Digital libraries have become commodity in the current world of Internet. More and more information is produced, and more and more non-digital information is being rendered available. The new, more user friendly, community-oriented technologies used throughout the Internet are raising the bar of expectations. Digital libraries cannot stand still with their technologies; if not for the sake of handling...
The main motivation of this chapter was to gather existing requirements and solutions, and to present a generic architectural design of semantic digital libraries. This design is meant to answer a number of requirements, such as interoperability or ability to exchange resources and solutions, and set up the foundations for the best practices in the new domain of semantic digital libraries. We...
Our society produces more and more information every day and also tends to be increasingly dependent on it. Although some information is less/more costly to create or less/more relevant to our environment, some of it is defi nitely worth saving and may be of great value for next generations. Libraries (as well as similar institutions like archives) have the legal responsibility to safeguard long-term...
The first part of the chapter presents a synthesis of recent works in the domain of hyperbooks and introduces a general hyperbook model. In this model, a hyperbook is made of a knowledge structure, a set of informational fragment, links between the fragments and the knowledge structure, and a user interface specification. This specification is used to generate the actual reading interface which is...
Digital libraries offer several benefits for archiving unstructured or semi-structured data for long term use. Archival systems which follow a typical document access curve typically leverage online, near line, and offline storage mechanisms to efficiently store and retrieve documents. The nature of storage which is always online, such as large document conglomerations, such as Wikipedia or Google,...
Libraries are the tools we use to learn and to answer our questions. The quality of our work depends, among others, on the quality of the tools we use. Recent research in digital libraries is focused, on one hand on improving the infrastructure of the digital library management systems (DLMS), and on the other on improving the metadata models used to annotate collections of objects maintained by DLMS...
Through out this book we showed that Semantic Digital Libraries are no longer an abstract concept; we have presented both underlying technologies, examples of semantic digital libraries, and their applications. However, the bright future of this technology only begins, and we expect more and more genuine applications of semantic digital libraries to emerge. In this section we will spotlight...
As we look forward to the emergence of semantic digital libraries, it is good to consider their origins and sources in traditional digital libraries. A short examination of their definitions and applications will prove fruitful. It will provide a base for our later examination of the implications of adding semantic power to the digital library concept. This digital library (DL) was intended...
This chapter describes not so much what digital libraries are but what digital libraries with semantic support could and should be. It discusses the nature of Knowledge Organization Systems (KOS) and how KOS can support digital library users. It projects a vision for designers to make and for users to demand better digital libraries. What is a digital library? The term \Digital Library” (DL)...
This chapter presents ontologies and their role in the creation of the Semantic Web. Ontologies hold special interest, because they are very closely related to the way we understand the world. They provide common understanding, the very first step to successful communication. In following sections, we will present ontologies, how they are created and used. We will describe available tools for specifying...
The structural and syntactic web put in place in the early 90s is still much the same as what we use today: resources (web pages, files, etc.) connected by untyped hyperlinks. By untyped, we mean that there is no easy way for a computer to figure out what a link between two pages means { for example, on the W3C website, there are hundreds of links to the various organisations that are registered members...
The idea of bibliographic ontology comes from actual needs rather than today's common push to use the technology simply because it exists. The librarian community has always been enthusiastic to technical novelties to improve their work and make it more efficient. It is no different today. Managing bibliographic resources such as books was always a serious task. The goals are simple: to allow those...
The term \social network” was first mentioned in 1954 by J.A. Barnes [16]. The social network is a structure that consists of nodes; the nodes represent individual people or organizations. Such a structure depicts the ways in which people are connected through diverse social familiarities like acquaintance, friendship or close familiar bonds.
The initial research on semantic digital libraries [115] resulted in the design and implementation of JeromeDL [118]; current research on online social networking and information discovery delivered new sets of features that were implemented in JeromeDL. Eventually, this digital library has been redesigned to follow the architecture of a social semantic digital library (see Chapter “Architecture of Semantic Digital Libraries...
Service-oriented architectures, and the wider acceptance of decentralized peer-to-peer architectures enable the transition from integrated, centrally controlled systems to federated and dynamic configurable systems. The benefits for the individual service providers and users are robustness of the system, independence of central authorities and flexibility in the usage of services. This chapter...
