文摘Automatic Question Answer System(QAS)is a kind of high-powered software system based on Internet.Its key technology is the interrelated technology based on natural language understanding,including the construction of knowledge base and corpus,the Word Segmentation and POS Tagging of text,the Grammatical Analysis and Semantic Analysis of sentences etc.This thesis dissertated mainly the denotation of knowledge-information based on semantic network in QAS,the stochastic syntax-parse model named LSF of knowledge-information in QAS,the structure and constitution of QAS.And the LSF model's parameters were exercised,which proved that they were feasible.At the same time,through "the limited-domain QAS" which was exploited for banks by us,these technologies were proved effective and propagable.
文摘H3C CAS云计算管理平台为H3C公司推出的统一虚拟化管理平台,目前很多企业采用此虚拟化平台来实现虚拟机的创建与管理,进而提高企业计算资源的管理效率。为了在H3C CAS平台上实现云主机高可用的特性,采用基于因特网的小型计算机系统接口(Internet Small Computer System Interface,iSCSI)存储架构进行共享存储,将创建虚拟机的镜像文件和虚拟机磁盘文件保存在共享存储磁盘上,以应对某些突发情况导致虚拟机所在主机宕机造成虚拟机响应中断的情形。通过VMware Workstation软件搭建云计算管理平台(Cloud Automation System,CAS),并使用iSCSI作为共享存储架构进行仿真实验。实验结果表明,iSCSI共享存储方式可以延长虚拟机的平均故障间隔时间,提升用户体验。
