Towards a new approach for enterprise integration : the semantic modeling approach

Manufacturing today has become a matter of the effective and efficient application of information technology and knowledge engineering. Manufacturing firms’ success depends to a great extent on information technology, which emphasizes the integration of the information systems used by a manufacturing enterprise. This integration is also called enterprise application integration (here the term application means information systems or software systems). The methodology for enterprise application integration, in particular enterprise application integration automation, has been studied for at least a decade; however, no satisfactory solution has been found. Enterprise application integration is becoming even more difficult due to the explosive growth of various information systems as a result of ever increasing competition in the software market. This thesis aims to provide a novel solution to enterprise application integration. The semantic data model concept that evolved in database technology is revisited and applied to enterprise application integration. This has led to two novel ideas developed in this thesis. First, an ontology of an enterprise with five levels (following the data abstraction: generalization/specialization) is proposed and represented using unified modeling language. Second, both the ontology for the enterprise functions and the ontology for the enterprise applications are modeled to allow automatic processing of information back and forth between these two domains. The approach with these novel ideas is called the enterprise semantic model approach. The thesis presents a detailed description of the enterprise semantic model approach, including the fundamental rationale behind the enterprise semantic model, the ontology of enterprises with levels, and a systematic way towards the construction of a particular enterprise semantic model for a company. A case study is provided to illustrate how the approach works and to show the high potential of solving the existing problems within enterprise application integration

Implicit Measures of Lostness and Success in Web Navigation

In two studies, we investigated the ability of a variety of structural and temporal measures computed from a web navigation path to predict lostness and task success. The user’s task was to find requested target information on specified websites. The web navigation measures were based on counts of visits to web pages and other statistical properties of the web usage graph (such as compactness, stratum, and similarity to the optimal path). Subjective lostness was best predicted by similarity to the optimal path and time on task. The best overall predictor of success on individual tasks was similarity to the optimal path, but other predictors were sometimes superior depending on the particular web navigation task. These measures can be used to diagnose user navigational problems and to help identify problems in website design

Knowledge society arguments revisited in the semantic technologies era

In the light of high profile governmental and international efforts to realise the knowledge society, I review the arguments made for and against it from a technology standpoint. I focus on advanced knowledge technologies with applications on a large scale and in open- ended environments like the World Wide Web and its ambitious extension, the Semantic Web. I argue for a greater role of social networks in a knowledge society and I explore the recent developments in mechanised trust, knowledge certification, and speculate on their blending with traditional societal institutions. These form the basis of a sketched roadmap for enabling technologies for a knowledge society

“One Size Can Fit All” – On the Mass Production of Legal Transplants

Law reformers like the World Bank sometimes suggest that optimal legal rules and institutions can be recognized and then be recommended for law reform in every country in the world. Comparative lawyers have long been skeptical of such views. They point out that both laws and social problems are context-specific. What works in one context may fail in another. Instead of “one size fits all,” they suggest tailormade solutions. I challenge this view. Drawing on a comparison with IKEA’s global marketing strategy, I suggest that “one size fits all” can sometimes be not only a successful law reform strategy, but also not as objectionable as critics make it to be. First, whereas, “one size fits all” is deficient a functionalist position, it proves to be surprisingly successful as a formalist conception. Second, critics of legal transplants often insists on what can be called “best law” approach, whereas in law reform, what we sometimes need is law that is just” good enough” law. “Third, legal transplants no longer happen in isolation but rather on a global scale, so that context-specific rules are no longer necessarily local. This is not a plea for formal law, for commodification of laws, and for “one size fits all”. But it is a plea to overcome the romanticism and elitism that may lurk behind the seemingly benign suggestion that law reform must always be tailored to the specific societal context

The Return of the Poor Man: Jude the Obscure and Late Victorian Socialism

This essay examines Hardy\u27s decision at the end of his career as a novelist to return to the striking socialistic themes which had defined his first (unpublished) novel. Jude the Obscure is Hardy\u27s exploration of the spiritual and intellectual deprivation that attends the condition of the working-class poor. While the novel was reviled at the time as blatantly anti-marriage, its fiercest polemic is reserved for the soul-destroying economic and social systems which continued to keep the class structure rigidly intact. While Hardy was never a socialist himself, his final novel has much in common with the numerous socialist and radical movements that were emerging, merging, and dissolving during the final decades of Victoria\u27s reign

An exploration of knowledge and understanding – the eighth flow

The argument for understanding Lean construction as a socio-technical field is growing and the need to better consider the role of human beings within construction systems is becoming the dominant factor in project success. Many current attributes of lean already focus on people and on human engagement approaches but the field of lean construction addresses project environments that are often complex and highly variable. The authors argue that the successful delivery of these projects relies on the creation of a common understanding of the project objectives within the diverse value systems of project participants and wider society. Additionally, many of the new ways of working that lean thinking brings already support the creation of a common understanding and could be harnessed to better effect. Based on a literature review and supported by case study examples the authors explore the nature of knowledge and understanding and position them within an eight flow model for construction production. The findings indicate a need to reconsider the development of a common understand for each project due to the tacit nature of experiential knowledge held within the project team and the specificity and complexity of the project environment. As a result effort is required to generate and maintain a common understanding throughout the project duration. The continued attention and action required to maintain this common understanding elevates it to a flow of equal status to those identified in Koskela’s flow production model thus increasing the number of flows to eight. A significant lean construction case study is revisited and examined to identify interventions undertaken to achieve this generation and management of common understanding thus demonstrating that this development already exists, albeit intuitively, as an element of “lean thinking”

The wicked and complex in education: developing a transdisciplinary perspective for policy formulation, implementation and professional practice

The concept of 'wicked issues', originally developed in the field of urban planning, has been taken up by design educators, architects and public health academics where the means for handling 'wicked issues' has been developed through 'reflective practice'. In the education of teachers, whilst reflective practice has been a significant feature of professional education, the problems to which this has been applied are principally 'tame' ones. In this paper, the authors argue that there has been a lack of crossover between two parallel literatures. The literature on 'wicked issues' does not fully recognise the difficulties with reflective practice and that in education which extols reflective practice, is not aware of the 'wicked' nature of the problems which confront teachers and schools. The paper argues for a fresh understanding of the underlying nature of problems in education so that more appropriate approaches can be devised for their resolution. This is particularly important at a time when the government in England is planning to make teaching a masters level profession, briefly defined by the Quality Assurance Agency for Higher Education (QAA) benchmark statement as 'Decision-making in complex and unpredictable situations'. The paper begins by locating the argument and analysis of 'wicked problems' within the nature of social complexity and chaos. The second part of the paper explores implications for those involved in policy formation, implementation and service provision. Given the range of stakeholders in education, the paper argues for a trans-disciplinary approach recognising the multiple perspectives and methodologies leading to the acquisition of reticulist skills and knowledge necessary to boundary cross. © 2009 Taylor & Francis
