Toward an integrated digital museum system – the Chi Nan experiences

The essential activities of a museum are multifaceted and include collection, preservation, research, exhibition, education, and entertainment. Hence, the march toward a full-fledged digital museum must evolve from the digital library concept with the addition of various interactive edutainment modules. In this paper, we describe various phases of the digital museum systems constructed by the National Chi Nan University, Taiwan, over the past few years. The design concepts and integration issues of essential digital museum modules are addressed. We have as our long-term goal the construction of an integrated digital museum that provides digital archives with user-friendly information access interfaces, intriguing virtual exhibitions, adaptive online courseware, and adaptive interactive games. A mechanism to facilitate the implementation of large-scale aesthetic exhibitions has been proposed. Our approach, the fine-grained modularization of aesthetic hypermedia presentations, concerns the balance between the complexity in the authoring process, the aesthetic qualities of final hypermedia presentations, and efforts at style template implementation. Moreover, various experiences and evaluations of content-based image retrieval, online courseware, and online interactive games will also be addressed. Future work toward an integrated digital museum system is proposed. Our digital museums can be accessed at http://dlm.ncnu.edu.tw.     

User-configurable OCR enhancement for online natural history archives

The creation of structured digital libraries from paper-based archives is an area of growing demand in many scientific and cultural fields, and is not satisfied either by off-the-shelf OCR or commercial form- processing systems. This paper describes and evaluates a configurable archive construction system, which integrates document image pre-processing and analysis with text post-processing tools and a standard OCR package to meet digital archiving requirements. The prototype system is currently being used in conjunction with the UK Natural History Museum to help convert more than 500,000 cards of Lepidoptera (Butterflies and Moths) and Coleoptera (Beetles) to searchable digital archives. Evaluation results covering different aspects of the system from card scanning to overall word recognition rates for different database fields are summarised for two datasets comprising over 5,000 cards selected from different parts of these archives. First-pass end-to-end word recognition rates of 70–90% are reported for key data fields, subject to availability of suitable electronic dictionaries. Further validation and correction is supported through web-editing of the online digital archive.

Trying it on for Size

ABSTRACT

Most colleges are continuing to see growth in their online education programs. Academic libraries are attempting to strike a balance between traditional library offerings and new online resources and services. Determining how to allocate funds is complicated by the fact that many students in online classes today live near enough campus to come to the library. Should libraries at institutions where most online students live near campus devote scarce resources to providing services such as online reference? One community college library is attempting to answer that question by testing online reference with Elluminate vClass in a limited way.

The Literacy Myth in the Digital Archive of Literacy Narratives

One of the central endeavors in contemporary literacy studies is to interrogate traditional definitions of literacy and deconstruct literacy myths. The Digital Archive of Literacy Narratives (DALN), a publicly accessible online repository for literacy narratives, implicates itself in this effort. This essay examines instantiations of the literacy myth within literacy narratives and the archive itself. An analysis of the content and design of the DALN offers insight into how the archive provides contributors both subversive and traditional frameworks for understanding literacy and literacy narratives. Then an examination of three digital literacy narratives in the DALN demonstrates how a combination of narrative analytics can be directed towards revealing constructions of the literacy myth in the telling and meaning-making of individual lives.

Video digital libraries: contributive and decentralised

Technology usage is changing rapidly and is becoming a more mobile, more social and more multimedia-based experience. This is especially true in the area of content creation where mobile social applications used by crowds of people are challenging traditional ways of creating and distributing content, especially for applications like news dissemination. Libraries have traditionally functioned as repositories where the information content of a society is analysed, curated, organised and stored, acting as a permanent record of what is to be remembered from a society. How can this function be achieved by present-day libraries attempting to cope with mobile, social, multimedia content who’s nature and utility of which change the type of information we wish to curate and store? This information is both dynamic and organic, posing challenges to the more fixed models of information in digital libraries. In this article we describe two digital library systems that archive video content from the sports domain, and which support user annotations and merging of diverse information sources in an integrated way. We report on analysis of the deployment of these two systems and highlight how they extend the traditional role of a (digital) library.     

Reinventing the archive in the age of digital reproduction: Walid Raad’s the Atlas Group*

Taking the Atlas Group (1989–2004) as a case study, this paper examines the aesthetic, political and technological possibilities of the digital archive. The Atlas Group is a fabricated digital archive founded by the Lebanese-American media artist Walid Raad, and it deals with the illusive history of the Lebanese Civil War (1975–1991). The digital takes an important role in Raad’s fictional archive, as it creates a tangible indexical fantasy that I would call the para-index. The para-index (an indexical sign without a referent) works to bring back Lebanon’s forgotten past by simulating / prefiguring its sensible form. Critic Rosalind Krauss calls this prefiguration of an aesthetic form within medium’s inherent technical property ‘the reinvention of the medium’ in this post-medium era. This paper aims to articulate how the Atlas Group reinvents the archive in this age of digital reproduction, and how this reinvention illuminate Lebanon’s unknown history.     

DOLPHIN: Digital Online Library Providing Human-Like InteractiveNavigation

In a digital library environment, we propose a novel support concept that is like a reference service in real libraries. Based on the concept, we have developed a prototype, called DOLPHIN, using a frame based knowledge base to support reference services in a digital library. DOLPHIN can guide the user to the appropriate service

A Review of “Technology and Literacy: 21st Century Library Programming for Children and Teens”

ABSTRACT

Given the endless volume of information available today, searchers are forced to satisfice when searching. The first satisfactory alternative is chosen over the best. Digital library search services, however, do not support satisficing users. There is no single, simple, comprehensive search service available to end-users to meet their need to gather information on alternatives from all information repositories accessible through a digital library. Federated search services bridge the gap between satisficing searchers and today's digital libraries.
