Addressing the challenge of managing large-scale digital multimedia libraries

Traditional Digital Libraries require human editorial control over the lifecycles of digital objects contained therein. This imposes an inherent (human) overhead on the maintenance of these digital libraries, which becomes unwieldy once the number of important information units in the digital library becomes too large. A revised framework is needed for digital libraries that takes the onus off the editor and allows the digital library to directly control digital object lifecycles, by employing a set of transformation rules that operate directly on the digital objects themselves. In this paper we motivate and describe a revised digital library framework that utilises transformation rules to automatically optimise system resources. We evaluate this library in three scenarios and also outline how we could apply concepts from this revised framework to address other challenges for digital libraries and digital information access in general

Graphical Library for Educational Purposes

Práce se zabývá návrhem a vývojem grafické knihovny vhodné pro výuku programování na stedních školách a ukazuje použití této knihovny pro vizualizaci algoritmu na funkci sinus. Dále popisuje knihovny pro práci s grafickým výstupem a srovnává dobe známé multimediální knihovny.This thesis is focused on projecting and developing graphical library for educational purposes at high schools. And shows usage of this library for visualization of sinus function algorithm. Further describes graphical libraries and compares well known multimedia libraries.

Innovation Diffusion in Open Source Software: preliminary analysis of dependency changes in the gentoo portage package database

In this paper we make the case that software dependencies are a form of innovation adoption. We then test this on the time-evolution of the Gentoo package dependency graph. We find that the Bass model of innovation di usion ts the growth of the number of packages depending on a given library. Interestingly, we also nd that low-level packages have a primarily imitation driven adoption and multimedia libraries have primarily innovation driven growt

Preservation of Print and Non-Print Library Materials: A Case Study of the Kwame Nkrumah University of Science and Technology Main Library, Kumasi, Ghana

As a result of the emergence of information technology and the associated explosion of information almost all kinds of libraries now have some amount of print and non-print media as part of their stock. Preserving both print and non-print materials at the same time poses a great challenge. This write up therefore examines some of the problems encountered by libraries in their efforts to preserve information. The KNUST Main Library is used as a case study. These challenges as revealed by the study involved physical buildings, storage practices, pollution, light and biological agents, security of, as well as the handling of documents. The best practices to overcome these problems have also been reviewed. Collection surveys and observations were employed for the collection of data. The data gathered was analyzed graphically and descriptively. Findings from the analysis revealed that proper preservation is necessary because documents are susceptible to both inherent and environmental factors; materials in multimedia libraries contain information for entertainment, communication, research and socio-economic growth of a people; external factors such as chemical, biological, physical and disasters can also deteriorate multimedia materials. Finally, caution must be taken when blending the methods of preservation. Keywords: Preservation, Libraries, Print, Non-Print Journal of Science and Technology Vol. 28 (2) 2008: pp. 142-14

Advanced content-based semantic scene analysis and information retrieval: the SCHEMA project

The aim of the SCHEMA Network of Excellence is to bring together a critical mass of universities, research centers, industrial partners and end users, in order to design a reference system for content-based semantic scene analysis, interpretation and understanding. Relevant research areas include: content-based multimedia analysis and automatic annotation of semantic multimedia content, combined textual and multimedia information retrieval, semantic -web, MPEG-7 and MPEG-21 standards, user interfaces and human factors. In this paper, recent advances in content-based analysis, indexing and retrieval of digital media within the SCHEMA Network are presented. These advances will be integrated in the SCHEMA module-based, expandable reference system

Professional education for a digital world

Reviews developments in initial professional education for library and information work in relation to contemporary university library practice in the digital world, with particular reference to the impact of technology on content and delivery. Discusses connections between professional education and library practice, generalist versus specialist programmes and pathways, education for digital library environments and preparation for data management. Concludes that the current trend of locating library education programmes in schools with broader portfolios covering information technology and/or business offers valuable opportunities to extend module choice for students, particularly in relation to the technical skills and understanding needed for digital library environments
