摘要
为了解决资源库系统内容重用难及管理效率低的问题,采用分层语义网络结构提出了一种提高资源关联性及利用率的资源库系统模型。网络模型的基本节点为基于二进制大对象(BLOB)的设计资源元,以适应分布式资源抽取及数据库存储的要求。给出四类语义关系的形式化表述以构造分层语义网络,建立了资源组织、管理的逻辑模式。提出了覆盖资源特征及功能描述等的资源元相似度计算方法,实现了联想导航及评价筛选算法。该模型开发的系统已在实际企业中应用并集成,增强了设计资源数据间的关联性,提高了利用率。
In order to solve problems of reuse difficulty and low management efficiency of resource base system, a resource-base system model was proposed based on hierarchy semantics network. First, a meta-design resource (MDR) structure was built based on Binary Large Object (BLOB), therefore MDR could act as basic component to extract and store resource in distributed database and also act as the basic node in Hierarchy Semantics Networks. Then, four kinds of semantics relationship were provided to build hierarchy semantics networks so as to organize, manage the design resource. After getting a quantity of resources in the Hierarchy Semantics Networks, a similar-degree algorithm between two MDR cases was presented, which had covered resources characteristics and functions descriptions. The process of association-based searching, resource evaluating and filtering were carried out based on the algorithm method. A resource system was developed based on the model. The application in a design enterprise indicated that the system has improved connections among resources and systems' utilization rate.
