Abstract

Examines the relationship between systems and their users from the knowledge discovery perspective. Recently knowledge discovery in databases has made important progress, but it may also bring some potential problems to database design, such as issues related to database security, as an unauthorized user may derive highly sensitive knowledge from unclassified data. There is a need for a comprehensive study on knowledge discovery in human‐computer symbiosis. Borrowing terms from algorithm design and artificial intelligence literature, proposes a notion called database‐user adversarial partnership. This notion is general enough to cover various knowledge discovery and security issues related to databases and their users. Furthermore, the notion of database‐user adversarial partnership can be further generalized into system‐user adversarial partnership. Opportunities provided by knowledge discovery techniques and potential social implications are discussed and illustrated by examples.

Abstract

Purpose

The purpose of this paper is to describe how discovery and creation opportunities transition from one to the other and thereby clarify the relationship between opportunity types. This theoretical work will offer insight for studying opportunities and clarify the different practical implications of different opportunity types.

Design/methodology/approach

To further the understanding of opportunity types, the paper employs Dubin’s (1978) theory building methodology focussing specifically on the concepts of system states. Approaching opportunity types as system states clarifies the relationship between discovery and creation opportunities.

Findings

This research argues that opportunities transition from creation opportunities to discovery opportunities. Furthermore, understanding the opportunity state can clarify the practical implications for entrepreneurs. In particular, entrepreneurs in discovery states employ different processes regarding human resources, strategy, financing, planning, leadership, and potential competitive advantage than entrepreneurs pursuing creation states.

Originality/value

This paper offers value to researchers by clarifying the differences between opportunity types. To date, there has been little to no investigation into how opportunity types change from one type to another. This research offers to clarify the debate about the existence of different opportunity types and move the discussion forward theoretically. Additionally, this manuscript offers practical insights for entrepreneurs pursuing different types of opportunities.

Abstract

Purpose

This paper aims to provide an overview of the emergence of resource discovery systems and services along with their advantages and best practices including current landscapes. It reports the development of a resource discovery system by using the “VuFind” software and describes other technological tools, software, standards and protocols required for the development of the prototype.

Design/methodology/approach

This paper describes the process of integrating VuFind (resource discovery tool) with Koha (integrated library system), DSpace (repository software) and Apache Tika (as full-text extractor for full-text searching), etc.

Findings

The proposed model performs like other existing commercial and open source Web-scale resource discovery systems and is capable of harvesting resources from different subscribed or external sources replacing a library’s OPAC.

Originality/value

This discovery system is an important add-on to designing a one-stop access in place of the existing retrieval silos in libraries. This system is capable of indexing a variety of content within and beyond library collections. This work may help library professionals and administrators in designing their discovery system, as well as vendors to improve their products, to provide different library-friendly services.

Abstract

Purpose

The purpose of this paper is to analyse the paradigm shift of library automation to resource discovery by exploring the applications of resource discovery. The present status of India on adapting resource discovery applications is discussed.

Design/methodology/approach

An evaluative method to examine the status quo of India automation and resource discovery scenario is drawn with a related literature review. Moreover, various pertinent global challenges of embracing discovery tools in the digital environment are highlighted.

Findings

The growth of the Indian library automation industry is booming. However, library software adaptation, next‐generation catalogue enhancements and community development avenues are dearth, seemingly remote and far from satisfactory.

Originality/value

The paper focuses on the emerging scenario of resource discovery applications with an overview of global challenges.

Abstract

Purpose

The purposes of this paper are to understand the user information seeking (IS) process under a new service system, to explore how users construct strategies and to identify the influences of the new service system on the IS process and behaviour.

Design/methodology/approach

A quality research study design that included questionnaires survey, observation, thinking-aloud and interviews was employed. In all, 20 participants from 12 social science disciplines at Sichuan University, Chengdu, China were observed using the proposed Discovery Service system. The user IS process characteristics and taxonomy were analysed, and the stages matrix of IS under new system was built.

Findings

Users’ IS processes under the new system proved to be very complex. The features of three process stages, i.e. searching, scanning and verifying stages, and four different behaviour patterns were identified. Moreover, characteristics of IS behaviour under the new service system were described.

Originality/value

User IS behaviour was addressed in a new service system context in this study, as has seldom been done in previous IS research. A comprehensive and user-centred understanding of users’ exploratory practices in a new service system context was obtained, which will inform the development of information services for digital libraries. In addition, it indicated that the uncertainty of the IS process should be addressed by considering the relationships among IS, information retrieval and user-computer interaction.

