摘　　要：随着语义网技术的快速发展和OGC服务的深入应用,地表覆盖Web服务组合成为地表覆盖领域的关键挑战之一。近年来,知识建模在解决Web服务组合方面取得了重要的研究进展,但尚缺少面向地表覆盖服务组合领域的知识模型,进而对地表覆盖服务组合的准确性和智能性造成一定影响。为此,本文提出了一个面向地表覆盖服务组合的知识建模与推理方法,构建了地表覆盖服务本体(land cover service ontology,LCSOnt),并实现了基于数据预处理规则和服务链组合规则的前向链接服务组合推理机制。以地表覆盖变化检测为例,使用LCSOnt对变化检测任务、数据以及服务进行实例化,构建了变化检测服务组合知识规则。最后通过规则推理实现了变化检测服务链的生成,证明了该方法的有效性和可行性。With the rapid development of semantic web technology and the in-depth application of OGC service,the land coverage web service composition has become one of the key challenges in the field of land coverage.In recent years,knowledge modeling has made important research progress in solving Web service composition,but there is still a lack of knowledge models for the domain of land coverage service composition,which in turn has some impact on the accuracy and intelligence of land coverage service composition.To this end,this paper proposes a knowledge modeling and reasoning approach for land coverage service composition,constructs a land coverage service ontology(LCSOnt),and implements a forward-linked service composition reasoning mechanism based on data preprocessing rules and service chain composition rules.Taking the land coverage change detection as an example,the change detection task,data and services are instantiated using LCSOnt,and the change detection service composition knowledge rules are constructed.Finally,the generation of change detection service chains is realized by rule reasoning,and the effectiveness and feasibility of the method are proved.
