【摘要】：鉴于当前缺乏针对岛礁及其资源环境领域知识的建模,导致要素语义表达中的模糊性和差异性,难以满足相关空间数据组织与共享的需求。该文在深入分析岛礁及其资源环境相关领域知识的基础上,引入地理本体理论与方法,充分考虑各要素的概念与关系特征,通过定义类、属性、关系和约束条件,实现对要素概念及关系的形式化表达,以完成岛礁本体的构建;同时利用四叉树编码实现岛礁与空间数据间的映射关联,以支持岛礁空间数据的一体化集成与管理;最后分别以永兴岛与海浪数据为例说明该本体规范化表述,并以岛礁信息检索为例验证其有效性。结果表明该本体能较好表达岛礁及其资源环境要素的相关知识,具有一定的实用价值。
[Abstract]:In view of the lack of modeling of knowledge in the field of islands and reefs and their resources and environment at present, it is difficult to meet the needs of spatial data organization and sharing because of the ambiguity and difference in the semantic representation of elements. On the basis of in-depth analysis of the knowledge of islands and reefs and their related fields of resources and environment, this paper introduces the theory and method of geographical ontology, fully considers the concepts and relational characteristics of each element, and defines classes, attributes, relationships and constraints. The formal expression of the concept and relation of the elements is realized to complete the construction of the reef ontology, and the mapping association between the reef and the spatial data is realized by using quadtree coding to support the integration and management of the spatial data of the island and reef. Finally, Yongxing Island and Ocean Wave data are taken as examples to illustrate the Noumenon canonical representation, and the information retrieval of islands and reefs is taken as an example to verify its validity. The results show that the Noumenon can express the relevant knowledge of the islands and reefs and their resources and environment elements, and has certain practical value.
