OntoEng: A design method for ontology engineering in information systems

This paper addresses the design problem relating to ontology engineering in the discipline of information systems. Ontology engineering is a realm that covers issues related to ontology development and use throughout its life span. Nowadays, ontology as a new innovation promises to improve the design, semantic integration, and utilization of information systems. Ontologies are the backbone of knowledge-based systems. In addition, they establish sharable and reusable common understanding of specific domains amongst people, information systems, and software agents. Notwithstanding, the ontology engineering literature does not provide adequate guidance on how to build, evaluate, and maintain ontologies. On the basis of the gathered experience during the development of V4 Telecoms Business Model Ontology as well as the conducted integration of the related literature from the design science paradigm, this paper introduces OntoEng and its application as a novel systematic design method for ontology engineering

Strategic Human Capital Management: NRC Could Better Manage the Size and Composition of Its Workforce by Further Incorporating Leading Practices

[Excerpt] After the passage of the Energy Policy Act of 2005, which included tax incentives for nuclear energy, NRC significantly expanded its workforce to meet the demands of an anticipated increase in workload that ultimately did not occur. More recently, a forecast for reduced growth in the nuclear industry prompted NRC to develop plans for changing its structure and workforce to better respond to changes in the nuclear industry. Strategic human capital planning is one of several actions the agency is taking. The explanatory statement accompanying the Consolidated Appropriations Act for fiscal year 2016 included a provision for GAO to report on NRC’s workforce management. GAO examined NRC’s strategic human capital management efforts and the extent to which these efforts incorporate leading practices. GAO reviewed NRC’s strategic workforce plan and other related documents and interviewed knowledgeable NRC officials

An Agent-based approach to modelling integrated product teams undertaking a design activity.

The interactions between individual designers, within integrated product teams, and the nature of design tasks, all have a significant impact upon how well a design task can be performed, and hence the quality of the resultant product and the time in which it can be delivered. In this paper we describe an ongoing research project which aims to model integrated product teams through the use of multi-agent systems. We first describe the background and rationale for our work, and then present our initial computational model and results from the simulation of an integrated product team. The paper concludes with a discussion of how the model will evolve to improve the accuracy of the simulation

Conceptual modelling and the quality of ontologies: A comparison between object-role modelling and the object paradigm

Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard. The quality of an ontology is strongly based on the design method employed. This paper addresses the design problems related to the modelling of ontologies, with specific concentration on the issues related to the quality of the conceptualisations produced. The paper aims to demonstrate the impact of the modelling paradigm adopted on the quality of ontological models and, consequently, the potential impact that such a decision can have in relation to the development of software applications. To this aim, an ontology that is conceptualised based on the Object Role Modelling (ORM) approach is re-engineered into a one modelled on the basis of the Object Paradigm (OP). Next, the two ontologies are analytically compared using the specified criteria. The conducted comparison highlights that using the OP for ontology conceptualisation can provide more expressive, reusable, objective and temporal ontologies than those conceptualised on the basis of the ORM approach

An Analysis of Service Ontologies

Services are increasingly shaping the world’s economic activity. Service provision and consumption have been profiting from advances in ICT, but the decentralization and heterogeneity of the involved service entities still pose engineering challenges. One of these challenges is to achieve semantic interoperability among these autonomous entities. Semantic web technology aims at addressing this challenge on a large scale, and has matured over the last years. This is evident from the various efforts reported in the literature in which service knowledge is represented in terms of ontologies developed either in individual research projects or in standardization bodies. This paper aims at analyzing the most relevant service ontologies available today for their suitability to cope with the service semantic interoperability challenge. We take the vision of the Internet of Services (IoS) as our motivation to identify the requirements for service ontologies. We adopt a formal approach to ontology design and evaluation in our analysis. We start by defining informal competency questions derived from a motivating scenario, and we identify relevant concepts and properties in service ontologies that match the formal ontological representation of these questions. We analyze the service ontologies with our concepts and questions, so that each ontology is positioned and evaluated according to its utility. The gaps we identify as the result of our analysis provide an indication of open challenges and future work

Conceptual Modelling and The Quality of Ontologies: Endurantism Vs. Perdurantism

Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard. The quality of an ontology is strongly based on the design method employed. This paper addresses the design problems related to the modelling of ontologies, with specific concentration on the issues related to the quality of the conceptualisations produced. The paper aims to demonstrate the impact of the modelling paradigm adopted on the quality of ontological models and, consequently, the potential impact that such a decision can have in relation to the development of software applications. To this aim, an ontology that is conceptualised based on the Object-Role Modelling (ORM) approach (a representative of endurantism) is re-engineered into a one modelled on the basis of the Object Paradigm (OP) (a representative of perdurantism). Next, the two ontologies are analytically compared using the specified criteria. The conducted comparison highlights that using the OP for ontology conceptualisation can provide more expressive, reusable, objective and temporal ontologies than those conceptualised on the basis of the ORM approach

Cultural Diversity, Competencies and Behaviour: Workforce Adaptation of Minorities

The increasing mobility of people around the world has resulted in an increasingly culturally diverse workforce, particularly in Canada, where multiculturalism is embraced and government policies are enforced in order to ensure that the Canadian workforce is representative of its population in terms of race and ethnicity. However, there are still differences in employment conditions between minorities and non-minorities in Canada. Many organizations use competency modeling as a basis for employment decisions, particularly for managerial jobs, and some of the behaviours outlined in competency models can be linked to what has been identified as organizational citizenship behaviours (OCB). This use of competencies (and thus possibly OCBS) may be a contributor to the employment gap in Canada. Acculturation as a way to mitigate this gap is also discussed. More research in these areas needs to be done to bridge the gap between practice and theory.cultural diversity, acculturation, competency, OCB

Do Competency Frameworks Influence Business Performance? An Empirical Study of the Nigerian Banking Sector

The competency-based management system has grown to become one of the most influential HRM tools of the 21st century. However, there remains limited empirical data addressing the relationship between the adoption of a competency framework and organizational performance. The study reported upon in this paper is based within the Nigerian banking sector. A qualitative methodological approach was adopted, employing interviews with employees of the top ten high street banks in Nigeria. The result of the field data was subsequently analyzed using NVivo in order to achieve the aim of the research. The findings revealed that competency-based management frameworks are being used and that indeed they are a key management tool within the selected Nigerian banks. Importantly, the findings clearly suggest the adopted competency frameworks are having a positive impact on the banks’ performance
