries into teaching practices and for supporting teachers to integrate customizing into their curriculum planning.
Impact and Prospect of Social Bookmarks for Bibliographic Information Retrieval (Short Paper)
Kazuhiro Seki, Huawai Qin and Kuniaki Uehara
Abstract. This paper presents our ongoing study of the current/future impact of social bookmarks (or social tags) on information retrieval (IR). Our main research question asked in the present work is “How are social tags compared with conventional, yet reliable manual indexing from the viewpoint of IR performance?”. To answer the question, we look at the biomedical literature and begin with examining basic statistics of social tags from CiteULike in comparison with Medical Subject Headings (MeSH) annotated in the Medline bibliographic database. Then, using the data, we conduct various experiments in an IR setting, which reveals that social tags work complementarily with MeSH and that retrieval performance would improve as the coverage of CiteULike grows.
Merging Metadata: A Sociotechnical Study of Crosswalking and Interoperability (Short Paper)
Abstract. Digital library interoperability relies on the use of a common metadata format. However, implementing a common metadata format among multiple digital libraries is not always a straightforward exercise. This paper presents a case study of the metadata and interoperability issues that arose during the merger of two digital libraries, the Internet Public Library and the Internet Librarian.s Index. As part of the merger, each library.s metadata was crosswalked to Dublin Core. These crosswalks required considerable work, partly because the metadata for each library had been shaped in complex ways over time by local institutional factors. Not all of these differences in the metadata were obvious, and some were ignored for some time, negatively impacting the crosswalk process. A sociotechnical analysis that suggests that local metadata knowledge can be complex in nature and hard to crosswalk, and also that this complexity can be hard to understand to those working in the libraries themselves. Some implications of this finding for digital library interoperability are discussed.
Emulation Based Services in Digital Preservation (Short Paper)
Klaus Rechert, Dirk von Suchodoletz and Randolph Welte
Abstract. The creation of most digital objects occurs solely in interactive graphical user interfaces which were available at the particular time period. Archiving and preservation organizations are posed with large amounts of such objects of various types. At some point they will need to automatically process these to make them available to their users or convert them to a commonly used format. A substantial problem is to provide a wide range of different users with access to ancient environments and to allow using the original environment for a given object. We propose an abstract architecture for emulation services in digital preservation to provide remote user interfaces to emulation over computer networks without the need to install additional software components. Furthermore, we describe how these ideas can be integrated in a framework of web services for common preservation tasks like viewing or migrating digital objects.
