This paper introduced a formal framework , within which the semantic models usually used in electronic product design are analyzed . then , this paper presented an interaction mechanism among different semantic models by signal matching based on the formal framework 基于对语义模型交互中信号构成的分析和统一的形式化表示,本文提出一种基于信号映射的语义交互机制,并给出了实现框架。
This framework is composed of semantic modeling of certain domain , semantic description of resources , extension search of semantic model , and etc . this paper emphasize on rdf inference mechanism , which is the fundamental of sematic retrieval 该框架主要由特定领域的语义建模、信息资源的语义描述、语义模型扩展查询等部分组成。 rdf的推理机制是本文研究的重点,也是进行语义检索的理论基础。
Semantic model definition language a set of instructions that describe layout and query information for reports created in report builder . smdl is composed of xml elements that conform to an xml grammar created for the reporting services report builder component 例如, sql server数据库的数据连接由数据库的名称、数据库所驻留的服务器的位置、用于访问该服务器的网络信息以及用户id和密码组成。
Multiplicity , dependency , and inheritance . aiming at the disadvantage of this model in expressing the integrity of objects , in this dissertation , we organize the part - whole semantic model into five characteristic dimensions : exclusiveness 为了形式化地描述部分-整体语义模型, m . halper等人将oodb中的部分-整体语义模型组织为四个特征域:排斥性特征域、重复度特征域、依赖性特征域和继承性特征域。
The extract process have three steps : constructing echg of java system from java profile , extracting system ' s lexical relational model by scanning source code and analyzing the polymorphism calling location , constructing the semantic model by rule - based model mapping of lexical model 抽取过程有三个阶段:构造系统的echg ,扫描程序的源代码和多态点分析得到系统的词法层次模型,通过基于规则的推理转换词法模型为语义模型。
He implements the system in three layers : first , in the semantic definition layer , it establishes the data structure construct and semantic model ; second , in the data processing layer , it integrates the financial data and the other business data into the convenience analysis form according to etl ( extract transform loading ) action ; finally , in the presentation layer it implements slice , rotation and drill down / up action . so it meets the requirement of financial analysis and financial management for enterprise 在语义定义层完成企业数据结构的搭建和语义建模工作;在数据处理层通过一系列的etl (析取、转换、加载)操作,实现了对企业财务数据及相关业务数据的有效整合,并且最终形成便于分析的多维数据体系:进而在数据表现层实现了对目标数据的切片、旋转、钻取等多种手段的分析操作,以满足企业财务分析、财务管理以及决策支持工作的需要。
This thesis studies the principle of ais , the types of its system structure and the key factors which affect its evolution , explains the necessity and feasibility of ais based on event approach , emphasizes how to use the entity - relation approach and the real ( r is for " resource " , e for " event " , a for " agent " , l for " location " ) semantic model to design the integrate event - driven database and expects intelligent decision support system ( idss ) , the application of data warehousing and olap technology in decision support system ( dss ) 文章的研究思路是:从会计信息系统体系结构的角度,研究系统体系结构的类型及其演变的主要影响因素。论述了基于事项会计的会计信息系统的现实必要性和技术可行性;重点研究了现代信息技术环境下,基于事项会计的会计信息系统体系结构、如何运用e - r概念模型与real业务过程语义模型分析和设计集成业务数据库、基于事项会计的会计信息系统原理和结构;并展望了数据仓库和olap联机分析处理技术在决策支持系统dss中的应用,即基于企业数据仓库的智能决策支持系统( idss )前沿研究。
In this paper , the author studies the abstraction of product data information based on step neutral files . the data information of 3 - d product is extracted from the step neutral file according to the semantic model of step / ap203 schema . the data is handled by using data mining principle and topology way searching methord 本论文主要研究基于step中性文件的产品数据信息之提取,其机理是按step ap203语义模型从step中性文件中提取三维产品模型的数据信息,利用数据挖掘原理和拓扑路径检索的方法进行数据处理,获得所需的数据,由图形显示模块利用java3dapi技术实现三维产品数据模型的重建。

We have brought forward a new workflow model - extended xinpai - drived workflow computing model based on xinpai - drived workflow computing model , integrated with the workflow standard semantic model described by workflow process definition language ( wpdl ) and established by workflow management coalition ( wfmc ) . then we developed a j2ee based workflow management system prototype - j2ee - wfms basing on that model 我们在继承信牌驱动式工作流计算模型的基础上,结合工作流管理联盟( wfmc )所制定的用工作流过程定义语言( wpdl )描述的工作流标准语义模型,又提出了一个新的工作流模型? ?扩展的信牌驱动式工作流计算模型。
