A study of the information needs of the users of a folk music library and the implications for the design of a digital library system

A qualitative study of user information needs is reported, based on a purposive sample of users and potential users of the Vaughan Williams Memorial Library, a small specialist folk music library in North London. The study set out to establish what the user’s (both existing and potential) information needs are, so that the library’s online service may take them into account with its design. The information needs framework proposed by Nicholas (2000) is used as an analytical tool to achieve this end. The demographics of the users were examined in order to establish four user groups: Performer, Academic, Professional and Enthusiast. Important information needs were found to be based on social interaction, and key resources of the library were its staff, the concentration of the collection and the library’s social nature. A collection of broad design requirements are proposed based on the analysis and this study also provided some insights into the issue of musical relevance, which are discussed

Digital Music Libraries: Librarian Perspectives and the Challenges Ahead

This paper reports the results of a survey targeting current members of the Canadian Association of Music Libraries, Archives and Documentation Centres (CAML) that investigated the extent to which the current designs and structures of digital music libraries meet the needs of librarians in collecting, preserving, organizing, and disseminating diverse types of music documents. The challenges and barriers experienced in hosting digital collections are discussed. The gap between the current and ideal functionalities, as well as the future possibilities, are explored.

An examination of automatic video retrieval technology on access to the contents of an historical video archive

Purpose – This paper aims to provide an initial understanding of the constraints that historical video collections pose to video retrieval technology and the potential that online access offers to both archive and users. Design/methodology/approach – A small and unique collection of videos on customs and folklore was used as a case study. Multiple methods were employed to investigate the effectiveness of technology and the modality of user access. Automatic keyframe extraction was tested on the visual content while the audio stream was used for automatic classification of speech and music clips. The user access (search vs browse) was assessed in a controlled user evaluation. A focus group and a survey provided insight on the actual use of the analogue archive. The results of these multiple studies were then compared and integrated (triangulation). Findings – The amateur material challenged automatic techniques for video and audio indexing, thus suggesting that the technology must be tested against the material before deciding on a digitisation strategy. Two user interaction modalities, browsing vs searching, were tested in a user evaluation. Results show users preferred searching, but browsing becomes essential when the search engine fails in matching query and indexed words. Browsing was also valued for serendipitous discovery; however the organisation of the archive was judged cryptic and therefore of limited use. This indicates that the categorisation of an online archive should be thought of in terms of users who might not understand the current classification. The focus group and the survey showed clearly the advantage of online access even when the quality of the video surrogate is poor. The evidence gathered suggests that the creation of a digital version of a video archive requires a rethinking of the collection in terms of the new medium: a new archive should be specially designed to exploit the potential that the digital medium offers. Similarly, users' needs have to be considered before designing the digital library interface, as needs are likely to be different from those imagined. Originality/value – This paper is the first attempt to understand the advantages offered and limitations held by video retrieval technology for small video archives like those often found in special collections

Using fuzzy logic to handle the semantic descriptions of music in a content-based retrieval system

This paper explores the potential use of fuzzy logic for semantic music recommendation. We show that a set of affective/emotive, structural and kinaesthetic descriptors can be used to formulate a query which allows the retrieval of intended music. A semantic music recommendation system was built, based on an elaborate study of potential users and an analysis of the semantic descriptors that best characterize the user’s understanding of music. Significant relationships between expressive and structural semantic descriptions of music were found. Fuzzy logic was then applied to handle the quality ratings associated with the semantic descriptions. A working semantic music recommendation system was tested and evaluated. Real-world testing revealed high user satisfaction

Using fuzzy logic to handle the users' semantic descriptions in a music retrieval system

