  • It has been widely accepted that expert systems must reason from multiple sources of information that is to some degree evidential - uncertain, imprecise, and occasionally inaccurate - called evidential information. Evidence theory (Dempster/Shafet theory) provides one of the most general framework for representing evidential information compared to its alternatives such as Bayesian theory or fuzzy set theory. Many expert system applications require evidence to be specified in the continuous domain - such as time, distance, or sensor measurements. However, the existing evidence theory does not provide an effective approach for dealing with evidence about continuous variables. As an extension to Strat's pioneeiring work, this paper provides a new combination rule, a new method for mass function transffrmation, and a new method for rendering joint mass fuctions which are of great utility in evidence theory in the continuous domain.

  • In this paper, we design and implement a real-time route guidance system(RGS) in large-scale networks. Coupled with the well-known mathematical routing algorithms, we devise an RGS for knowledge aquisition and self-learning ability within the framework of the expert system. Through off-line construction of database, on-line treatment of unexpected traffic accidents, etc., the developed RGS can provide drivers with good quality real-time routing information. The practical effectiveness of the proposed system is demonstrated in terms of response time and route appropriateness.

  • For joint value creation, collaboration among different interested parties is vital and should be supported by information technology. Currently, both government and private companies have launched websites to collect ideas. However, the information poor, including the visually disabled, have difficulty in gaining access to those websites. Therefore, the aim of this paper is to evaluate the level of web accessibility to websites, operated by companies or the government, for idea proposals. According to the automatic assessments, regarding proposal specific websites, 77%, 69% of the websites operated by the government and 41%, 44% of those operated by private companies were extremely inadequate. According to the expert's assessments, regarding proposal specific websites, 67%, 52% of the websites operated by the government and 39%, 26% of those operated by private companies were extremely inadequate in their level of accessibility. A range of policies should be prepared to improve web accessibility.

  • Over the past decade, changes in product development processes and increased consumer demands have dramatically influenced engineering working practices and targets. The information technology revolution has made its appearance concurrent to this relentless escalation in product engineering requirement. It has offered hopes for improved productivity despite these increasing demands. The wide availability of personal computing power, virtually inexhaustible sources of information and an abundance of computerized engineering tools have created great expectations. CAPP (Computer Aided Process Planning) Expert system and database were developed using VB.NET and Microsoft SQL 2000 Server.

  • While use of computers to teach English in a conventional educational environment promotes motivation and effective learning in students, the method generates problems such as provision of learning materials without consideration of teaching methods and evaluation without consideration of individual differences in students. To solve these problems and produce a superior system, we propose knowledge representation of expert module for an Intelligent Tutoring System (ITS).

  • The statistical survey and analysis is much restricted to time, space and material. The statistical survey and analysis could hardly resume. The statistical survey and analysis is very important to create various and accurate information. The statistical survey and analysis which is not a expert knowledge have many problems in productivity of information, reliability and etc. In this paper, we study the design and Implementation of web-based statistical survey and analysis consulting system which a client meet easily a statistical expert on the web.

  • This paper presents a rule extraction algorithm RE to acquire explicit rules from trained neural networks. The validity of extracted rules has been confirmed using 6 different data sets. Based on experimental results, we conclude that extracted rules from RE predict more accurately and robustly than neural networks themselves and rules obtained from an inductive learning algorithm do. Rule extraction algorithm for neural networks are important for incorporating knowledge obtained from trained networks into knowledge based systems. In lieu of this, the proposed RE algorithm contributes to the trend toward developing hybrid and versatile knowledge-based system including expert systems and knowledge-based decision su, pp.rt systems.

  • This research proposed the necessary capability of cyber security professional personnel for cyber security education and training. Cyber security professional personnel were required specialized capability because the curriculum of cyber security education and training is structured around practice and training. Based on the knowledge, skills, and attitudes of professors, we derive candidate capabilities and index through the results of precedent research. As a result, we derived capability such the candidate capability group as teaching qualification, expert knowledge, practical ability, lecture ability, and research ability, and detailed capability index was derived accordingly. Finally, based on the questionnaire results of the professors related to the information security, it was determined that the capability required for the cyber security education and training professional personnel were expert knowledge, practical ability, and lecture ability. Among the capabilities, executive ability means that they have to fulfil abundant executive experience due to the high proportion of practical training due to the characteristics of cyber security education and training.
