Content-Based Indexing of Spatial Objects in Digital Libraries

Digital libraries maintain information lifecycles for the digital objects contained therein. Typically these information lifecycles stipulate that a digital object is deleted at the end of its lifecycle. We propose a transient framework for digital libraries in which suitable objects are transformed through a state transition lifecycle thereby reducing the need to ever delete the digital object from the digital library, Transience works for certain media types and we describe and positively evaluate a prototype deployment in the domain of security video.

This paper presents an approach of two-way data exchange between the citation content analysis, provided by the Cirtec project, and the big research digital library Socionet. Many papers in Socionet have citation relationships with other papers and also linkages with authors’ personal profiles and through them with other information objects. It allows making an enrichment of data for the citation content analysis by different additional information and, as well, linking results of such analysis with objects in a digital library, like papers, their authors, affiliation organizations, etc. We discuss what numeric and qualitative indicators can be built by citation content analysis based on the Cirtec open citation data. Since these indicators have IDs related with digital library objects, they can be integrated and visualized as computer-generated annotations to papers’ full texts in PDF.

The FRBR-model provided by the IFLA Study group on the Functional Requirements for Bibliographic Records addresses the need for a more thorough model of bibliographic information. This paper describes a solution for applying the FRBR model to existing bibliographic catalogues. This is accomplished by augmenting the catalogue with an externally stored map that contains relationships and entities according to the model. The core of the system is the Digital Library LinkService developed at the Norwegian University of Science and Technology - a flexible and general purpose link service developed to support the structuring of information objects in digital libraries. A client application is developed to visualize the map and to enable users to interact with the map by navigating along the available paths.

Adaptability and interoperability in the field of highly interactive web-based courseware

The authors discuss in this chapter the emergence of digital library environments of the modern world. The emerging field of digital libraries brings together participants from many existing areas of research. Currently, the field lacks a clear agenda independent of these other area. It is tempting for researchers to think that the field of digital libraries is a natural outgrowth of an already known field. From a database or information retrieval perspective, digital libraries may be seen as a form of federated databases. From a hypertext perspective, the field of digital libraries could seem like a particular application of hypertext technology. From a wide-area information service perspective, digital libraries could appear to be one use of the World Wide Web. From a library science perspective, digital libraries might be seen as continuing a trend toward library automation. New concepts and applications appear fast in the information world. Current exploitation of multimedia technology is changing our understanding of the interconnections of graphics, sound, and images, and the types of information they present. Thus, we need to understand both human psyche and available technologies in order to create and to interpret new expressions. The chapter highlights the benefits of digital information and how the libraries are helpful in enhancing the use of digital information. The chapter shows that libraries can provide Internet access, electronic contents, and training to the users. It explains the changing and changed attitude of information professionals in the present scenario.

PurposeThis paper aims to identify the critical success factors of the continued usage of digital library (DL) successful implementation from the perspective of users with organisation support factors as key antecedents.Design/methodology/approachBased on the extensive literature review, this study has constructed a conceptual framework based on organisational support perspectives and updated Delone and McLean’s information system success model. A pilot study was carried out on a sample of 105 respondents from military-context. A survey instrument including 22 measurement items was designed to identify the level of DL information system (IS) successful implementation practices in military context. Descriptive statistical analysis and reliability analysis were used to analyse the data with SPSS software.FindingsThe findings indicate that training and education, DL environment and communication support, continuation of usage intention, net benefits and user satisfaction are the critical success factors that play key role in ensuring the continued usage DL successful implementation in military context. The military-context DL needs to obtain critical success factors of DL practices implementation to sustain its continued usage, particularly for the active users of its members.Research limitations/implicationsThis study only considered the military personnel who have visited the five main military libraries. For practical implications, the development of instruments in this study may be valuable tools to evaluate DL in other DL settings in Malaysian context other than academic settings.Originality/valueThis study makes a new contribution to DL IS successful implementation practices in military context. This study also provides important information for decision-makers involved in DL IS successful implementation practices and provides useful reference for future researchers in this research area.

