Abstract

Data warehousing has captured the attention of practitioners and researchers alike. But the design and optimization of data warehouses remains as an art rather than a science. This book presents the first comparative review of the state of the art and best current practice in data warehousing. It covers source and data integration, multidimensional aggregation, query optimization, update propagation, metadata management, quality assessment, and design optimization. Also, based on results of the European DWQ project, it offers a conceptual framework by which the architecture and quality of datawarehousing efforts can be assessed and improved using enriched metadata management combined with advanced techniques from databases, business modeling, and artificial intelligence

Abstract

Knowledge-containing documents and data about knowledge have been handled in stable environments by bureaucratic systems using very stable knowledge ontologies. These systems, though not always very effective in such environments, will become highly ineffective in environments where knowledge has to be updated and replaced frequently. Moreover, organizations in such dynamic environments also use knowledge from extemal resources extensively. This makes the development of a stable ontology for knowledge storage and retrieval particularly complicated. This paper describes eight context classes of knowledge ontology development and explores elements of a method for ontology development. These classes are based an the differences in contexts defined along three dimensions: knowledge dynamics, complexity and social dispersion. Ontology development matches these contexts and ontology needs defined by (logical and social) structure and ontology maturity. The classification framework and methodology are applied to two cases. The first case illustrates a descriptive use of our framework to characterize ontology development in an academic environment. The second case illustrates a normative use of our framework. The method proposed seemed to be empirically valid and rich and be useful for detecting options for ontology improvement.

Abstract

In contemporary practice it is widely asserted, that smart management of knowledge (KM) could be a new panacea for the ever-increasing market and environmental demands put an companies in order to become more flexible, leaming and innovative at the same time. Effective KM is becoming a strategic issue in innovative organizations. Traditionally, managers view knowledge as intangible: Being spread all over the company, it is predominantly hidden in all sorts of databases and in the tacit customs of their employees, and often of course it is securely and unattainable locked in their heads. Often managers have asked themselves difficult questions like: "How to manage something you can't see?" and "How do I know whether it is worth the effort?". Although KM as an issue can hardly be evaded nowadays, design-oriented research an how to come to grips with managing the company's intellectual capacities is still very limited. Action research, showing how KM is dealt with in actual practice, is lacking. Our contribution to the conference is straightforward. We wart to discuss the preliminary results of an action-research project that is currently carried out in a large Dutch bank. Our paper supports the ISMICK conference theme an the organization dimension of KM. Based an the literature an innovation, organizational learning and socio-technical systems design, a number of in-depth interviews were held to determine the possible contribution of KM to increase the controllability and flexibility of the automation department. A qualitative analysis of the data Show that over half of the problems (i.e. poor knowledge about the distinctive systems in the organization, insufficient skills levels, unproductive redundancy of activities, 'islands' of knowledge, and recurring mistakes) could be attributed to the company's inability to successfully manage its intellectual capital. Further analysis of the data showed, that the organizational structure and the maturity of the organization - in terms of Bolwijn & Kumpe (1991) - proved to be the dominant factor in determining the KM approach that would fit the organization. In order to lift the rigidities that resulted from the stock of systems to be maintained and from its bureaucratic structure, several suggestions were made in an attempt to solve the problems mentioned. Those suggestions have been discussed with stakeholders in the organization to increase their fitness for implementation. To improve KM in this organization asks for a multifocus renewal effort. Several approaches are distinguished (i.e. competence centers; dedicated career paths; cluster organization; knowledge infrastructure), each focused an a particular knowledge management problem. These proposals form a design oriented research agenda for the study at hand, while at the same time take the explicit aim to foster implementation in close collaboration with the main stakeholders.

