Visual collaging of music in a digital library

This article explores the role visual browsing can play within a digital music library. The context to the work is provided through a review of related techniques drawn from the fields of digital libraries and human computer interaction. Implemented within the open source digital library toolkit Greenstone, a prototype system is described that combines images located through textual metadata with a visualisation technique known as collaging to provide a leisurely, undirected interaction with a music collection. Emphasis in the article is given to the augmentations of the basic technique to work in the musical domain

A workflow for document level interoperability

This article describes a software environment called the Exchange Center that helps digital librarians manage the workflow of sourcing documents and metadata from various repositories. The software is built on Greenstone but does not require its use as the final digital library server. After describing the software architecture we provide two scenarios of its use: a private library of recipes, which ultimately involves collaboration with other cooks; and a digital library that aggregates the collections of various host institutions that use different repository software

Power to the people: end-user building of digital library collections

Naturally, digital library systems focus principally on the reader: th e consumer of the material that constitutes the library. In contrast, this paper describes an interface that makes it easy for people to build their own library collections. Collections may be built and served locally from the user's own web server, or (given appropriate permissions) remotely on a shared digital library host. End users can easily build new collections styled after existing ones from material on the Web or from their local files-or both, and collections can be updated and new ones brought on-line at any time. The interface, which is intended for non-professional end users, is modeled after widely used commercial software installation packages. Lest one quail at the prospect of end users building their own collections on a shared system, we also describe an interface for the administrative user who is responsible for maintaining a digital library installation

The Development and Usage of the Greenstone Digital Library Software

The Greenstone software has helped spread the practical impact of digital library technology throughout the world-particularly in developing countries. This article reviews the project’s origins, usage, and the development of support mechanisms for Greenstone users. We begin with a brief summary of salient aspects of this open source software package and its user population. Next we describe how its international, humanitarian focus arose. We then review the special requirements imposed by the conditions that prevail in developing courtiers. Finally we discuss efforts to establish regional support organizations for Greenstone in India and Africa

Institutional Repositories: Features, Architecture, Design and Implementation Technologies

Europe is the leading continent in terms of active adoption and use of Digital Libraries – particularly Institutional Repositories (IRs). Africa has not done poorly in this area with a steady increase from 19 repositories in 2008 to 46 in January, 2011 but there is need to raise awareness and channel efforts towards making IRs easily accessible to Africans through ubiquitous channels such as hand-helds and mobile devices. This paper reviews the features, architecture, design and implementation technologies of IRs. In addition, it highlights viable research areas that can be pursued by African researchers in the field of Digital Libraries. It also encourages research efforts to focus on areas that will be beneficial to Africa

An Interactive User Management System for Multilingual Documents: A case study of the Pei Jones collection

Can general purpose DL software architecture be designed to provide a flexible environment that supports both the management and end-user roles through a single unified web interface? In particular we take the collected correspondence of the Māori scholar Dr. Pei Jones and undertake case study of how this approach can be applied in a practical way

A location-based audio book reader

The ability to display text on mobile devices has been progressively improved during the last decade with the growth in use of mobile devices. Recently, the e-book reader has been incorporated into travel tourism. In this project we design, implement and evaluate a location-based mobile e-book reader that provides users with both text and audio information. This project has two goals. The first goal is to build a rich location-based travel information provider system as a standalone mobile application without using web browsing functions. The second goal is to provide a communication between the mobile application and a digital library of e-book collections. Experimental results show that the mobile application, during elected events, has provided a special e-book reading experience to participants. The majority of participants liked the system especially with regards to interface design and functionality. Over half the participants felt the location-based audio e-book reader system was usable and interesting while traveling

Automatic text summarization in digital libraries

xiii, 142 leaves ; 28 cm.A digital library is a collection of services and information objects for storing, accessing, and retrieving digital objects. Automatic text summarization presents salient information in a condensed form suitable for user needs. This thesis amalgamates digital libraries and automatic text summarization by extending the Greenstone Digital Library software suite to include the University of Lethbridge Summarizer. The tool generates summaries, nouns, and non phrases for use as metadata for searching and browsing digital collections. Digital collections of newspapers, PDFs, and eBooks were created with summary metadata. PDF documents were processed the fastest at 1.8 MB/hr, followed by the newspapers at 1.3 MB/hr, with eBooks being the slowest at 0.9 MV/hr. Qualitative analysis on four genres: newspaper, M.Sc. thesis, novel, and poetry, revealed narrative newspapers were most suitable for automatically generated summarization. The other genres suffered from incoherence and information loss. Overall, summaries for digital collections are suitable when used with newspaper documents and unsuitable for other genres