Abstract

Purpose

As discovery systems take the library world by storm, there is a new opportunity for user‐centred information literacy programs to emerge. This paper aims to explore the impact that new web‐scale discovery systems might have on information literacy programs and pedagogical approaches to library instruction.

Design/methodology/approach

Utilizing both a conceptual approach and a case study of one particular library, various questions and possible answers are discussed with the goal of opening new avenues for information literacy instruction.

Findings

Discovery systems offer new possibilities to shift instruction programs away from their historical focus on explanatory searching and citing, towards exploratory higher level thinking in relation to evaluating and using information itself. As library search gets easier and varied platforms become unified, the focus of information literacy on search rules and platform choice and navigation is (finally) able to truly give way to critical thinking and imaginative exploration.

Originality/value

Many libraries have recently or are currently adopting discovery systems, but few have begun to explore and recognize the potential for a new era of instructional possibilities. This paper acts as a base for continuing exploration and discussion in this area.

Abstract

The paper aims to provide a non‐technical introduction to the new procedures being used to extract knowledge from databases. The reasons for developing knowledge discovery methods are discussed ± primarily, the current production of very large databases that may include many data relations not explicit in the database structure. The background in machine learning is indicated. The methods used are described for such techniques as classification (sorting data into predefined classes), clustering (developing ab initio a data classification) and the detection of deviations from pre‐established norms. Examples of the applications of these methods are given. The paper concludes with some brief thoughts about the potential use of knowledge discovery in the information field.

Abstract

The management of autonomous, heterogeneous network resources and services provides new challenges which libraries are now addressing. This paper outlines an approach based on the construction of broker services which mediate access to resources. It outlines a framework – the MODELS Information Architecture – for thinking about the components of broker services and their logical arrangement. It describes several development projects and services which show how brokers are developing. It uses examples drawn from the serials environment to describe some of the issues. Technologists understand that they must build more stable and unobtrusive media. They must establish more coherent contexts into which the technology may disappear.

Abstract

Purpose

This paper aims to examine integrated library systems (ILS) and web-scale discovery services (WSDS) of the National Institute of Ranking Framework’s (NIRF) top-ranked universities for the “Overall” category in the 2020 rankings. Further, the authors analyse how the ILS-WSDS transitions work in the academic libraries of higher educational institutions (HEIs) in India.

Design/methodology/approach

The 200 top-ranked institutions in the NIRF rankings 2020 were chosen to evaluate their ILS-WSDS systems available through their library websites. Out of ten categories of NIRF rankings, the “Overall” category was selected as the institutions ranked under this category are discipline-independent and have a minimum of 1,000 full-time students in their undergraduate and graduate programmes.

Findings

The authors found that Koha is a leading ILS with 52 libraries (26%), followed by LibSys with 18 institutions (9%), SOUL with ten institutions (5%), AutoLib with eight institutions (4%), VTLS and NewGenLib with four institutions each (2%) and SLIM with three institutions (1.5%). In regards to WSDS, 73 institutions use Knimbus (36.5%), followed by 12 institutions using EBSCO Discovery Services (6%), two institutions using Ex Libris Summon and others include LS Discovery, VuFind and independent platform each at 0.5%. At the core of technology adoption, for the ILS to WSDS transitions, the uptake is found to be rather slow.

Originality/value

Many studies have explored ILS and WSDS India. However, this study attempts to assess the ILS in comparison with discovery services at academic libraries in the top ranking HEIs in India.

Abstract

Purpose

The purpose of this paper is to provide a critical analysis from an ethical perspective of how the concept of indigenous wayfinding and voyaging is mapped in knowledge representation, organization and discovery systems.

Design/methodology/approach

In this study, the Dewey Decimal Classification, the Library of Congress Subject Headings, the Library of Congress Classifications systems and the Web of Science citation database were methodically examined to determine how these systems represent and facilitate the discovery of indigenous knowledge of wayfinding and voyaging.

Findings

The analysis revealed that there was no dedicated representation of the indigenous practices of wayfinding and voyaging in the major knowledge representation, organization and discovery systems. By scattering indigenous practice across various, often very broad and unrelated classes, coherence in the record is disrupted, resulting in misrepresentation of these indigenous concepts.

Originality/value

This study contributes to a relatively limited research literature on representation and organization of indigenous knowledge of wayfinding and voyaging. This study calls to foster a better understanding and appreciation for the rich knowledge that indigenous cultures provide for an enlightened society.