PurposeThe purpose of this paper is to explore useful Semantic Web technologies and ontology-based applications for digital libraries. It also investigates the perceptions of university librarians and academicians in Pakistan about Semantic Web technologies and their use in digital libraries.Design/methodology/approachAn exploratory research design based on Delphi research strategy was conducted to answer the research questions. Interviews were conducted with a purposive sample of 50 key informants including university librarians and academicians to explore their perceptions about Semantic Web technologies and their use in digital libraries. Thematic analysis of interview data was conducted to obtain results.FindingsThe results of this paper showed that DuraCloud, Semantic information mashup, OntoEdit and resource description framework (RDF) are the various Semantic Web applications which are useful for digital libraries to develop semantic relationships among digital contents and increase their accessibility in the web environment. Findings revealed that Semantic Web provides precise results and meets user information needs in an effective way.

We present an overview of our work and discuss future applications in biomedicine.

PurposeBlockchain technology is a distributed and decentralized public digital ledger, which is employed to save dynamic transaction data and static records across several computers so that each record could not be modified retroactively without the collusion of the network and alteration of all subsequent blocks. Recently, it has become immensely popular in digital resource sharing in different research areas such as healthcare, smart cities, cryptocurrency and libraries. Since the current eLibrary systems are vulnerable to issues such as unauthorized access, plagiarism, etc., there is a lack of access control system that can efficiently address these issues.Design/methodology/approachThe authors designed a conceptual model for evaluating the users' intention in the use of blockchain-based digital libraries, which can facilitate the resource organization and provide additional security to interactive processes between users. To conduct our survey, the authors devised and shared two versions, English and Chinese, among 298 participants. Moreover, 7 PhD students participated in the pre-testing of the questioner design. The authors analyzed the demographic data using the Jamovi software and SmartPLS in order to generate the path modeling.FindingsThis study revealed that blockchain technology adaption in eLibraries is essential for enhancing the quality of services, infrastructure and resources for libraries. The study’s results show that optimism, informativeness, perceived usefulness, perceived ease of use, attitude and intention to use blockchain technology for accessing digital resources in libraries.Originality/valueThis study contributes to the adoption of blockchain technology in the digital library. To the best of the authors’ knowledge, this work is the first empirical attempt to provide a new perspective of developing digital libraries based on security policies. This model shows the underpinning knowledge to manage digital resources, which can facilitate the design phases and enhance the management costs in eLibraries.

Digital libraries contains enormous digital resource, which has become important Web application architecture. The data of digital libraries are enormous, heterogeneous, dynamic and semi-structured. It is hotspot of digital libraries how to implement representation and query of the heterogeneous information and to provide intelligent services to users. Digital libraries aim at integration and share of information to provide users integrated retrieval services. The resources of digital libraries are often semi-structured data and have metadata to descript them. RDF can support representation and exchange of metadata, so it can be used as data representation specification in integrated information retrieval system of digital libraries. A demonstrative query language with predicate logic, query based on RDF and RDFS (Query-RB) was proposed in this paper. We sketch syntax and grammar of Query-RB with BNF. RB-Query has characteristic of semantic mapping, logic comprehending and combining of schema with data querying, so it is an effective query mechanism for IIR of digital libraries.

This paper reported an international survey of library, information science (LIS), computer science faculty and websites, regarding digital libraries courses and curriculum at our institutions. We concluded that few universities currently offer courses on digital libraries while many universities have not developed Digital Library (DL) courses, even they are aware of the need to develop curriculum in this growing area of research and practice. The major aim of the paper is to present results from a survey on the current state of digital library education (DLE) in academic institutions. Additionally we examine the rationale and orientation for digital library education. We suggest several models that have emerged in the teaching of DLE and in incorporation of relevant topics into various curricula.

