Organisations make use of a variety of knowledge management systems (KMS) in order to facilitate the creation, storage, transfer and reuse of organisational knowledge. Metadata is used to describe knowledge by its attributes and to provide the context, quality, condition or other characteristics of knowledge assets. This thesis explores the way in which metadata is being used in KMS. It provides an analysis of the types of metadata used for the descriptIon of knowledge documents at the semantic level and complements other research on the evaluation of KMS by focusing on the use of metadata, adopting a user perspective. The empirical work was carried out through case study research in two highly knowledge-intensive companies, a motorsport engineering company and a pharmaceutical company. Data collection tools included field visits, documentation, surveys and interviews. The findings demonstrate the level of users' satisfaction with the KMS and metadata and their readiness to create metadata when contributing a knowledge document to the KMS. Demographic factors, such as gender, age, qualifications, and years working with the company, are analysed in conjunction with attitudes towards the KMS and metadata The two metadata schemes used in each company are mapped semantically to the widely used Dublin Core Metadata Element Set (DCMI), in order to identify good practice in designing a metadata scheme for a KMS From the mapping, the basis of a metadata framework is created, intended to be used as a checklist for the development of comprehensive metadata schemes for the description of knowledge documents. The metadata management processes of the two companies are analysed to propose guidelines for the development of a metadata management strategy.

Information technology (IT) has been widely used in organizational knowledge management initiatives, and organizations continue to invest in IT expecting that its use will improve knowledge workers' productivity and organizational performance. -- Knowledge management systems (KMS) are information technology applications designed for knowledge management. The pervasive use of KMS in organizations has raised crucial concerns about the use and value of KMS, which can be expressed as two key questions: - What are the key determinants to the users' acceptance and use of KMS in their daily work? - What is the actual role of KMS in the support of knowledge management? -- For this thesis, empirical research was conducted on KMS success in organizations from a social capital perspective, aiming to tackle these critical questions. Based on a review of existing studies on knowledge management and information systems success, two KMS research models are developed, namely a Socio-Technical System Framework of KMS and an Adaptive Structuration Theory (AST)-based KMS Success Model. The socio-technical framework model of KMS sets out the main KMS components and the interrelationships between these components, presenting a systematic view of KMS in organizations. The AST-based KMS success model represents dynamic and evolutionary KMS in organizations, proposing a system-to-value chain of KMS success linking KMS use to social capital, and to intellectual capital. In the research, the two models have been operationalized; consequently, a set of theoretical hypotheses has been derived. -- A set of survey instruments has been developed or adapted for the study. A preliminary study is used to test, adapt, and modify the new instruments. A web-based cross-sectional survey is conducted, and a sample of 362 knowledge workers from a variety of organizations enables the researcher to further validate the new instruments, assess the research models, and test the hypothesized relationships through structural equation modeling techniques (PLS and LISREL). The results provide clear evidence of the newly developed instruments' reliability, validity, and general applicability, and demonstrate that the research models have good explanatory power for the variances in the KMS use and social capital constructs. Significantly, the study has confirmed that KMS does have the expected significant positive effects on individual social capital development, a critical social infrastructure for knowledge management. The significant positive impacts of KMS use on three dimensions of social capital-structural, relational, and cognitive dimension-have been assessed, and significant findings have been achieved. Moreover, a set of potential critical determinants to users' acceptance and use of KMS has also been assessed in the study. The results have demonstrated the different levels of impacts of these factors on the users' acceptance and use of KMS. -- Based on the research results, recommendations are made for managers, and implications have been drawn for future research. -- Keywords: Knowledge Management Systems (KMS), KMS success measurement, performance-related use of KMS, structural equation modeling, social capital. / Mode of access: World Wide Web. / ix, 277, A23 p. ill

The emergence of Web 2.0 tools has transformed the operation of Knowledge Management (KM) practices in the academic libraries. This study has investigated the application of Web 2.0 tools to enhance KM practices in academic libraries in Tanzania. Eight out of twelve academic libraries located in public universities in Tanzania were purposively selected in this study. The study included two categories of respondents: ordinary library staff and senior library staff (directors, heads of libraries, library managers, and Information and Technology (IT) specialists in the library etc). The findings of the study were determined after applying methodological triangulation within quantitative and qualitative research contexts. This included the use of questionnaires, semi-structured interviews and observations. In the first instance, questionnaires were used to collect data from 278 library staff selected using systematic sampling technique. Interviewing targeted 69 senior library staff was done using purposive sampling technique. In total, 254 (91.4%) ordinary library staff completed the questionnaire; while 57 (82.6%) senior librarians were interviewed. The study findings have indicated the low level of KM application in academic libraries. Muhimbili University of Health and Allied Science (MUHAS) Library showed the strongest application of KM practices, followed by State University of Zanzibar (SUZA) Library. Lack of KM enablers in academic libraries was indicated as one of the significant challenges that hinder the application of KM practices in academic libraries. It was noted that most of the academic libraries visited had websites. On the other hand, the majority of respondents acknowledged that they had personal accounts of the various Web 2.0 tools. The study findings imply that most library staff had some level of experience with a variety of Web 2.0 tools. It was further established that despite the high level of familiarity and use of Web 2.0 tools, respondents were not frequent users of their library websites. The study findings have also indicated a low level of access and use of Web 2.0 tools within academic libraries. Mzumbe University (MU) and SUZA Libraries were the main users of Web 2.0 tools; followed by University of Dar-es-Salaam (UDSM) Library. Knowledge Management System (KMS) Success Model was employed to investigate factors that affect the application of Web 2.0 tools to enhance KM practices. The study findings have demonstrated that the KMS Success Model is suitable for guiding the understanding of the contributing factors with respect to library staff‟s intention to reuse Web 2.0 tools. The study findings supported the KMS Success Model well, whereby seven of the twelve hypothesised relationships were found to be significant. The study recommends that academic libraries in Tanzania should promote and integrate KM practices in their daily operations as well as the use of KM enablers such as; reliable budget, Web 2.0 tools, reliable power supply, internet connectivity availability and adequate ICTs infrastructure. / Information Science / D.
