- ItemA semantic framework for the delivery of e-government information and services : the case of New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy (Ph.D.) in Information Systems at Massey University, Palmerston North, New Zealand(Massey University, 2011) Zhou, JiaThe motivation for the research was to add to the body of knowledge associated with the design and construction of a semantic framework that would serve the needs of the e-government community. The purpose of the thesis was to investigate whether a semantic framework could be described and created in order to establish a foundation reference model for the subsequent delivery of governmental information and services across the Internet. New Zealand Parliament and local government council were used as a representative domain, where the research question could be addressed and from which general inferences could be made about the delivery of government information across the Internet. An embedded case study research methodology was employed in this research. The process began by constructing a semantic framework which was then instantiated with information from New Zealand government agencies. Information was then retrieved from the ontology using a query-driven web browser interface. The resulting artefact was evaluated using a triangulated mixed method approach involving expert judgement, simulation analysis and metrics based on the OntoQA method. Two key conclusions can be made from this research. Firstly, the results of the comprehensive evaluation regime supported the view that the prototype semantic framework constructed to support the delivery of New Zealand governmental information to users in both a stand-alone environment or via a portal, was found to be effective and efficient. Given the similarity of the format and structure of New Zealand?s national and local government agencies to jurisdictions overseas there is optimism that the framework could be imported into other e-government initiatives. Secondly, the processes associated with the design and development of the semantic framework and browser interface were carefully monitored and recorded in accordance with design science research practice. Developers and researchers of e-government would find the results of this research activity, both from an e-government or design science research perspective, informative and useful.
- ItemValidation of the CIDOC CRM using both extended graphical and category theory representations : includes two New Zealand case studies : a thesis presented in partial fulfilment of the requirements for the degree of Master of Business Studies in Information Systems at Massey University, Palmerston North, New Zealand(Massey University, 2004) Zhou, JiaThere is considerable interest in the use of the Internet to retrieve and integrate multimedia information from centres of cultural heritage such as museums and art galleries. The ultimate desire of most devotees of cultural matters is to have universal access, through a single portal, to detailed information from sites throughout the world. This level of interoperability is not an easy task both technically and culturally. To provide an avenue where some of the technical problems of accessing information from a huge range of unique database environments can be resolved, a semantic conceptual reference model (CRM) was proposed by The International Committee for Documentation of the International Council of Museums (ICOM-CIDOC). The model provides definitions and a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation. It is intended to provide a common and extensible semantic framework to which any cultural heritage information can be mapped. In this research two methods are proposed and developed to support the validation of the Conceptual Reference Model. The methodologies, one graphical and the other based on category theory, are used to replicate three published international validation activities and two new validations based on information supplied by two New Zealand heritage sites. This report also includes a literature review describing the main ideas and structures that form the basis of the CRM.
