摘要
面向相同的信息空间,异型信息系统采用不同的信息域划分标准及信息描述方法,导致对同一实体的描述信息在逻辑结构和语义表述方面存在差异,妨碍了系统间信息的有效共享。因此,提出了一种基于概念逻辑树的异构信息描述模型,采用树型结构对不同系统的概念集进行通用结构化组织,显式地描述概念之间的逻辑层次和语义关系,实现异构实体描述信息的一致化表示;采用类XML语言和关系矩阵对表示信息进行集中组织和存储,构建了基于统一信息空间的异构信息共享框架。理论分析表明,该模型能够有效表示异构信息基于逻辑及语义的层次结构,有利于实现异构信息基于内容及语义的融合与共享。
For the same information space,heterogeneous information systems adopt different information domain division standards and information description methods,as a result,the description information of the same entity is different in semantic expression and logical structure,which hinders the effective sharing of information among between systems.Therefore,a structured description model of heterogeneous information based on concept-logic tree is proposed,in which a tree structure is adopted to organize the concept sets of different systems in a general way,and it describes the logical hierarchy and semantic relations between concepts explicitly,and realizes the consistent representation of entity description information.In addition,XML-like language and relational matrix are used to centrally organize and store the representation information,so as to build up a heterogeneous information sharing framework based on a unified information space.Theoretical analysis indicates that this model can effectively describe the hierarchical structure of heterogeneous information according to semantics and logic,and this is conducive to the effective fusion and sharing of heterogeneous information based on content and semantic.
