Abstract

Proposes how a global Hypermedia system could evolve from the “Hyper‐G” system, currently being developed at Graz University. Overviews the development of Internet from post‐war visionary speculation to present. Explains some limitations of the current architecture (World Wide Web, Gopher, WAIS). Presents in detail the architecture of a massively distributed hypermedia system. Explains how the proposed system would be much faster, overcoming such problems as documents being oriented by location rather than by subject. Suggests possible applications.

Abstract

Purpose

Research data publishing is today widely regarded as crucial for reproducibility, proper assessment of scientific results, and as a way for researchers to get proper credit for sharing their data. However, several challenges need to be solved to fully realize its potential, one of them being the development of a global standard for links between research data and literature. Current linking solutions are mostly based on bilateral, ad hoc agreements between publishers and data centers. These operate in silos so that content cannot be readily combined to deliver a network graph connecting research data and literature in a comprehensive and reliable way. The Research Data Alliance (RDA) Publishing Data Services Working Group (PDS-WG) aims to address this issue of fragmentation by bringing together different stakeholders to agree on a common infrastructure for sharing links between datasets and literature. The paper aims to discuss these issues.

Design/methodology/approach

This paper presents the synergic effort of the RDA PDS-WG and the OpenAIRE infrastructure toward enabling a common infrastructure for exchanging data-literature links by realizing and operating the Data-Literature Interlinking (DLI) Service. The DLI Service populates and provides access to a graph of data set-literature links (at the time of writing close to five million, and growing) collected from a variety of major data centers, publishers, and research organizations.

Findings

To achieve its objectives, the Service proposes an interoperable exchange data model and format, based on which it collects and publishes links, thereby offering the opportunity to validate such common approach on real-case scenarios, with real providers and consumers. Feedback of these actors will drive continuous refinement of the both data model and exchange format, supporting the further development of the Service to become an essential part of a universal, open, cross-platform, cross-discipline solution for collecting, and sharing data set-literature links.

Originality/value

This realization of the DLI Service is the first technical, cross-community, and collaborative effort in the direction of establishing a common infrastructure for facilitating the exchange of data set-literature links. As a result of its operation and underlying community effort, a new activity, name Scholix, has been initiated involving the technological level stakeholders such as DataCite and CrossRef.

Abstract

Purpose

The purpose of this paper is to apply link prediction to community mining and to clarify the role of link prediction in improving the performance of social network analysis.

Design/methodology/approach

In this study, the 2009 version of Enron e-mail data set provided by Carnegie Mellon University was selected as the research object first, and bibliometric analysis method and citation analysis method were adopted to compare the differences between various studies. Second, based on the impact of various interpersonal relationships, the link model was adopted to analyze the relationship among people. Finally, the factorization of the matrix was further adopted to obtain the characteristics of the research object, so as to predict the unknown relationship.

Findings

The experimental results show that the prediction results obtained by considering multiple relationships are more accurate than those obtained by considering only one relationship.

Research limitations/implications

Due to the limited number of objects in the data set, the link prediction method has not been tested on the large-scale data set, and the validity and correctness of the method need to be further verified with larger data. In addition, the research on algorithm complexity and algorithm optimization, including the storage of sparse matrix, also need to be further studied. At the same time, in the case of extremely sparse data, the accuracy of the link prediction method will decline a lot, and further research and discussion should be carried out on the sparse data.

Practical implications

The focus of this research is on link prediction in social network analysis. The traditional prediction model is based on a certain relationship between the objects to predict and analyze, but in real life, the relationship between people is diverse, and different relationships are interactive. Therefore, in this study, the graph model is used to express different kinds of relations, and the influence between different kinds of relations is considered in the actual prediction process. Finally, experiments on real data sets prove the effectiveness and accuracy of this method. In addition, link prediction, as an important part of social network analysis, is also of great significance for other applications of social network analysis. This study attempts to prove that link prediction is helpful to the improvement of performance analysis of social network by applying link prediction to community mining.