This paper provides an investigation of the potential application of fuzzy logic to semantic music recommendation. We show that a set of affective/emotive, structural and kinaesthetic descriptors can be used to formulate a query which allows the retrieval of intended music. A semantic music recommendation system was built, based on an elaborate study of potential users of music information retrieval systems. In this study analysis was made of the descriptors that best characterize the user's understanding of music. Significant relationships between expressive and structural descriptions of music were found. A straightforward fuzzy logic methodology was then applied to handle the quality ratings associated with the descriptions. Rigorous real-world testing of the semantic music recommendation system revealed high user satisfaction

Z39.50 broadcast searching and Z-server response times: perspectives from CC-interop

This paper begins by briefly outlining the evolution of Z39.50 and the current trends, including the work of the JISC CC-interop project. The research crux of the paper focuses on an investigation conducted with respect to testing Z39.50 server (Z-server) response times in a broadcast (parallel) searching environment. Customised software was configured to broadcast a search to all test Z-servers once an hour, for eleven weeks. The results were logged for analysis. Most Z-servers responded rapidly. 'Network congestion' and local OPAC usage were not found to significantly influence Z-server performance. Response time issues encountered by implementers may be the result of non-response by the Z-server and how Z-client software deals with this. The influence of 'quick and dirty' Z39.50 implementations is also identified as a potential cause of slow broadcast searching. The paper indicates various areas for further research, including setting shorter time-outs and greater end-user behavioural research to ascertain user requirements in this area. The influence more complex searches, such as Boolean, have on response times and suboptimal Z39.50 implementations are also emphasised for further study. This paper informs the LIS research community and has practical implications for those establishing Z39.50 based distributed systems, as well as those in the Web Services community. The paper challenges popular LIS opinion that Z39.50 is inherently sluggish and thus unsuitable for the demands of the modern user

DOCUMENTATION AND DISSEMINATION OF INDIGENOUS KNOWLEDGE BY LIBRARY PERSONNEL IN SELECTED RESEARCH INSTITUTES IN NIGERIA

Indigenous Knowledge (IK) and practices are usually unwritten; relying on oral transmission and human memory. As a result, this study investigated the documentation and dissemination of Indigenous Knowledge by library personnel at five selected research institutes in Ibadan, Nigeria. Using the descriptive survey design, six (6) questions raised to achieve the stated objectives. Structured questionnaire and interview were used for data collection. The population comprised of professionals and para-professionals library staff at Nigeria Institute of Social and Economic Research (NISER), Institute of African Studies (IFRA), Forestry Research Institute of Nigeria (FRIN), Cocoa Research Institute of Nigeria (CRIN), and International Institute of Tropical Agriculture (IITA). Purposive sampling method was used to select samples considering the resources to be expended and time involved for the study. Data were analyzed with the use of Statistical Package for Social Science (SPSS 16) while simple frequency count of percentage distribution was used to present the results of findings in table. Some of the findings of the study revealed that Indigenous Knowledge documented at the research institutes were on: Agriculture; kingship system in different towns; traditional medicine; general traditional culture; as well as traditional politics and governance. In addition, Indigenous Knowledge practices were documented with recordings and visual documentation among other methods, and these are being done by all the library personnel. Meanwhile, Indigenous Knowledge practices are being disseminated through: video, library website, print media, direct mail, public lectures, exhibitions and displays, and exchange. Certain recommendations were made based on the findings of this study

Vernacular Music Material Culture in Space and Time

Few musical instruments are more closely tied or hold greater significance to American history than the banjo. From its West African roots, to its birth in the seventeenth century Caribbean, and through its meteoric rise in nineteenth century American popular culture, the banjo is an iconic instrument whose impact is woven into the cultural fabric of the American experience. As scholars, researchers, and enthusiasts continue to discover new information about the early banjo, there is no collective location to maintain, interact with, and collectively analyze this important data. The proposed Banjo Sightings Database Project (BSD) will combine rare and widely-dispersed primary source material (circa 1650-1870) with appropriate and innovative technological applications, resulting in a system that not only catalogs information about the early banjo, but also establishes an interactive, peer-reviewed knowledge management system, allowing users to explore the early banjo