Abstract

Purpose - Potential and benefits of classification schemes and thesauri in building organizational taxonomies cannot be fully utilized by organizations. Empirical data of building an organizational taxonomy by the top-down approach of using classification schemes and thesauri appear to be lacking. The paper seeks to make a contribution in this regard. Design/methodology/approach - A case study of building an organizational taxonomy was conducted in the information studies domain for the Division of Information Studies at Nanyang Technology University, Singapore. The taxonomy was built by using the Dewey Decimal Classification, the Information Science Taxonomy, two information systems taxonomies, and three thesauri (ASIS&T, LISA, and ERIC). Findings - Classification schemes and thesauri were found to be helpful in creating the structure and categories related to the subject facet of the taxonomy, but organizational community sources had to be consulted and several methods had to be employed. The organizational activities and stakeholders' needs had to be identified to determine the objectives, facets, and the subject coverage of the taxonomy. Main categories were determined by identifying the stakeholders' interests and consulting organizational community sources and domain taxonomies. Category terms were selected from terminologies of classification schemes, domain taxonomies, and thesauri against the stakeholders' interests. Hierarchical structures of the main categories were constructed in line with the stakeholders' perspectives and the navigational role taking advantage of structures/term relationships from classification schemes and thesauri. Categories were determined in line with the concepts and the hierarchical levels. Format of categories were uniformed according to a commonly used standard. The consistency principle was employed to make the taxonomy structure and categories neater. Validation of the draft taxonomy through consultations with the stakeholders further refined the taxonomy. Originality/value - No similar study could be traced in the literature. The steps and methods used in the taxonomy development, and the information studies taxonomy itself, will be helpful for library and information schools and other similar organizations in their effort to develop taxonomies for organizing content and aiding navigation on organizational sites.

Abstract

In the information age, a common problem for employees is not lack of resources but rather how to sift through multiple resources, both electronic and interpersonal, to retrieve and locate true expert knowledge. The main objective of this study is hence to explore employees' simultaneous usage of both resources and to identify situations where employees showed a clear preference of interpersonal resources over electronic ones, and where employees found these two resources (a) (ir)replaceable and (b) complementary. Both qualitative interview data and quantitative social-network data were collected from a university-affiliated community educational office. Data analysis showed that (a) social relationships were crucial for seeking and gaining actual access to needed knowledge; (b) employees were task-driven in knowledge seeking and obtained different types of knowledge depending on availability; and (c) the choice between interpersonal and electronic resources was determined by the characteristics of the knowledge sought as well as such contextual factors as time, cost, and location. Additional interviews from other study contexts validated most of our findings, except those that require collection of complete social-network data. The article ends with a discussion on how organizations can better leverage their investment in human and technical resources to facilitate knowledge seeking.

Abstract

Many US companies are looking to business processing reengineering (BPR) - a process of redesign that is dramatic, company-wide, and often information technology oriented - in order to compete in the global marketplace. Given the scope and importance of BPR work, it is critical that there should be some objective measures applied to determining which possible changes shouldbe made in business' processes. Computer simulation technology is well suited to this design assessment role. Use of simulation, entails varieties of data collection that go beyond the information generally gathered in a BPR analysis. Once in use, simulation models encourage a culture of measurement that supports continuous process improvement. Recommends explicit attention to and management of the modelling tasks: data collection and organization; simulation of component designs, and integration of component simulation results

Abstract

Autonomy of operations combined with decentralized management of data gives rise to a number of hetegrogeneous databases or information systems within an enterprise. These systems are often incompatible in structure as well as content and, hence, difficult to integrate. Depsite heterogeneity, the unity of overall purpose within a common application domain, nevertheless, provides a degree of semantic similarity that manifests itself in the form of similar data structures and common usage patterns of existing information systems. This article introduces a conceptual integration approach that exploits the similarity in metalevel information in existing systems and performs 'metadata mining' on database objects to discover a set of concepts that serve as a domain abstraction and provide a conceptual layer is further uitlized by an information reengineering framework that customizes and packages information to reflect the unique needs of differnt user groups within the application domain. The architecture of the information reengineering framework is based on an object-oriented model that represents the discovered concepts as customized application objects for each distinct user group
