基于Linked Open Data的Web服务语义互操作关键技术

With the Web Service Relation Network as the core,and based on the open public Ontology such as Linked Open Data(LOD), this project will study the key technology of the Services semantic interoperability of Service computing to solve the problem of the semantics sharing of Service interoperability. Then this project establish a multi-dimensional Ontology-based Semantic Service Model, in which Service semantic is descripted from various aspects, dimensions and levels,to eliminate the semantic fuzziness and ambiguity of the Web Services and promote the intelligence of Web Services organization. In order to solve the problem of the low mark accuracy of the traditional Web Service caused by the limited of knowledge representation and the dependence of local Ontology, the semantic enhancement method,based on the combination of open public Ontology and field local Ontology,will be studied to coordinate the contradiction between the unity and diversity of the Service semantics to achieve semantic interoperability of Services.At last,on the fundation of Service semantic relation network,analysis methods for complex social network will be used to construct a hierarchical, multi-regional Service network community structure,and to create a Web Service reasoning model of syntax and semantics of conversion.On this basis, Service-oriented selection and recommended conflict resolution strategies will be designed, and hybrid reasoning method based on the combination of Ontology and rules will be served as the utility to realize the intelligent knowledge-based World Wide Web Service discovery and composition.

以服务网络(Web Service Relation Network,SN)为核心，基于Linked Open Data(LOD)等多个开放共享本体，研究Web服务计算中的语义互操作关键问题。首先，研究基于多本体的多维度语义服务模型，刻画服务多维度、多层次的语义特征，消除服务语义的模糊性和歧义性，实现服务语义层面的组织与管理。其次，设计开放共享本体与本地局部本体相结合的服务语义增强方法，协调服务语义的统一性与多样性之间的矛盾,以解决传统服务标注中对特定本体依赖性强、知识表示有限而导致的标注结果准确性低，以及不同本体标注结果之间存在语义歧义，难以实现语义互操作的问题。最后，以社会网络与复杂网络的理论与方法为指导，构建层次化、多区域的服务社区结构，设计基于规则的服务选择和推荐冲突解决策略，利用本体和规则相结合的混合推理方法,实现服务的语义互操作。
