At the beginning of this paper , a plan of ontology building method is forwarded , which includes four steps : information extraction from relational database , concepts in ontology generation , pointing out the relationship of the concepts , integration with existing ontology 本文首先提出基于关系数据库本体构建方案,其包括关系数据库资源提取、本体概念生成、概念之间关系标注和与已有本体进行集成四个过程。
On the base of analyzing the structure , building methods and running characters of the intrusion detection system , and according to the practical requirements , this paper puts forward an intrusion detection expert system based on cve ( common vulnerabilities and exposures ) 本论文在全面分析国内外入侵检测系统的系统结构、构建方法、运行特点等基础上,结合实际需要提出开发一个基于cve的实时入侵检测专家系统。
On the base of analyzing the structure , building methods and running characters of the intrusion detection system , and according to the practical requirements , this paper puts forward an intrusion detection system based on cve ( common vulnerabilities and exponsures ) . the main research objects are the exposures in cve 本论文在全面分析国内外入侵检测系统的系统结构、构件方法、运行特点等基础上,结合实际需要提出开发一个基于cve的实时入侵检测专家系统。课题以国际公开的cve列表所列漏洞为主要研究对象,深入探讨了cve漏洞特征、体系结构等,在此基础上构建具有cve特征的入侵检测知识库。
According to analyzing for the actuality of smme and the influence of information technology over the methods of product development , in this paper , an architecture of icpd system and the building methods of inter - enterprise cooperative alliance are put forward , the integrating methods of network platform , the modeling methods of product information model , principles for development process modeling , principles for task distributing and scheduling , and the modeling methods of organization and the cooperative mechanism of team work are researched 本文在分析中小型制造企业现状以及信息技术对产品开发方法影响的基础上,提出了信息化协同产品开发系统的体系结构和企业间协作联盟的建立方法,研究了系统环境的集成方法、产品信息建模方法、开发过程建模原理、任务分解调度原理、组织建模方法与协作机制等,并在此基础上开发了水泵协同设计过程管理系统。
The dynamic model of grey is comeing or bring into being the function concept with the grey serving as the foundation , and with the differential drawing up closing the pattern the building method for the nucleus , to build pattern thought is directly changing the time alignment to the differential equation grey system , thus builds that the development abstracting the system changes the dynamic model , and namely grey ' s dynamic ' s model , ' s brief note is for gm 灰色系统理论与方法的核心是灰色动态模型,其特点是生成函数和灰色微分方程。灰色动态模型是以灰色生成函数概念为基础,以微分拟合为核心的建模方法,灰色系统建模思想是直接将时间序列转化为微分方程,从而建立抽象系统的发展变化动态模型,即greydynamicmodel ,简记为gm 。
