    • 摘要: 针对宁夏地区回汉混居而引发的多节日问题,以及现有事件本体模型不能充分表达和节日相关的人、事、物等之间丰富的语义关系等问题。本文提出了FEOM(Festival-oriented Event Ontology Model,面向节日的事件本体模型)和宁夏地区回族传统节日领域本体的构建方法 -六步法,在此基础之上,构建了宁夏地区回族传统节日领域本体。该领域本体的构建不仅证实了FEOM的合理性和六步法的可行性,也体现了本体技术广泛的应用前景。

    • 摘要: 本文介绍了RDF标准的基本概念、发展演化、核心内容及其在元数据描述中应用的4个领域:DC、Marc、OWL和RSS.通过研究应用的对比给出了结论:RDF具有易控制性、包容性、机器间互操作性、易综合性的优点.但是RDF在日常应用有些复杂,设计者不仅需要定义对象和属性,而且需要定义复杂的陈述.而互联网上的元数据描述需要更为简单而且可靠的解决方案.%RDF concept, evolution and core content were described in this article. The 4 kind application of RDF in metadata description were also described in this article, such as DC, Marc, OWL and RSS. The conclusion is: RDF is a manageable and compatible recommendation on metadata description with a good Interoperability. But RDF is somewhat complex that designers must define the objects, properties and complicated statements. The simpler and more reliable resolution will be needed on Internet metadata description.

    • 摘要: WEB本体语言(OWL)是一种用于对本体进行语义描述的语言,不仅提供强大的语义表达能力,而且能够表达机器可以理解的内容。关系数据库在存储与管理大规模数据方面相应技术比较成熟。针对该情况,结合两者的优势,提出一种基于关系数据库存储 OWL 本体的存锗模式,主要针对本体类的存储模式的设计思想和关键接口实现技术进行叙述。案例研究表明,所设计的类可以有效的实现关系数据库和OWL本体类之间的数据转换。%OWL is a language that depicts semantics of ontology. It does not only provide the strong semantic expression, but presents content that computer can be understandable. In the area of storage and managing mega data , the relevant techniques of relational database are natured. In this paper, the advantages of both are fully taken. It puts forward a storage model of relational database storing OWL ontology. This paper mainly gives design ideas and key interface technologies of the OWL Class storage model. Case studies show that classes that we design can effectively achieve data conversion relationship between the database and the OWL ontology Class.

    • 摘要: The classic recommendation system is mainly based on the users for the project evaluation or the keywords similarity between the user and the item for recommendation, there is a low degree of information structure, lack of semantic and other issues. To solve these problems, this paper proposes an ontology-based recommender system model. This model uses OWL language describe the user and project information by introducing ontology to bear more semantic information and improve the degree of information structure. In the recommendation process, the results of analyzing user behavior information by rules is considered for improve the quality of recommendation. Experimental results show that the model has better effect in degree of information structure and semantics. It can effectively improve the recall and precision rates by using this model for recommendation.%经典推荐系统主要根据用户对项目的评价或者用户与项目之间的关键字相似度进行推荐,存在信息结构化程度低、语义缺乏、信息利用不充分等问题。为此,提出一种基于本体的推荐系统模型。将本体引入到推荐系统中,使用OWL语言对用户和项目信息进行描述,使用户和项目具有语义信息的同时,提高信息的结构化描述水平。在推荐过程中,通过规则分析用户行为信息并综合考虑以提高模型的推荐质量。实验结果证明,与传统推荐模型相比,该模型在信息结构化水平、语义描述等方面具有优势。采用该模型为用户推荐项目能够有效提高推荐的召回率和准确率。

