河道健康管理本体模型构建与数据存储方法设计

Ontology Model Construction and Data Storage Method Design for River Health Management

摘要:

河道的有效管理是维持河道健康生态状况的前提条件。针对河道健康数据存在的跨部门管理、存储效率低下、语义信息被忽略等问题，提出了一种基于本体的河道健康数据存储方法。构建了河道健康领域的本体模型，设计了基于Neo4j图数据库的河道健康数据存储方法。以上海市宝山区河道为例，开发了河道健康可视化原型系统，实现了河道健康本体数据在概念、关系、属性和实例的存储与查询。设计了2种不同本体存储方式查询效率的对比试验，验证了本文方法的有效性和可行性。

Abstract:

Effective management of river channels is a prerequisite for maintaining the healthy ecological condition of river channels. An ontology-based method for storing multi-source river health data is proposed to address the problems of cross-sector management， inefficient storage， and semantic information ignored in river health data. An ontology model of river health domain is constructed， and a storage method of river health data based on Neo4j graph database is designed. Taking the river in Baoshan District， Shanghai as an example， a river health visualization prototype system is developed， which successfully achieves the storage and query of river health ontology data in concepts， relations， attributes and instances. A comparison test of the query efficiency of two different ontology storage methods is designed to validate the effectiveness and feasibility of the method proposed in this paper.
