基于语义的地理概念范例构造方法

Semantic-Based Methodology for Creation of Exemplars of Geographical Concepts

  • 摘要: 跨领域地理信息的语义共享的实现依赖于对地理概念的明确理解,而由于文字的模糊性,仅从地理概念的文字描述或定义来理解往往会有一定歧义。从认知原理看,地理概念的形成更多是对其外延进行归纳,并在大脑中构建出概念范例来完成。探索了一种在地理信息领域中构造地理概念范例的方法,即通过在概念文字描述中提取确定概念范畴及外延的本体属性,通过外延和实体属性来选择实例作为表达概念显著特征的范例。通过两个构建范例的案例验证了该方法的有效性。

     

    Abstract: Geo-semantic sharing in a cross-domain depends on clarifying geographical concepts. Literalvagueness may lead to ambiguity of apprehension of a concept from its text definition or description. From the view of cognitive psychology, a geographical concept is formed from deduction of extensional entities of the concept and by creation of its exemplars from its extension. Therefore, this paper pre-sents a methodology of creation of exemplars of geographical concepts in the domain of geographical information, where, ontological attributes of a concept are drawn from deducing text descriptions into a set of terms or semantic units and characterized by categorization of the extension of the concept. The extensional entities and entity attributes are exploited to generate or determine the exemplars among geographical entities in terms of notable features. This study indicates the availability of the proposed methodology by presenting two methodological paradigms of creating exemplars of geographical concepts.