Originality/value

This study adopts a variety of methods, such as link prediction, data mining, literature analysis and citation analysis. The research direction is relatively new, and the experimental results obtained have a certain degree of credibility, which is of certain reference value for the following related research.

Abstract

In this paper we present a model‐based approach for the development of physical hypermedia applications, i.e. those mobile (Web) applications in which physical and digital objects are related and explored using the hypermedia paradigm. We describe an extension of the Object‐Oriented Hypermedia Design Method (OOHDM) and present an improvement of the popular Model‐View‐Controller (MVC) metaphor to incorporate the concept of located object we illustrate the idea with a framework implementation using Jakarta Struts. We first review the state of the art of this kind of software systems, stressing the need of a systematic design and implementation approach we briefly present a light extension to the OOHDM design approach, incorporating physical objects and “walkable” links. We next present a Web application framework for deploying physical hypermedia software and show an example of use. We evaluate our approach and finally we discuss some further work we are pursuing.

Abstract

Purpose – We examine the meanings of objects that have indexical (or direct first-hand) connections to celebrities. In so doing, we distinguish between the meanings of proximal indexicality versus contagious indexicality. We reveal how these disparate meanings are linked to how consumers use a celebrity object, either by displaying the object or by using the object as the celebrity had originally used the object.

Methodology – Our informants were consumers participating in sales of celebrity-owned items. Data include videotaped depth interviews, photographs of auction participants and celebrity objects, field notes, and auction catalogue descriptions.

Findings – Some consumers were fans who desired to be close to the celebrity, while others participating in celebrity-object auctions desired to become a celebrity themselves. Those that desired to be close to the celebrity (fans) were attracted to the proximal indexical meaning of the object, in which an indexical link conveyed a perceived closeness between the perceiver and the signified (e.g., consumer and celebrity) through the indexically linked object. Those that desired to become a celebrity themselves were attracted to the contagious indexical meaning of the object which facilitates a perceived contamination of the perceiver (e.g., consumer) by the essence of the signified (e.g., celebrity) through the indexically linked object.

Contributions – We contribute to the Peircian semiotic framework as used in consumer research by differentiating between the meanings of proximal indexicality and contagious indexicality. We show these meanings are linked to consumers’ display use versus the original use of the celebrity-owned object.

Abstract

This paper presents a systematic XML Schema design approach which conceptually captures semantics of the problem domain at conceptual level and represents such semantics in XML Schema at schema level. At the conceptual level, objects, their inter‐relationships and constraints are semantically powered by object‐oriented models. At the schema level, these conceptual semantics are comprehensively represented in textbased representation of XML Schema using various schema components and design styles, each of which offers different quality characteristics. Two primary design styles in use are nesting and linking. The nesting design styles are developed based on the choice of schema components and their definition/declaration scopes (global vs. local), whereas the linking design styles use referencing facilities provided by XML Schema and other XML technologies such as XLink and XPointer. With an in‐depth analysis of outstanding problems of existing approaches, the proposed design approach is motivated to help improve the quality and robustness of the XML documents in large‐scale XML‐based applications.

Abstract

Purpose

Research in the area of technology‐enhanced learning (TEL) throughout the last decade has largely focused on sharing and reusing educational resources and data. This effort has led to a fragmented landscape of competing metadata schemas, or interface mechanisms. More recently, semantic technologies were taken into account to improve interoperability. The linked data approach has emerged as the de facto standard for sharing data on the web. To this end, it is obvious that the application of linked data principles offers a large potential to solve interoperability issues in the field of TEL. This paper aims to address this issue.

Design/methodology/approach

In this paper, approaches are surveyed that are aimed towards a vision of linked education, i.e. education which exploits educational web data. It particularly considers the exploitation of the wealth of already existing TEL data on the web by allowing its exposure as linked data and by taking into account automated enrichment and interlinking techniques to provide rich and well‐interlinked data for the educational domain.