The field of Scientometrics is concerned with the analysis of science and scientific research. As science advances, scientists around the world continue to produce large numbers of research articles, which provide the technological basis for worldwide collection, sharing, and dissemination of scientific discoveries. Research ideas are generally developed based on high quality citations. Understanding how research ideas emerge, evolve, or disappear as a topic, what is a good measure of quality of published works, what are the most promising areas of research, how authors connect and influence each other, who are the experts in a field, what works are similar, and who funds a particular research topic are some of the major foci of the rapidly emerging field of Scientometrics. Digital libraries and other databases that store research articles have become a medium for answering such questions. Citation analysis is used to mine large publication graphs in order to extract patterns in the data (e.g., citations per article) that can help measure the quality of a journal. Scientometrics, on the other hand, is used to mine graphs that link together multiple types of entities: authors, publications, conference venues, journals, institutions, etc., in order to assess the quality of science and answer complex questions such as those listed above. Tools such as maps of science that are built from digital libraries, allow different categories of users to satisfy various needs, e.g., help researchers to easily access research results, identify relevant funding opportunities, and find collaborators. Moreover, the recent developments in data mining, machine learning, natural language processing, and information retrieval makes it possible to transform the way we analyze research publications, funded proposals, patents, etc., on a web-wide scale. The workshop aims at bringing together researchers with diverse interdisciplinary backgrounds interested in mining large digital libraries and other relevant databases. The topics of interest include, but are not limited to:

In the public sector, the EU legislation requires preservation and opening of increasing amounts of heterogeneous digital information that should be utilized by citizens and businesses. While technologies such as big data analytics (BDA) have emerged, opening of digital archives and collections at a large scale is in its infancy. Opening archives and collections involve also particular requirements for recognizing and managing issues of privacy and digital rights. As well, ensuring the sustainability of the opened materials and economical appraisal of digital materials for preservation require robust digital preservation practices. We need to proceed beyond the state-of-the-art in opening digital archives and collections through the means of emerging big data analytics and validating a novel concept for analytics which then enables delivering of knowledge for citizens and the society. We set out an agenda for using BDA as our strategy for research and enquiry and for demonstrating the benefit of BDA for opening digital archives by civil servants and for citizens. That will – eventually - transform the preservation practices, and delivery and use opportunities of public digital archives. Our research agenda suggests a framework integrating four domains of inquiry, analytics-enhanced appraisal, analytics-prepared preservation, analytics-enhanced opening, and analytics-enhanced use, for utilizing the BDA technologies in the domain of digital archives and collections. The suggested framework and research agenda identifies initially particular BDA technologies to be utilized in each of the four domains, and contributes by highlighting a need for an integrated “public understanding of big data” in the domain of digital preservation.

Nowadays, the information access on the Web is a main problem in the computer science community. Any major advance in the field of information access on the Web requires the collaboration of different methodologies and research areas. In this paper, the concept of aggregation operator playing a role for information access on the Web is analyzed. We present some Web methodologies, as search engines, recommender systems, and Web quality evaluation models and analyze the way aggregation operators help toward the success of their activities. We also show an application of the aggregation operators in digital libraries. In particular, we introduce a Web information system to analyze the quality of digital libraries that implements an important panel of aggregation operators to obtain the quality assessments. © 2008 Wiley Periodicals, Inc.

Digital Libraries currently use several advanced information technologies to organize information and make it easy accessible to users. Current digital library trends to be dynamic digital library [1]. It is possible that business rules also can be approached for improving dynamic digital library. Business rules [2] are statements that define or contain some aspects of IT systems by providing a foundation for understanding how an IT system functions. At present, the need for automated business rules is becoming more essential because of the increasing usage of IT systems. However, it is not easy to extract business rules because they are written in a natural language structure and much of it is ignored. Therefore, one important question in this research area is how to automatically extract a business rule from a document? Based on this, information extraction (IE) [3] typically can be applied. Basically, IE is to transform text into information that is more readily analyzed. We believe that if the content of a document is decreased, the accuracy of rules extraction may be increased logically. With this assumption, if irrelevant information is filtered from the document, it is possible to easily extract business rules from the rest. Therefore, this research proposes a method based on probabilistic text classifier to extract synopsis information. It could be said that this work is the pre-processing of a business rules extraction methodology.
