Generating collaborative systems for digital libraries: A model-driven approach
This is an open access article shared under a Creative Commons Attribution 3.0 Licence (http://creativecommons.org/licenses/by/3.0/). Copyright @ 2010 The Authors.The design and development of a digital library involves different stakeholders, such as: information architects, librarians, and domain experts, who need to agree on a common language to describe, discuss, and negotiate the services the library has to offer. To this end, high-level, language-neutral models have to be devised. Metamodeling techniques favor the definition of domainspecific visual languages through which stakeholders can share their views and directly manipulate representations of the domain entities. This paper describes CRADLE (Cooperative-Relational Approach to Digital Library Environments), a metamodel-based framework and visual language for the definition of notions and services related to the development of digital libraries. A collection of tools allows the automatic generation of several services, defined with the CRADLE visual language, and of the graphical user interfaces providing access to them for the final user. The effectiveness of the approach is illustrated by presenting digital libraries generated with CRADLE, while the CRADLE environment has been evaluated by using the cognitive dimensions framework
Ontological Approaches to Modelling Narrative
We outline a simple taxonomy of approaches to modelling narrative, explain how these might be realised ontologically, and describe our continuing work to apply these techniques to the problem of Memories for Life
Language-based multimedia information retrieval
This paper describes various methods and approaches for language-based multimedia information retrieval, which have been developed in the projects POP-EYE and OLIVE and which will be developed further in the MUMIS project. All of these project aim at supporting automated indexing of video material by use of human language technologies. Thus, in contrast to image or sound-based retrieval methods, where both the query language and the indexing methods build on non-linguistic data, these methods attempt to exploit advanced text retrieval technologies for the retrieval of non-textual material. While POP-EYE was building on subtitles or captions as the prime language key for disclosing video fragments, OLIVE is making use of speech recognition to automatically derive transcriptions of the sound tracks, generating time-coded linguistic elements which then serve as the basis for text-based retrieval functionality
A modular methodology for converting large, complex books into usable, accessible and standards-compliant ebooks
This report describes the methodology used for ebook creation for the Glasgow Digital Library (GDL), and provides detailed instructions on how the same methodology could be used elsewhere. The document includes a description and explanation of the processes for ebook creation followed by a tutorial
Design issues in the production of hyperâbooks and visualâbooks
This paper describes an ongoing research project in the area of electronic books. After a brief overview of the state of the art in this field, two new forms of electronic book are presented: hyperâbooks and visualâbooks. A flexible environment allows them to be produced in a semiâautomatic way starting from different sources: electronic texts (as input for hyperâbooks) and paper books (as input for visualâbooks). The translation process is driven by the philosophy of preserving the book metaphor in order to guarantee that electronic information is presented in a familiar way. Another important feature of our research is that hyperâbooks and visualâbooks are conceived not as isolated objects but as entities within an electronic library, which inherits most of the features of a paperâbased library but introduces a number of new properties resulting from its nonâphysical nature
Creative Archiving: A Case Study from the John Latham Archive
This article looks at the history of the archive profession and emphasises the perceived role of the archivist as the keeper of truth. It focuses on the recent developments in archival practice with the adoption of post-modern thinking and its implementation with open-access archives online. Following a discussion of that approach, it introduces the concept of creative archiving as an alternative approach to archival practice and continues with the presentation of a case study from the John Latham Archive. It concludes with a discussion of the main pros and cons of creative archiving
