【摘要】：作为新兴的空间信息技术之一，地理信息系统（GIS）的应用领域越来越广泛，涉及国土资源、城市规划、智能交通等多行业领域。但由于存在数据的多源异构、空间数据共享及语义互操作等问题，GIS应用仍被认为是信息孤岛。随着计算机和人工智能的发展，本体被引入其中用于知识的获取、表达、共享及重用，成为领域内的研究热点。本体能够描述语义和知识层次的概念模型，它不仅可以以语义编码的方式将空间数据描述为计算机更易理解的格式，而且可以集成不同格式的多源空间数据进行信息查询。近年来，本体作为“共享概念模型的明确的形式化规范说明”引入到GIS领域并迅速发展起来，形成地理本体。本文通过研究本体和地理本体的概念及其相关理论，将其应用在矿产资源领域，对地理本体的构建及查询进行了研究。基于本体的矿产资源空间信息分类体系是对原始矿产资源空间信息的抽象概括后形成的群体共识的概念模型，是一个满足语义共享要求的空间概念模型，是实现空间信息共享集成的基础。本文主要研究工作包括：（1）分析了本体及地理本体的定义和内涵，确定了表达本体所使用的形式化描述语言OWL、本体的构建方法“七步法”以及本体的构建工具Protégé，，为下一步地理本体的构建奠定基础。（2）以青海省东昆仑成矿带地质空间数据为例，对矿产资源领域内的相关地理概念和关系进行抽取，借助斯坦福大学开发的本体建模工具Protégé，以OWL语言构建了一个矿产资源空间信息的分类体系。由此可将该领域内默认和隐含的语义信息显示和形式化地表达出来，并为矿产资源空间信息的共享提供了理论依据，实现不同个人、部门之间对矿产资源空间信息知识的共同理解。（3）以构建的矿产资源地理本体为基础，应用惠普公司开发的Jena包及 SPARQL语言实现了基于地理本体的语义和空间关系的查询方法，从而打破原有的基于数据和元数据的空间信息查询方法，提供给普通大众所需的智能化GIS查询方式。
[Abstract]:As one of the new spatial information technologies, GIS (Geographic Information system) is more and more widely used in land and resources, urban planning, intelligent transportation and other fields. However, because of the heterogeneity of data, spatial data sharing and semantic interoperability are still considered as isolated information islands. With the development of computer and artificial intelligence, ontology has been introduced into it for knowledge acquisition, expression, sharing and reuse. Ontology can describe the conceptual model of semantic and knowledge levels. It can not only describe spatial data as a more easily understood format by semantic coding, but also integrate multi-source spatial data in different formats for information query. In recent years, ontology has been introduced into the field of GIS as a "explicit formal specification of shared conceptual model" and developed rapidly to form geographical ontology. In this paper, the concepts of ontology and geographical ontology and their related theories are studied, and the construction and query of geographical ontology are studied in the field of mineral resources. The classification system of mineral resources spatial information based on ontology is a conceptual model of group consensus formed by abstract generalization of spatial information of original mineral resources. It is a spatial conceptual model that meets the requirement of semantic sharing. It is the foundation of spatial information sharing integration. The main research work of this paper includes: (1) the definition and connotation of ontology and geographical ontology are analyzed, and the formal description language owl, the method of ontology construction "seven steps" and the tool of ontology construction, Prot 茅 g 茅, are determined, which lays the foundation for the next step of constructing geographical ontology. Taking the geological spatial data of the East Kunlun metallogenic belt in Qinghai Province as an example, the relevant geographical concepts and relationships in the field of mineral resources are extracted. With the help of Prot 茅 g 茅, an ontology modeling tool developed by Stanford University, a classification system of mineral resources spatial information is constructed by using OWL language. Thus, the default and implied semantic information in this field can be displayed and formalized, which provides a theoretical basis for the sharing of spatial information of mineral resources and realizes different individuals. The common understanding of spatial information knowledge of mineral resources among departments. 3) based on the geographical ontology of mineral resources, the Jena package developed by Hewlett-Packard and The SPARQL language implements the query method based on the semantic and spatial relation of geographical ontology, which breaks the original spatial information query method based on data and metadata, and provides the intelligent GIS query method needed by the general public.