Findings

So far web‐scale integration of educational resources is not facilitated, mainly due to the lack of take‐up of shared principles, datasets and schemas. However, linked data principles increasingly are recognized by the TEL community. The paper provides a structured assessment and classification of existing challenges and approaches, serving as potential guideline for researchers and practitioners in the field.

Originality/value

Being one of the first comprehensive surveys on the topic of linked data for education, the paper has the potential to become a widely recognized reference publication in the area.

Abstract

Providing enhanced access and added value to electronic documents (e‐documents) will require interfaces that effectively mediate between the information seeking needs of the users and the information that the e‐document has to offer. A proposed information environment (PIE) to support effective and creative use of e‐documents to fulfil users’ various information tasks and needs is presented. Providing a suite of novel features and interactive tools that can be flexibly combined, the PIE allows users to apply multiple novel ways to intuitively query and navigate information in an e‐document. The querying and browsing processes in the PIE are supported by various interactive and visualisation techniques. Users work within a visually sovereign, integrated environment for information gathering and organising, based on navigable, fractional information objects that are also affiliated with rich metadata and additional layers of value‐adding information. This paper describes the conceptual design of the PIE and uses a representative scenario to show how the PIE is likely to be used for interacting with electronic journals (e‐journals) and the ability of the proposed environment to provide enhanced user interaction and value‐adding.

Abstract

Purpose

Knowledge- and communication-intensive domains still long for a better support of creativity that considers legal requirements, compliance rules and administrative tasks as well, because current systems focus either on knowledge representation or business process management. The purpose of this paper is to discuss our model of integrated knowledge and business process representation and its presentation to users.

Design/methodology/approach

The authors follow a design science approach in the environment of patent prosecution, which is characterized by a highly standardized, legally prescribed process and individual knowledge study. Thus, the research is based on knowledge study, BPM, graph-based knowledge representation and user interface design. The authors iteratively designed and built a model and a prototype. To evaluate the approach, the authors used analytical proof of concept, real-world test scenarios and case studies in real-world settings, where the authors conducted observations and open interviews.

Findings

The authors designed a model and implemented a prototype for evolving and storing static and dynamic aspects of knowledge. The proposed solution leverages the flexibility of a graph-based model to enable open and not only continuously developing user-centered processes but also pre-defined ones. The authors further propose a user interface concept which supports users to benefit from the richness of the model but provides sufficient guidance.

Originality/value

The balanced integration of the data and task perspectives distinguishes the model significantly from other approaches such as BPM or knowledge graphs. The authors further provide a sophisticated user interface design, which allows the users to effectively and efficiently use the graph-based knowledge representation in their daily study.

Abstract

Purpose

The purpose of this article is to understand the meaning of museum objects from an information perspective. Links are made from Buckland's conceptual information framework as a semiotic to museum object as “document” and finally to user experience of these museum “documents”. The aim is to provide a new lens through which museum studies researchers can understand museum objects and for LIS researchers to accept museum objects as another form of document to be studied.

Design/methodology/approach

A conceptual and comparative analysis of Buckland's information typology as a semiotic. Outcome of analysis forms a model of understanding the museum object as a “document” that is accessed by users on a continuum of experience.

Findings

Michael Buckland's information typology is insightful and useful for a broad understanding of what all heritage institutions have in common: the physical object. Buckland helps us see the museum as an information system, the museum object as a document, and the multidimensional use of the concept information and its semiotic ramifications.

Originality/value

Buckland's typology is important to an understanding of the museum system and museum object in both LIS and museum studies. The concept of “document” opens up a broader perspective, which creates, rather than limits understandings of the human relationship with information. This expanded concept of “document” as sign/semiotic helps us understand user experience in ways not previously explored in the convergence of museums and information studies, from the practical to the theoretical. In this inclusive sense, Buckland's concept of document is a unifying theoretical concept for museums, libraries, and archives.
