Abstract

Purpose

Ontology of a domain mainly consists of a set of concepts and their semantic relations. It is typically constructed and maintained by using ontology editors with substantial human intervention. It is desirable to perform the task automatically, which has led to the development of ontology learning techniques. One of the main challenges of ontology learning from the text is to identify key concepts from the documents. A wide range of techniques for key concept extraction have been proposed but are having the limitations of low accuracy, poor performance, not so flexible and applicability to a specific domain. The propose of this study is to explore a new method to extract key concepts and to apply them to literature in the nuclear domain.

Design/methodology/approach

In this article, a novel method for key concept extraction is proposed and applied to the documents from the nuclear domain. A hybrid approach was used, which includes a combination of domain, syntactic name entity knowledge and statistical based methods. The performance of the developed method has been evaluated from the data obtained using two out of three voting logic from three domain experts by using 120 documents retrieved from SCOPUS database.

Findings

The work reported pertains to extracting concepts from the set of selected documents and aids the search for documents relating to given concepts. The results of a case study indicated that the method developed has demonstrated better metrics than Text2Onto and CFinder. The method described has the capability of extracting valid key concepts from a set of candidates with long phrases.

Research limitations/implications

The present study is restricted to literature coming out in the English language and applied to the documents from nuclear domain. It has the potential to extend to other domains also.

Practical implications

The work carried out in the current study has the potential of leading to updating International Nuclear Information System thesaurus for ontology in the nuclear domain. This can lead to efficient search methods.

Originality/value

This work is the first attempt to automatically extract key concepts from the nuclear documents. The proposed approach will address and fix the most of the problems that are existed in the current methods and thereby increase the performance.

Abstract

Purpose

Ontologies are used to formally describe the concepts within a domain in a machine-understandable way. Matching of heterogeneous ontologies is often essential for many applications like semantic annotation, query answering or ontology integration. Some ontologies may include a large number of entities which make the ontology matching process very complex in terms of the search space and execution time requirements. The purpose of this paper is to present a technique for finding degree of similarity between ontologies that trims down the search space by eliminating the ontology concepts that have less likelihood of being matched.

Design/methodology/approach

Algorithms are written for finding key concepts, concept matching and relationship matching. WordNet is used for solving synonym problems during the matching process. The technique is evaluated using the reference alignments between ontologies from ontology alignment evaluation initiative benchmark in terms of degree of similarity, Pearson’s correlation coefficient and IR measures precision, recall and F-measure.

Findings

Positive correlation between the degree of similarity and degree of similarity (reference alignment) and computed values of precision, recall and F-measure showed that if only key concepts of ontologies are compared, a time and search space efficient ontology matching system can be developed.

Originality/value

On the basis of the present novel approach for ontology matching, it is concluded that using key concepts for ontology matching gives comparable results in reduced time and space.

Abstract

Purpose

This paper aims to report on the design and development of a new approach for automatic classification and subject indexing of research documents in scientific digital libraries and repositories (DLR) according to library controlled vocabularies such as DDC and FAST.

Design/methodology/approach

The proposed concept matching-based approach (CMA) detects key Wikipedia concepts occurring in a document and searches the OPACs of conventional libraries via querying the WorldCat database to retrieve a set of MARC records which share one or more of the detected key concepts. Then the semantic similarity of each retrieved MARC record to the document is measured and, using an inference algorithm, the DDC classes and FAST subjects of those MARC records which have the highest similarity to the document are assigned to it.

Findings

The performance of the proposed method in terms of the accuracy of the DDC classes and FAST subjects automatically assigned to a set of research documents is evaluated using standard information retrieval measures of precision, recall, and F1. The authors demonstrate the superiority of the proposed approach in terms of accuracy performance in comparison to a similar system currently deployed in a large scale scientific search engine.

Originality/value

The proposed approach enables the development of a new type of subject classification system for DLR, and addresses some of the problems similar systems suffer from, such as the problem of imbalanced training data encountered by machine learning-based systems, and the problem of word-sense ambiguity encountered by string matching-based systems.

Abstract

Purpose

The paper aims to produce new key terminologies for the microfoundations of Islamic economics. The paper attempts to investigate the microfoundations of Islamic economics by exploring new perspective in the key concepts and key terminologies that would explain the behavior of individual and society in an Islamic ethical framework.

Design/methodology/approach

The paper is a conceptual paper that attempts to explore the microfoundations of Islamic economics from the primary sources of Qur’anic texts. Literature on the topics, from an Islamic and mainstream economics perspective, are reviewed critically in a comparative perspective.

Findings

The key concepts of self-interest, utility maximization and rationality are critically evaluated in an Islamic perspective and new key concepts of huquq, maslahah maximization and taqwa are proposed as alternatives. Those new key terminologies will broaden the horizon in understanding of economic realities of man and society and their relationship and well-being.

Research limitations/implications

The paper is based on conceptual explorations of literature in the microfoundations of economics in the mainstream economics and Islamic economics. This is a conceptual paper, so it did not use any empirical analysis.

Practical implications

The findings of this paper will give insights of the microfoundations of Islamic economics as a discipline. Those unique key terminologies derived from the textual source of Islam (nusus) and intellectual tradition (turath) are important in the attempt to develop a solid body of knowledge.

Originality/value

The paper proposes new key concepts and terminologies to be the microfoundations of Islamic economics as a discipline. It is a new approach in understanding behavior of individual and society in Islamic perspective which are different from the other approach, which modifies the conventional terminologies by adding “Islamic” prefix, such as “Islamic” utility or “Islamic” rationality.

