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

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。

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.
