Abstract

In this paper, multi-agent system using negotiation and persuasion method with reinforcement learning, implemented on broker's board agent system is proposed. The objective of this research was to design prototype of broker's board multi agent system with negotiation and persuasion capability based on reinforcement learning. For evaluation the agents, we did learning process, in order to find the agent, who makes the best solutions for raising capital.

Abstract

The illegal distribution of duplicated contents on the Web is causing digital content providers great economic loss. Therefore, Information security is becoming a more important factor in distribution of digital contents. In this study, we designed a digital contents distribution system based on the public key techniques in hierarchical web caching structures. The superior performance of the proposed system has been proven in the experimental tests. The results of experiment show that the supposed system improved the security of DC without decreasing process speed and improved user convenience.

Abstract

Because of development of information technology and acceleration of enterprise e-business, the importance of electronic commerce system has been growing rapidly. Electronic commerce system must provide convenient interface, easy and fast searching function, and product information satisfied customer's requirement. For that many studies about the electronic commerce system that used a reasoning technique and an agent technology conducted largely. In this paper, we design a sales agent with hybrid reasoning method which is composed of case-based reasoning and rule-based reasoning for high customer satisfaction. Also, we were shown on an appropriateness of a proposal system by an experiment. Keywords: Hybrid Reasoning, Intelligent Agent, Case base reasoning, Rule base reasoning. [ABSTRACT FROM AUTHOR]

Abstract

The key features of mobile agent systems are mobility, autonomy, and intelligence. On integrity protection within mobile agent technology, mobile agent integrity should be protected against attacks from malicious hosts and other agents. In this paper, we design flexible Mobile Agents (FMA). The traditional mobile agents consist of fixed code parts. But FMA consist of flexibly upgradeable agent code part for that new agent code modules can be added and redundant code modules can be deleted on the executing requirement. FMA prove to be more flexible in agent-based web systems compared to the traditional static-type mobile agent. Keywords: Mobile Agent, Intelligent Agent, Security, Flexibility.

46. A Performance Improvement of Web Service System Based on the Probability Distribution Characteristics.

Author

Chung, Yeh-Ching, Moreira, José E., Ko, Il Seok, and Na, Yun Ji

Abstract

A web caching technology, which analyzes and reflects the reference characteristics of users, is required to effectively operate an electronic commerce system, because the reference characteristics of web objects becomes a major factor in decreasing the performance of an electronic commerce system. Therefore, it is necessary to study the increase in the performance of web caching based on the probability distribution of the object reference characteristics in order to increase the performance of an electronic commerce system. This paper proposes a web caching method based on the probability distribution of the object reference. Keywords: web object & web caching, probability distribution characteristics.

48. The Modified DTW Method for On-Line Automatic Signature Verification.

Author

Hai Jin, Reed, Daniel, Wenbin Jiang, Cho, Dong Uk, Bae, Young Lae J., and Ko, Il Seok

Abstract

Dynamic Programming Matching (DPM) is a mathematical optimization technique for sequentially structured problems, which has, over the years, played a major role in providing primary algorithms in pattern recognition fields. Most practical applications of this method in signature verification have been based on the practical implementational version proposed by Sakoe and Chiba [1], and is usually applied as a case of slope constraintp = 0. We found, in this case, a modified version of DPM by applying a forward seeking implementation is more efficient, offering significantly reduced processing complexity as well as slightly improved verification performance.
