摘要：In analogy to spatial and temporal reference systems, semantic reference systems have been proposed to support interoperation between information communities. Such reference systems provide the structure for specifying intended interpretations of communities' vocabularies and the functionality of translating expressions used by one community to those used by another. First attempts towards designing semantic reference systems have been made and few prototypical implementations examined the notion for information communities in the geospatial domain. In addition to ambiguous, general and open-textured expressions that are applied to define data models, many geospatial concepts are vague in nature and geospatial information relies on error-prone measurements. Not all these aspects have yet been considered in reference systems. The work presented in this paper analyses the requirements, which semantic reference systems need to meet, in order to account for the varying facets of uncertainty. The facets are categorised and taxonomically structured. Design requirements are derived for each category. Possibilities of satisfying these requirements are outlined. The analysis defines a basis for developing semantic reference systems, which account for uncertainties underlying geospatial information
