A literature review on business process modelling: new frontiers of reusability

Business process modelling (BPM) has become fundamental for modern enterprises due to the increasing rate of organisational change. As a consequence, business processes need to be continuously (re-)designed as well as subsequently aligned with the corresponding enterprise information systems. One major problem associated with the design of business processes is reusability. Reuse of business process models has the potential of increasing the efficiency and effectiveness of BPM. This article critically surveys the existing literature on the problem of BPM reusability and more specifically on that State-of-the-Art research that can provide or suggest the ‘elements’ required for the development of a methodology aimed at discovering reusable conceptual artefacts in the form of patterns. The article initially clarifies the definitions of business process and business process model; then, it sets out to explore the previous research conducted in areas that have an impact on reusability in BPM. The article concludes by distilling directions for future research towards the development of apatterns-based approach to BPM; an approach that brings together the contributions made by the research community in the areas of process mining and discovery, declarative approaches and ontologies.

A framework for deriving semantic web services

Web service-based development represents an emerging approach for the development of distributed information systems. Web services have been mainly applied by software practitioners as a means to modularize system functionality that can be offered across a network (e.g., intranet and/or the Internet). Although web services have been predominantly developed as a technical solution for integrating software systems, there is a more business-oriented aspect that developers and enterprises need to deal with in order to benefit from the full potential of web services in an electronic market. This ‘ignored’ aspect is the representation of the semantics underlying the services themselves as well as the ‘things’ that the services manage. Currently languages like the Web Services Description Language (WSDL) provide the syntactic means to describe web services, but lack in providing a semantic underpinning. In order to harvest all the benefits of web services technology, a framework has been developed for deriving business semantics from syntactic descriptions of web services. The benefits of such a framework are two-fold. Firstly, the framework provides a way to gradually construct domain ontologies from previously defined technical services. Secondly, the framework enables the migration of syntactically defined web services toward semantic web services. The study follows a design research approach which (1) identifies the problem area and its relevance from an industrial case study and previous research, (2) develops the framework as a design artifact and (3) evaluates the application of the framework through a relevant scenario.

Ontology engineering for simulation component reuse

Commercial-off-the-shelf (COTS) Simulation Packages (CSP) are widely used in industry primarily due to economic factors associated with developing proprietary software platforms. Regardless of their widespread use, CSPs have yet to operate across organizational boundaries. The limited reuse of CSPs is affected by the same semantic issues that restrict the inter-organizational use of software components and Web services. The current representations of Web components are predominantly syntactic in nature lacking the fundamental semantic underpinning required to support discovery on the emerging Semantic Web. We present new research that partially alleviates the problem of limited semantic interoperability and reuse of simulation components in CSPs. Semantic models, in the form of ontologies, utilized by Web service discovery and deployment architecture provide one approach to support simulation model reuse. Although specific to CSPs this work has wider implications for the simulation community.

Semantic transformation of web services

Web services have become the predominant paradigm for the development of distributed software systems. Web services provide the means to modularize software in a way that functionality can be described, discovered and deployed in a platform independent manner over a network (e.g., intranets, extranets and the Internet). The representation of web services by current industrial practice is predominantly syntactic in nature lacking the fundamental semantic underpinnings required to fulfill the goals of the emerging Semantic Web. This paper proposes a framework aimed at (1) modeling the semantics of syntactically defined web services through a process of interpretation, (2) scoping the derived concepts within domain ontologies, and (3) harmonizing the semantic web services with the domain ontologies. The framework was validated through its application to web services developed for a large financial system. The worked example presented in this paper is extracted from the semantic modeling of these financial web services.

Information sharing through inter‐organisational systems in local government

Purpose – The dilemma of implementing and adopting inter‐organisational systems (IOS) that enable information sharing in an electronic fashion has been regarded as an inevitable issue for the public sector. The majority of previous studies have mainly focused on Central or Federal level organisations, and more importantly applied so‐called old fashion theoretical lenses, hence failed to capture the extensive picture of information sharing in an inter‐organisational and inter‐departmental settings. Therefore, the purpose of this paper is to investigate the barriers and enablers of information sharing in local level in order to clarify why sharing information in local level differs from the central/federal level, and why innovation adoption theories are not sufficient enough to explore an inter‐organisational phenomenon.Design/methodology/approach – A systematic literature review on technology adoption in public sector is carried out in order to select a suitable theoretical lens. Hence, based on previous r...

