چکیده

Integrated Coastal Zone Management (ICZM) is an application area of increasing importance, requiring much data, information and knowledge. The scale of this resource is acknowledged at an international level, and is known to be ever growing. Among other factors, the global repository of coastal data and information is known to be fragmented, is of different formats and occurs at various scales. Metadata, where it exists, is widely recognised as a valuable method of navigation for this resource. This paper demonstrates the successful use of an expert system to provide intelligent access to a set of coastal metadata (on the Fal Estuary, southwest Cornwall, UK), whilst taking a holistic approach. This approach is central to ICZM and is necessary when having to deal with the attendant multiple disciplines, scales and technologies, and when providing an integrated solution to managing coastal data, information and knowledge. Practically, the expert system employs the Dempster-Shafer theory of evidence and the associated concepts of ignorance and integration to tackle the uncertainty and complexity inherent in the holistic paradigm.
