A network problem diagnosis expert system based on web services

Web services are a link of service-oriented architecture (SOA), a hot research topic in recent years. Their application is present in collaborative commerce and other service-oriented systems. This study incorporates two major theoretic frameworks, expert systems and Web services, and applies them to computer network problem diagnosis in order to help users find appropriate recommendations and solutions for different network problems facing them. The system in the study employs the ASP.net environment for development in order to demonstrate the control and knowledge segregation characteristics. SQL server is selected as the knowledge base storage tool to give managers more system flexibility and allow them to easily modify contents of the knowledge and rules. Further, due to the cross-interface characteristics of Web services and the fact that the simple object access protocol (SOAP) employs the hyper text transfer protocol (HTTP) as the basic transmission protocol, there will be more and more platforms supporting Internet browsing in the future as mobile computation technology and equipment mature. The system therefore will be in line with the trend. It will be applied to different software/hardware platforms to maximize application benefits.

Integration of Heterogeneous Medical Decision Support Systems Based on Web Services

This study employs the framework of web services in conjunction with Bayesian theorem and decision trees to construct a web-services-based decision support system for medical diagnosis and treatment. The purpose is to help users (physicians) with issues pertinent to medical diagnosis and treatment decisions. Users through the system key in available prior probability and through computation based on Bayesian theorem obtain the diagnosis. The process helps users enhance the quality and efficiency of medical decisions, and the diagnosis can be transmitted to a decision-tree-based treatment decision support service component via XML to generate recommendation and analysis for treatment decisions. On the other hand, features of web services enable this medical decision support system to offer more service platforms than conventional one. Users will have access to the system whether they use Windows, Macintosh, Linux or any other platforms that connect with the Internet via HTTP. More important is the fact that after the system is completed all Internet service providers will be able to access the system as a software unit freely and quickly. This way, the goal of this study to provide medical decision support tools and speedily integrate heterogeneous medical decision support systems can be effectively attained.

Using SOA concept to construct an e-learning system for college information management courses

Current e-learning websites are built with different programming languages, data storage formats and system architectures, making it hard for data to be interoperable. Therefore, e-learning systems must have a standardized platform to allow teaching resources and system functions to be shared and reused. This issue can be effectively resolved using SOA (service-oriented architecture) concept and web service technology that has open standards and XML (extensible markup language), which allow e-learning systems developed using different programming languages to share resources, and significantly reduces the cost system developers need to spend in constructing and maintaining the system. This study uses web service components developed with Microsoft .NET and XML to construct a teaching platform with standard specifications under SOA, allowing system developers to rapidly construct an e-learning system based on web services.

Applying Case-Based Reasoning and Expert Systems to Coastal Patrol Crime Investigation in Taiwan

Enhanced decision-making quality of crime investigation can ensure effective implementation of a nations law-enforcement tasks across the board and contribute positively to its overall security and development. This study proposes the idea of applying case-based reasoning (CBR) and experts systems (ES) in conjunction with computer-assisted instruction (CAI) to crime investigation. It delves into illegal smuggling of immigrants in coastal patrol for case studies. Ocean territory law enforcement is the cornerstone of national security. Effective ocean territory law enforcement helps enhance overall national security and development. This study takes issues regarding illegal smuggling of immigrants found in coastal patrol as subject of case studies. It classifies and analyzes patterns of illegal smuggling for the purpose of establishing a crime investigation system (CIS) against illegal smuggling.

A SOA-based Expert System for Wireless Networks Problem Diagnosis

Service-oriented architecture (SOA) is a system architecture model consisting of standardized components such as web services. Its purpose is to provide corporations a flexible integrated interface that can be used repeatedly. Past application systems, including expert systems, were unable to meet the requirement of reusability. Web services wipe out the barriers in system development and help system developers effectively meet user requirements. This study incorporates SOA and web services with expert systems built for wireless LAN (WLAN) problems to turn the WLAN problem diagnosis expert systems into a service component structured on web services. In this manner, external systems can transmit diagnosis requests via HTTP to the WLAN problem diagnosis expert system and obtain results from it. The WLAN problem diagnosis function of this system can help users deal with connection failures between their wireless devices and the access point, or denial to provide service caused by software setup. It helps users who transfer from wired networks to WLAN effectively identify the source of the problem and avoid unnecessary time spent on searching for answers to the problems.

Applying Web Service Technology to Build a Wireless LAN Problem Diagnosis Expert System

This study converts the professional knowledge in WLAN problem diagnosis to the rules in the knowledge base and turns the inference engine, explanation subsystem and knowledge base of the entire expert system into service components through web services. In this manner, external systems can transmit diagnosis requests via HTTP to the WLAN problem diagnosis expert system and obtain results from it.

An e-learning System for Information Management Education Based on Web Services

Cost reduction is a major issue in the construction of e-learning systems. Software components of web services are characterized by being reusable and interchangeable, and are therefore able to reduce waste of educational resources, as well as lower system development cost. This study uses web service components developed with Microsoft. NET and XML technologies to construct a teaching platform with standard specifications, allowing system developers to rapidly construct an e-learning system based on web services.

Using Expert Systems and Cloud Computing to Build a Diabetes Diagnosis System

This study combines an expert system with cloud computing, establishing the expert system on a cloud platform to provide users with assistance and recommendations about diabetes and diabetic retinopathy diagnosis. This study mainly adopts an empirical approach. The first step is to define the research topic, and then propose questions and the research purpose based on the research background and motivation. Research results are related to three areas, specifically diabetes and diabetic retinopathy, expert systems, and cloud computing. After analyzing and organizing the literature, the research method and scope of research are established with a system design based on the three areas. This study then develops a prototype system to validate, evaluate, and test the expert system. Finally, study gives the conclusion and recommendations.

A Knowledge Management System Integrating Collaborative Commerce for Product Development in Supply Chain

Considering the rapid progress of information technology (IT) and volatility of the marketing environment, the past concept that enterprises run the whole show, has become insufficient in an environment so volatile, challenging and competitive, demonstrating the need of up and downstream supply chain cooperation to survive. Therefore, this research aims at the benefits and related functions of collaborative commerce concepts and knowledge management, constructing a system with the integration and application of collaborative commerce and knowledge management, and then explains the operation of this system through a system prototype, in hopes of proving the practicability of knowledge management and collaborative commerce integration, which will help enterprises gain better competitiveness.