Electronic information sharing in local government authorities: Factors influencing the decision-making process

Local Government Authorities (LGAs) are mainly characterised as information-intensive organisations. To satisfy their information requirements, effective information sharing within and among LGAs is necessary. Nevertheless, the dilemma of Inter-Organisational Information Sharing (IOIS) has been regarded as an inevitable issue for the public sector. Despite a decade of active research and practice, the field lacks a comprehensive framework to examine the factors influencing Electronic Information Sharing (EIS) among LGAs. The research presented in this paper contributes towards resolving this problem by developing a conceptual framework of factors influencing EIS in Government-to-Government (G2G) collaboration. By presenting this model, we attempt to clarify that EIS in LGAs is affected by a combination of environmental, organisational, business process, and technological factors and that it should not be scrutinised merely from a technical perspective. To validate the conceptual rationale, multiple case study based research strategy was selected. From an analysis of the empirical data from two case organisations, this paper exemplifies the importance (i.e. prioritisation) of these factors in influencing EIS by utilising the Analytical Hierarchy Process (AHP) technique. The intent herein is to offer LGA decision-makers with a systematic decision-making process in realising the importance (i.e. from most important to least important) of EIS influential factors. This systematic process will also assist LGA decision-makers in better interpreting EIS and its underlying problems. The research reported herein should be of interest to both academics and practitioners who are involved in IOIS, in general, and collaborative e-Government, in particular.

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.

Hidden assumptions and their influence on clinicians' acceptance of new IT systems in the NHS

The UK National Health Service (NHS) is embarking on the largest investment programme in Information Technology (IT). The National Programme for IT (NPfIT) in the NHS is the biggest civil IT project in the world and seeks to revolutionise the way care is delivered, drive up quality and make more effective use of resources of the NHS. Despite these high expectations, the NHS has historically experienced some high profile IT failures and the sponsors of the programme admitted that there remain a number of critical barriers to the implementation of the programme. Clinicians’ reluctance to accept new IT systems at a local level is seen to be a major factor in this respect. Focusing on such barriers, this paper reports research that explored and explained why such reluctance occurs in the NHS. The main contribution of this research derives from the distinctive approach based on Kelly’s Personal Construct Theory (PCT) to understand the ‘reluctance’. The argument presented in the paper indicates that such reluctance should be viewed not as deliberate resistance imposed by clinicians, but as their inability of changing their established group personal constructs related to ISDD activities. Therefore, this paper argues that the means that could occur to reduce the ‘reluctance’ are creative rather than corrective or normative. The research took place in a NHS Trust and the paper pays considerable attention to technological, behavioural and clinical perspectives that emerged from the study. The research was conducted as a case study in a NHS trust and data was collected from two local NHS IT project. The main research participants in this study were: (a) IT professionals including IT project managers and senior IT managers; and (b) senior clinicians.

Guidelines for Developing Ontological Architectures in Modelling and Simulation

This book is motivated by the belief that “a better understanding of ontology, epistemology, and teleology” is essential for enabling Modelling and Simulation (MS ones where building an ontology – and, we shall suggest, an epistemology – as an integrated part of their design will enable them to reach the next level of ‘intelligence’.

Toward the Automation of Business Process Ontology Generation

Semantic Business Process Management (SBPM) utilises semantic technologies (e.g., ontology) to model and query process representations. There are times in which such models must be reconstructed from existing textual documentation. In this scenario the automated generation of ontological models would be preferable, however current methods and technology are still not capable of automatically generating accurate semantic process models from textual descriptions. This research attempts to automate the process as much as possible by proposing a method that drives the transformation through the joint use of a foundational ontology and lexico-semantic analysis. The method is presented, demonstrated and evaluated. The original dataset represents 150 business activities related to the procurement processes of a case study company. As the evaluation shows, the proposed method can accurately map the linguistic patterns of the process descriptions to semantic patterns of the foundational ontology to a high level of accuracy, however further research is required in order to reduce the level of human intervention, expand the method so as to recognise further patterns of the foundational ontology and develop a tool to assist the business process modeller in the semi-automated generation of process models.