    • 摘要: Aiming at the problem that most existing QoS models focus on generic QoS properties while ignore domain-specific ones, which are also of great use in evaluating the QoS level of a Web service,propose a new Web quality of service model,which introduces a specific field service quality attributes,the model consists of three sub-models. A quality of service and the target object tree is estab-lished,then get the formation of the tree of corresponding service weight. This model is not only adapted for a single Web service request, but also used for a combination of multiple service requests. An example is used to illustrate the correctness and availability of this model.%针对现有的Web服务质量模型主要考虑的都是通用的服务质量属性,没有考虑特定的Web服务属性在评价中的作用,提出了一个新的Web服务质量模型,它引入了一个特定领域的服务质量属性,该模型包括三个子模型。模型中建立了相关的服务质量树和目标对象树,通过量化指标子模型对目标对象进行量化,形成相应的服务权重树。该模型既可适应用于单个的Web服务请求,也可以用于多个服务组合而成的请求。通过一个应用实例验证了模型的正确性和可用性。

    • 摘要: In Traditional Chinese Medicine (TCM) domain, knowledge modeling for TCM syndromes serves as the foundation for the construction of knowledge bases and clinical decision-support systems. The complexity and fuzziness of TCM syndrome knowledge causes difficulties for knowledge modeling. Web Ontology Language is a core technology for the Semantic Web.

    • 摘要: 作为智能电网标准体系中的重要构成部分,IEC 61850与IEC 61970标准之间存在着不兼容、不和谐等问题,这阻碍了智能电网源端维护技术的实现.提出了基于本体映射与规则推理的智能电网信息集成技术.基于Protege分别构建了SCL与CIM的本体模型,并通过OWL语言实现了两个模型的形式化描述.然后利用SWRL语言表达语义模型之间的映射规则,解决了OWL语言推理能力不足的缺陷.将本体模型与SWRL规则转换为专家系统知识库,并利用CLIPS实现本体推理.算例中完成了从SCL到CIM/RDF的变换,所生成的文件符合IEC 61970标准,证明了方案的可行性.%IEC 61850 and IEC 61970 are important parts of the smart grid standard system, but there exists incompatible and disharmonious problems between them, which hinder the realization of the source-end maintenance technology. Based on ontology mapping and rule reasoning, this paper proposes a novel model mapping techniques. First, this paper builds the ontology models of SCL and CIM based on Protege, and consequently realizes the formal description of the models by OWL. Subsequently, this paper expresses the mapping rules between the two semantic models by SWRL, which makes up for the deficiency of the reasoning ability of OWL. Finally, by converting the ontologies and the SWRL rules to the Expert System knowledge base, this paper exploits CLIPS to realize the ontology reasoning. In the study case, this paper completes the conversion from an SCL file to a CIM/RDF one. The generated CIM/RDF file measures up to the IEC 61970 standard, which demonstrates the effectiveness of the proposed scheme.

    • 摘要: 针对基于角色的访问控制(RBAC)模型对权限实体的刻画能力不足,提出了带权限层次扩展的RBAC模型.为结合本体在知识表示和推理方面的优势,提出了该模型的本体表示和实现方法.该方法使用Web本体语言(OWL)表示该扩展模型,借助语义Web规则语言(SWRL)定义模型中应用逻辑规则,隐式授权知识经规则推理获得.在此基础上,通过SPARQL协议和RDF查询语言(SPARQL)查询命令生成显式和隐式授权视图,实现系统安全状态分析.最后,给出了具体应用示例,表明该方法的可行性.%Role Based Access Control ( RBAC) has deficiency in characterizing permissions, so an extended RBAC model with permission hierarchy was presented. To utilize advantages of ontology in knowledge representing and reasoning, an ontology based representation and realization method of the extended model was proposed. Web Ontology Language (OWL) was used to formalize the ontology of this model, and some specific reasoning rules in the model were defined by Semantic Web Rule Language (SWRL). Implicit knowledge about authorization was derived through rule based reasoning. Based on this, explicit and implicit authorization views were generated for security analysis through the SPARQL Protocol and RDF Query Language (SPARQL).Finally,a case study was introduced to show the feasibility of the method.
