中文摘要：

在数字地名词典中恰当地表达和管理地名的类型知识，有助于数字地名词典快速、有效地处理地名相关查询。为此，该文首先从数字地名词典的应用需求出发，分析类型在数字地名词典中的作用，进而设计一个地名类型本体模型。该模型表达了地名类型之间的继承关系以及对空间关系的约束。在本体模型基础上，提出了相应的查询处理策略并进行了系统实现。

英文摘要：

Digital gazetteers provide information about place names and corresponding services. Types of place names play an important role in digital gazetteers. With the representation and management of type information,a gazetteer would become more effective so that it can bridge the semantic gap between user requirements and the provided functions. According to the requirements of digital gazetteers associated with type information,an ontological model of type information in digital gazetteers is developed. The model explicitly represents the type hierarchy and constraints on spatial relationships. Following the ontological model, several execution strategies, such as measuring fitness, are designed to support queries about the digital gazetteer. A prototype software tool implements the strategies and demonstrates the feasibility of the proposed approaches.
