基于移动Agent的元数据自动抽取研究

The Research of Automatic Metadata Extraction Based on Mobile Agent

语义Web是在分布式环境下构建复杂系统的一种新兴技术。在分析语义Web与移动Agent的基础上,提出了基于移动Agent的元数据自动抽取系统模型。该系统由三个层次构成网络信息层、移动Agent平台和元数据提取及管理模块,语义Web为解决元数据信息处理提供了一个基本的技术框架,其中核心层为XML,RDF,Ontology。最后,给出了改进的粒群优化算法作为移动Agent路由判定算法,为下一步研究开发比较成熟的软件产品奠定了良好的基础。

Semantic web is a kind of new technology for constructing complex system under the distributed conditions. The model of automatic metadata extraction based on mobile Agent is introduced in this paper. The system is composed of the network information layer, mobile Agent platform and the extraction and management metadata module. The semantic web provides a foundational technology framework for dealing with metadata information. XML, RDF, Ontology constitute in the kernel layer. At last, the improved particle swarm optimization algorithm regarded as the route determined algorithm based on mobile Agent is presented. The algorithm will establish good foundation for researching more mature software product.
