For the construction of accurate scientific citation information, author disambiguation should be primarily resolved. This study proposes a method that utilizes URI(Uniform Resource Identifier) to create precise author citation networks. The adoption of URIs for representing authors and papers in this study enables us to maintain the integrity of constantly changing citation information and to guarantee the accessibility to the right literature. In experiments, we extracted 2,872 author-centric citation relation pairs from recent major IT-related proceedings written in Korean. From those, 135 citation network groups were discovered. The findings of this study are expected to be applied to a variety of researcher network services and scientific information portal services.

The development of Semantic Web basically requires knowledge induced from the formalization and semantization of information, and thus ontology should be introduced as a knowledgization tool. URI(Universal Resource Identifier) is an indispensible scheme to uniquely indicate individuals on ontology. However, it is difficult to find the use cases of URI in real data including science & technology publications. This paper describes the method to construct human resources based on URI which are the critical components on national R&D reference information ontology. We use co-authors, e-mails, publication date, and affiliation for discriminating authors with the same strings. HRST is referred to acquire human resource URIs. We expect the human resources would be adopted to outcome analysis applications such as researcher network analysis and outcome statistics.

과학기술 문헌에 대한, 정확한 인용 정의의 제공을 위해서는 인용 관계를 구성하는 인력에 대한 동명이인 문제가 우선적으로 해소되어야 한다. 본 논문에서는 정확한 저자 중심의 인용 관계 및 네트워크를 구축하기 위해 URI(Universal Resource Identifier)를 이용하는 방법을 제안한다. 본 연구의 특징은, 지속적으로 추가되고 갱신되는 인용 정보를 일관성 있게 유지하고 정확한 문헌으로의 접근성을 보장하기 위해, 시맨틱웹 기술의 하나인 URI를 문헌과 저자에 적용하여 저자 중심 인용 관계 및 네트워크를 구축한다는 것이다. 실험에서는, 국내 학술대회 발표 논문들로부터 2,872개의 저자 중심 인용 관계 쌍을 추출하였고, 이를 바탕으로 구축한 저자 인용 네트워크에서는 135개의 인용 네트워크 그룹을 발견할 수 있었다. 본 연구의 결과는 향후 국가과학기술인력 종합정보시스템에서 제공하는 인력 DB 및 과학기술정보 포털서비스인 YesKiSTi와의 연계를 통하여 새로운 개념의 다양한 연구자 네트워크 서비스를 제공할 수 있을 것으로 기대된다.

다양해진 디지털 미디어와 디지틀 컨텐츠의 유통이 점차 대용량화에 따른 변화와 콘텐츠 서비스 환경 구축의 개발이 본격화되고있다. 또한 다룰 수 있는 사용자 단말기의 다양화로 인해, 자원을 식별하고 검색하기 위한 식별기호의 중요성이 인식되어져 왔다. 이러한 물리적 콘텐츠와 디지털 콘텐츠의 통합 서비스의 방안으로 정보자원에 대한 효율적인 접근과 저작권 보호를 위한 필요성에 의해 2차원 바코드 기술을 이용한 MPEG21 DII의 디지털컨텐츠 식별체제의 운영 방안을 검토한다.

The IoT (Internet of Things) is considered as a core technology to realize interconnected world. At this, companies composing ICT industry and standard organizations make efforts to accelerate it. IETF CoRE(Constrained RESTful Environment) working group standardized CoAP (Constrained Application Protocol) for the constrained device. CoAP has RESTful architecture and CoAP option is provided to use forward-proxy. The forward-proxy is used to translate protocol and perform requests on behalf of the client. However, communication between Internet based client and LLN(Low-power and Lossy Network) based CoAP server architecture has limitations to deploy real IoT service. In this architecture, problems like response delay, URI assignment and DoS attack can be occurred. To solve these problems, we propose the reverse-proxy based system. We consider both of static IoT and mobility IoT environments. Finally, our proposed system is expected to provide efficient IoT service.

With the development of modern society, we are all living in a world where information is shared through mass media and environment. Just as there was an identifier for the approach of information in the past analog environment, there is a demand for the continuous development and research of an original identifier for each and every digital contents of the changing digital environment. In order to present the need for standardization of effective construction concerning digital contents, this study examines the identifiers system structure of ISBN and ISSN of the analog environment and URL, URN, URC, which are under the URI system of the digital environment. After analyzing the problems of different URL identifiers construction in each university library's OPAC system, this study presents a standard device of effective identifiers patterns.

시맨틱 웹 기반의 차세대 정보 서비스인 OntoFrame2007은 시맨틱 웹과 웹 2.0 기술을 상호 보완하여 개발한 플랫폼으로 URI기반의 개체 중심적 통합 검색을 통해 Topic, Person, Event 기반의 개체 페이지를 구성한다. 각 페이지에는 Add-on 서비스를 통해 연구자 그룹, 연구자 네트워크, 통계 정보를 제공하며, 매쉬업 기술을 이용하여 매핑 서비스, 도서 서비스를 제공한다. OntoFrame2007은 서비스 설계 과정에서 Google, Google Scholar, CiteSeer, yesKisti 사이트와 비교하여 사용자의 요구사항 및 각 서비스의 장점을 최대한 반영시켰으며, 개발 단계마다 반복적 사용성 평가를 통해 사용자 중심의 서비스를 제공하도록 개선시켰다. 본 시스템에서는 URI를 통해 개체의 모호성을 제거하여 키워드 기반의 통합 검색의 한계를 극복하였으며, 사용자 질의어를 식별하여 단위 서비스로 구성된 최적 개체 페이지를 통해 정교한 검색 서비스를 제공해준다. 개체 페이지들은 키워드 검색 결과, 연구 동향 정보 및 연구자 그룹, 전문가 네트워크 및 지역별 연구 동향 등을 제공해준다.

As an information service system based on semantic web technology, $OntoFrame^{(R)}$ takes aim at a framework for providing analysis and fusion services of academic information. It currently consists of three parts: ontologies representing knowledge schema derived from academic information, $OntoURI^{(R)}$ which makes academic information into knowledge, and $OntoReasoner^{(R)}$ which performs inference and search on the knowledge. Unlike existing search engines which provides simple search services, our system provides, based on semantic web technology, several semantic and analytic services such as year-based topic trends in academic information, related topics, topic-based researchers and institutes, researcher network, statistics and regional distribution of academic information.

Even the document resources offered from web server can be represented in the form of URL/URI, it can not necessarily be guaranteed that corresponding resources exist due to a dynamic change of sewer environment In this paper, integrated document administration system is therefore proposed and modeled using the XML-RPC technology which guarantees the reliance of resources, and handles a dynamic server resource management and request of clients. The proposed system is composed of middleware and server systems. The former system manages dynamic server resources, and the latter reports the updated information of documentations stored in server by client from the server to middleware system. As a result, effective storing management of dynamic resource in distributed server could be archived and building cost of a new web server could be reduced due to an applicability to current web sewer. In addition platform independent and efficient data management was obtained by using the XML-RPC protocol.

Recently various handheld multimedia devices are spreading, and users want to share media contents across their own multiple devices. Conventional synchronization techniques for N-screen services can continuously play contents by switching from an initial device to a new device. In this case, even if a new device plays continuously contents, the initial device stops playing them. In this paper, we propose a synchronization technique in which multiple devices can share and continuously play same contents simultaneously by gathering and passing URI and current play-time of the contents. The proposed synchronization technique is built on UPnP and DLNA, and tested by implementing a wireless home media network system.