Abstract

A characteristic of agile organizations is the development of innovative products and processes. It has been shown that a key factor of success in managing innovative projects is the existence of key persons. Empirical studies on innovation management show that key persons who are able to overcome existing innovation barriers play a decisive role for innovation success. The basic theoretical concepts behind these findings are the “gatekeeper concept” and the “promotor model”. The two concepts are compared under a static and a dynamic perspective. It will be shown that under a dynamic view, one can combine the gatekeeper concept and the promotor model to a powerful management concept for supporting agility in organizations.

Abstract

Purpose

Although the literature is clear on what comprises effective project stakeholder management, communication between key stakeholders and project managers is often ineffective. Research is silent on stakeholders' insufficient knowledge of project management terminology, which is a barrier for such effective communication. This paper aims to identify the project management concepts that key stakeholders should understand to improve effective communication.

Design/methodology/approach

This paper employs a three-step research design. In the first step, based on threshold concept theory, the authors identify the key project management concepts through interviews with 20 project management practitioners, trainers and trainees. In the second step, the authors confirm the findings from the first step and identify effective approaches to enhance project stakeholders' communication through seven additional interviews with project stakeholders. In the third step, the authors construct a functional model of the research findings by employing a system-level modeling tool.

Findings

This research identifies five project management threshold concepts (TC) that are challenging for project stakeholders to understand (1) project benefits, (2) the iron triangle, (3) the critical path, (4) uncertainty and (5) project leadership. Following these knowledge barriers, the paper proposes unique approaches to develop effective project stakeholder communication.

Originality/value

This paper advances project stakeholder management research by identifying knowledge barriers and providing project managers with more effective approaches to better engage with their stakeholders.

Abstract

Purpose

The aim of this paper is to explore and better understand e-relationship marketing and to identify elements (key concepts) that are predominant to ensure success via the internet.

Design/methodology/approach

The exploratory cognitive mapping technique (Cossette, 2004) employs three types of respondents, namely a banking expert, online banking customer and academic expert.

Findings

The study points up similarities with traditional relationship marketing (e.g. satisfaction, commitment by bank) and identifies several new concepts spawned by the web-based environment. More precisely, the study highlights the importance of the simplicity and ease of the customer's web experience.

Research limitations/implications

The exploratory and qualitative nature of this study opens the door to validation with a broader sample using a self-administered questionnaire developed based on the cognitive mapping technique.

Practical implications

In addition to guaranteeing customer satisfaction, it is important: that customers perceive the bank's investment in and commitment to the e-relationship strategy; and, that customers enjoy a highly positive web experience (e.g. perceived quality of site and ease-of-use).

Originality/value

Research findings result in an enhanced understanding of e-relationship marketing. Also, given the combination of sparse use of cognitive mapping in marketing and investigation of three different types of subjects (banking expert, online banking customer and academic expert), the findings lend originality while making a substantive theoretical contribution to topical literature.

Abstract

Purpose

The purpose of this paper is to explore whether and how the intellectual capital (IC) approach and concepts could be fruitfully adapted to study the smart city phenomenon from a managerial point of view.

Design/methodology/approach

This study is based on a long-term, in-depth ethnographic exploration of the vast global community, which is created around the smart city movement.

Findings

The analysis suggests that, in order to effectively analyse a smart city context through the IC lens, the traditional IC framework needs to be extended for: expected outcomes, which should also include sustainability, resilience and quality of life; categories of key resources, which should also include institutional capital and environmental capital; units of analysis, which should also include territorial systems, such as transportation or waste; and key managerial challenges implied. As a final result, a smart city intellectual capital (SC-IC) framework is proposed.

Research limitations/implications

Most of the cases analysed in this study are European; further studies are advisable to better investigate non-European smart city contexts.

Practical implications

The paper suggests that the knowledge management, project portfolio management and network management approaches are crucial to better support managerial practices in smart city organizations.

Originality/value

The SC-IC framework allows for a clear definition of the smart city organization, as a new knowledge-based, project-oriented, network-shaped type of organization. Therefore, the SC-IC framework provides smart city research with a consistent rooting in management studies. Further, this paper contributes to the fourth stage of IC research.

Abstract

Purpose

The Iron Triangle, also called the Triple Constraint, is a central concept to project management research and practice, representing the relationship between key performance criteria. However, there is disagreement about which criteria should be represented on the vertices of this triangle. The purpose of this paper is to explore which concepts are part of the Iron Triangle, and how these concepts have changed over time.

Design/methodology/approach

This paper explores 45 years of project management research, drawing on a database of 109,804 records from 1970 to 2015. Three corpora were constructed, representing the project management and Time, Cost, and Quality Management literature. Time and Cost are consistently identified as part of the Iron Triangle. However, the status of quality is contested. Key concepts in the project management literature were explored using scientometric research techniques, to understand the relationship between these concepts.

Findings

Significant links were found between Time, Cost, and Quality, verifying these concepts as the vertices on the Iron Triangle. These links were significantly stronger than links to alternatives, such as Scope, Performance, or Requirements. Other concepts that are core to the Iron Triangle were also identified, and how these have changed over time.

Originality/value

This research develops the understanding of a key project management concept by clarifying which concepts are part of the Iron Triangle, based on evidence of how the concept is used in research. This paper also reveals the context in which this concept is used, and how this has changed over the last 45 years.
