A good e-learning system should deliver relevant learning materials to learner at the most appropriate time and locations to facilitate learners' acquisition of knowledge and skills. In this paper, we propose domain-based recommendation and retrieval of relevant materials in e- learning. Since relevancy is often domain dependent. Materials that are highly related in one domain might be irrelevant in another domain, we group users by their domains. Based on the content, multiple sets of relevant documents, one for each chosen domain, are prepared. In a search scenario, search sites are selected by domain and search is performed on the chosen relevant sites only. To demonstrate our idea, we use Virtual Conference on Genomic and Bioinformatics as the test bed and develop a presentation video access platform. The implementation involves techniques in image and video processing, database management, programming, and multimedia learning materials presentation.

Reputation has recently received considerable attention within a number of disciplines such as distributed artificial intelligence, economics, evolutionary biology, and among others. Most papers about reputation provide an intuitive approach to reputation which appeals to common experiences without clarifying whether their use of reputation is similar or different from those used by others. DF provides a Yellow Pages service. Agents in the FIPA-compliant agent system can provide services to others, and store these services in the DF of the multiagent system. However, existing DF cannot detect the fake service which is registered by malicious agent. So,a user may search these fault services. In this paper, we analyze the DFpsilas problem and propose the solution. We describe the Reputation mechanism for searching these fake services. Reputation function assumes the presence of other agent who can provide ratings for other agents that are reflective of the performance or behavior of the corresponding agents.

This paper presents a declarative programming language SOBL for data-intensive Web applications. A SOBL program separates the application data from the composition and navigation of UI data. Static Web pages are automatically generated from UI requirements, and an executable behavior specification is derived from the behavior requirements in SOBL automatically. SOBL is employed to represent the behavior requirements that involve a series of actions in a specific order, which are expressed by the compositions of certain types of control structures and triggers. It assists non-technical people to describe the scenarios of systems without the knowledge of technical details.

The agent systems can register, deregister and search the information of agent and services. Amount of the agent systems and the information according to agent and service are existed. The differences of the information specification make not easy to the relevancy about them. Thus, we propose the agent service system (ASS) to find the relevancy among the agents information and to manage them. The ASS can provide the various services to the other multi-agent systems or general systems that may be not the agent platform.

According to continuous increasing of spam email, 92.6% of recent total email is known spam email. In this research, we will show an adaptive learning system that filter spam emails based on user's action pattern as time goes by. In this paper, we consider relationship between user's actions such as what action is took after one action and how long does it take. They analyze that each action has how much meaning, and that it has an effect on filtering spam emails. And that in turn determines weight for each email. In experimentation, we will compare results of system of this research and weighted Bayesian classifier using real email data set. Also, we will show how to handle personalization for concept drift and adaptive learning.

In the process of cooperative engineering design, various events occur from design units. In order to effectively manage design updates among collaborators, we use publish/subscribe mechanism. However existing publish/subscribe systems only have the simple subscription mechanism. In this paper we introduce a concurrent engineering environment where the publish/subscribe relationship can be established based on the product structure. Information about design changes is encoded in feed format using proposed CE-RSS.

Wireless sensor networks are attractive means to monitor environment and to utilize for military. Sensor networks are increasingly improving. Operating system and routing are especially researched in times past. On the other hand, the aspect of middleware that sits between the operating system and the application did not be sufficiently discussed. The importance in sensor networks is power saving. And middleware is located between operation system and application. Middleware in sensor networks is responsible to process data effectively to minimize spending energy of sensors. Therefore this paper proposes to effectively process data using data fusion technique.

Dataset should be free from noise for carrying out tasks of Web mining well. Generally commercial Web pages have a lot of noise which are not relevant to main contents such as navigation panel, advertisements, copyright notices or other service links. In this paper, we present a new automatic Web information extractor called dasiacatch crawlerpsila which uses style sheet to extract interesting data on a target site. Style sheets are generally used for uniform presentation of Web pages in a commercial Web site. To execute catch Crawler, a user lets catch Crawler know the interesting data area by clicking the data on a Web page. The catch Crawler automatically perceives the class of style sheet for the data and generates dataset from the whole Web site following the same style sheet class. Experimental results show that our approach for extracting noiseless Web data gives over 90% of accuracy on average.

Today, the railway is very important in modern society means of public transport. Many people use the railway each day. On the other hand, with regard to railway accidents every year due to damage caused many casualties. In this paper, we propose railroad crossing accident prevention system for monitoring the situation based on OSGi for safe railway operations, about the same railroad crossing a dangerous place. This system, communication between the train and railroad crossing. So the information from the train crossing while a train driver was monitored in real time with more information than can help prevent accidents on the crossing. Using the OSGi framework, can be used widely in many hardware.

In this paper, we present a system that takes an input document and searches semantically-related documents on the Web. Relatedness is measured based on two criteria. One is to check whether some representative words inside the input document appear in candidate documents. The other is to check whether words that describe the contextual information about the input document appear in candidate documents.
