  • At present, Web services become main means to construct web applications. As the number of web services grows and various kind of web services have been produced, QoS properties of web services are one of important criteria to select more appropriate web services. However, the selected web services may become inappropriate for the Requester's requirements, because QoS is kind of dynamic properties. this paper proposes a framework that proposed that finds an appropriate web service for Requester's QoS requirements, and dynamically replaces an inappropriate web service with right one. The problems which happen in substitution step are also identified and the solutions are described with an illustrative example.

  • Web data mining aims at discovering useful knowledge from various Web resources. There is a growing trend among companies, organizations, and individuals alike of gathering information through Web data mining to utilize that information in their best interest. In science, cloud computing is a synonym for distributed computing over a network; cloud computing relies on the sharing of resources to achieve coherence and economies of scale, similar to a utility over a network, and means the ability to run a program or application on many connected computers at the same time. In this paper, we propose a new system framework based on the Hadoop platform to realize the collection of useful information of Web resources. The system framework is based on the Map/Reduce programming model of cloud computing. We propose a new data mining algorithm to be used in this system framework. Finally, we prove the feasibility of this approach by simulation experiment.

  • 일반적으로 사용자가 인터넷 서비스를 제공받기 위해서는 자신의 정보를 먼저 등록해야 한다. 그러나 인터넷 서비스의 활용이 많아질수록 이와 같이 선 등록되어야 하는 정보의 양도 많아지며 또한 이들 정보가 불일치하는 문제가 발생한다. 본 논문은 이와 같은 문제를 해결하기 위해 사용자 Identity 정보를 웹 상에서 공유하는 기술인 Liberty Alliance 의 ID-WSF(Identity Web Service Framework)에 대하여 기술한다.

  • WebDAV는 IETF 표준으로서 웹상에서 분산 저작을 지원하도록 HTTP를 확장한 프로토콜이다. WebDAV 클라이언트는 WebDAV 프로토콜을 이용하여 WebDAV 서버자원을 관리하는 도구이다. 현재 WebDAV 기반의 자원 관리가 널리 사용되면서 무선 네트워크 환경에서 동작하는 클라이언트의 필요성이 증대되고 있다. 본 논문에서는 무선 네트워크를 지원하는 PDA에서 동작하는 WebDAV 클라이언트의 구현에 대하여 기술한다. 개발된 클라이언트는 간결한 사용자 인터페이스를 제공하며 WebDAV의 기본 메소드를 지원한다. 사용자는 인터페이스와 기본 메소드를 이용하여 WebDAV 서버에 자원을 등록하고, 서버 자원에 대한 열람, 검색, 이동 및 삭제를 할 수 있으며, 서버 자원을 내려 받을 수 있다. 본 클라이언트는 PDA에서 동작하기 위해서 .NET Compact Framework를 기반으로 구현 하였으며 관련 에뮬레이터를 이용하여 실험하였고 이를 실제 PDA장치인 'HP iPAQ hx2700'에 이식하여 검증하였다.

  • As a fundamental knowledge source in a global learning environment, it is feasible to apply the relational database management systems (RDBMS), object-oriented database management systems (OODBMS), and other traditional DBMS. However, the traditional DBMSs are not feasible in semantic knowledge/ontology representation and inference. One of the reasonable ways to overcome the limitations is the semantic web-based business support framework. Especially, in this study, we focused on the development of semantic web ontology and natural language (NL)-based inference framework. To validate the efficiency of the proposed framework, we considered a reasonable scenario for course recommendation in a university.

  • Importance of coordination among heterogeneous devices is significantly increasing to meet the challenges presented by the evolvement of the ubiquitous computing environment. The web services technology is going up as a promising solution to support the inter-operability between such heterogeneous devices via well-defined protocol. Currently, ECA(Event-Condition-Action) rule based framework for coordinating devices is proposed, it is called as WS-ECA(Web Services-ECA) framework. This framework was basically based on the web services and proposed the ECA based rule language, And this also proposed the framework that could enable the device coordination based on proposed rule language. In this paper, we propose the protocol among the components of WS-ECA framework to support dynamic feature for ubiquitous environment, and we also propose WSDL extension to support service and event descriptions these are provided in components of this framework.

  • WebDAV 프로토콜은 웹상의 공동 저작활동을 지원하기 위한 IETF 표준으로써, 원거리에 있는 사용자들 간에 파일을 공동 편집하고 관리할 수 있도록 해주는 HTTP 프로토콜의 확장이다. 이것은 웹상에서 가상의 작업공간을 구성함으로써, 원격 사용자들 간에 새로운 방식으로 공동작업을 가능하게 한다. 무선 네트워크 기술과 무선 장치의 발달로 이동을 하면서 WebDAV 서버에 접속한 후 협업을 수행한다면 유선 환경보다 효율적인 협업을 할 수 있을 것이다. 본 논문에서는 .NET Compact Framework 환경에서 동작하는 PDA WebDAV 클라이언트를 설계하였다. 본 클라이언트는 무선 네트워크를 지원하는 환경에서 PDA를 이용하여 WebDAV 서버와 HTTP 요청을 통하여 서버 자원을 확인할 수 있다. 이러한 PDA WebDAV 클라이언트는 PDA 환경에 맞는 인터페이스를 가져야 하고, 또한 WebDAV 명세를 따라야 한다. PDA WebDAV 클라이언트는 공간의 제약을 받지 않는 PDA를 이용함으로써 자료의 효율적인 공유 및 교환을 통하여 능동적인 협업 환경을 구축 할 수 있다.

  • This study proposes a Natural Language Query Framework (NLQF) on the semantic web to support the intelligent deduction at semantic level. A large number of former researches are focused on the knowledge representation on the semantic web. However, to revitalize the intelligent agent (IA)-based automated e-business contract with human customers, there is a need for semantic level approach to the web information. To enable accessing web information at semantic level, this paper discusses the pattern of complex natural language processing at first, and then the semantic web-based natural language inference in e-business environment. The NL-based approach could help the IAs on the web to communicate with customers and other IAs with more natural interface than traditional HTML-based web information. Therefore, our proposed NLQF will be used in semantic web-based intelligent e-business contracts between customers and IAs.

  • 인터넷을 이용하는 사용자들은 원하는 정보를 획득하고 타인들과 소통하기 위한 방법으로 소셜 네트워크 서비스를 이용한다. SNS는 사용자별로 차별화된 기능을 제공함으로써 수요자를 증가시키지만 이를 활용하는 사용자들은 무분별한 콘텐츠를 접함으로써 사용자 인터페이스에 대한 불편함은 더해가고 있다. 본 연구는 SNS를 이용하는 사용자들의 사용자 편이성을 증가하고 콘텐츠 접근성을 강화하는 방안으로 원하는 관심사만 자동으로 수집하여 열람하도록 JAVA WEB CRAWLING을 활용하여 시스템을 개발하였다.

  • Web services are independent on a platform and are suitable in the Ubiquitous environment which an interaction for each device. Ubiquitous web services can use various applied service in any network neighborhood or terminal. Main characteristic of Ubiquitous is context-awareness. Therefore, Ubiquitous web services must include context-aware control process and protect user privacy because context-aware environment collects privacy data. But current web services standard is not specially designed in respect of context-communication. Therefore, the framework which can add flexibility in transmission of context is required. Our Framework can give extension for context and can communicate flexibly Context information for every session. Therefore, Our Framework can solve overhead problem of context in SOAP message and protect user's privacy according to user preference.
