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

Interface, March 2002

Greetings and welcome to the revised and renewed Interface. Please share your copy with others in the information and library science community, for many items will be of interest beyond our own School\u27s alumni. In this quarter\u27s column, I am inviting you to participate in two exciting events in the life of our School: SIS Accreditation Activities and the 30th Anniversary Celebration & $30,000 for 30 Years Campaign

The KO roots of Taylor’s Value-Added Model

The model developed by Bob Taylor for his book Value-Added Processes in Information Systems (1986) has been highly influential in the field of library and information science. Yet despite its impact on the broader field, the potential of the Value-Added Model has gone largely unexplored by knowledge organization researchers. Unraveling the history behind Taylor’s development of the model highlights the significant role played by professional indexers. The Value-Added Model is thus reexamined for its potential as a flexible framework for evaluating knowledge organization systems

Race: the difference that makes a difference

During the last two decades, critical enquiry into the nature of race has begun to enter the philosophical mainstream. The same period has also witnessed the emergence of an increasingly visible discourse about the nature of information within a diverse range of popular and academic settings. What is yet to emerge, however, is engagement at the interface of the two disciplines – critical race theory and the philosophy of information. In this paper, I shall attempt to contribute towards the emergence of such a field of enquiry by using a reflexive hermeneutic (or interpretative) approach to analyze the concept of race from an information-theoretical perspective, while reflexively analyzing the concept of information from a critical race-theoretical perspective. In order to facilitate a more concrete enquiry, the concept of information formulated by cyberneticist Gregory Bateson and the concept of race formulated by philosopher Charles W Mills will be placed at the centre of analysis. Crucially, both concepts can be shown to have a connection to the critical philosophy of Immanuel Kant, thereby justifying their selection as topics of examination on critical reflexive hermeneutic grounds

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

Working with activity theory : context, technology, and information behavior

Over the last 7 years, the AIMTech Research Group in the University of Leeds has used cultural‐historical activity theory (CHAT) to inform a range of research activities in the fields of information behavior and information systems. In this article, we identify certain openings and theoretical challenges in the field of information behavior, which sparked our initial interest in CHAT: context, technology, and the link between practice and policy. We demonstrate the relevance of CHAT in studying information behavior and addressing the identified openings and argue that by providing a framework and hierarchy of activity‐action‐operation and semantic tools, CHAT is able to overcome many of the uncertainties concerning information behavior research. In particular, CHAT provides researchers a theoretical lens to account for context and activity mediation and, by doing so, can increase the significance of information behavior research to practice. In undertaking this endeavour, we have relied on literature from the fields of information science and others where CHAT is employed. We provide a detailed description of how CHAT may be applied to information behavior and account for the concepts we see as relevant to its study

Visual Materials and Online Access: Issues Concerning Content Representation

A more holistic view of the current situation surrounding image access is needed. Much of the research into content representation of images appears not to recognize a number of basic issues underlying the difficulty in achieving satisfactory results in this area. Beyond the lack of institutional support typically seen in collections of printed matter, visual materials have not received the level of intellectual research needed to develop the theoretical bases behind their access. Several basic issues stand out as being critical obstacles to providing access to visual materials, including a lack of agreement concerning types of information needed, a lack of a universally applied schema, a lack of standard vocabularies, subect indexing, or user studies. In order to provide a general overview of the topic of images and content representation, this article will investigate each of these problematic topics individually
