This study describes the concept of link resolvers using OpenURL. Then, the study analyzed the commercially available link resolvers in terms of remote & local hosting, title list, customization of the services and usage statistics. The results will help the libraries select the appropriate link resolvers that are relevant to the features of the libraries.

The purpose of this study is to propose a plan to implement the comprehensive linking system centered on identifiers in order to provide seamless academic information services to researchers. To achieve this goal, interviews were conducted with 17 researchers from five centers and one secretariat belonging to KISTI. The contents of the interview are about the establishment and management status of the identifier of the academic information service DB. As a result of the interview, it was found that the identification rate for identifiers such as KOI was high in the case of domestic articles DB, but the identification rate for global identifiers such as ORCID was low in the case of foreign articles DB except for DOI. To solve this problem, this study proposes the council for joint use of a comprehensive linking system to build the comprehensive linking system model centered on identifiers. The joint use council will be organized around domestic academic information distribution institutions, and the council is expected to discover and implement new services through ID linkage by collecting foreign identifiers.

최근에는 도서관 웹사이트보다는 상용 검색엔진이나 포털사이트를 통해 학술정보 검색서비스를 이용하는 이용자가 많아지고 있다. 링크리졸버는 검색엔진과 도서관 서비스를 연결할 수 있으며, 이용자는 한 번의 클릭으로 소속 도서관에서 구독하고 있는 자료에 접근할 수 있다. 본 연구에서는 국가과학기술정보센터(NDSL)에서 서비스하고 있는 과학기술정보와 외부의 학술자원을 링킹할 수 있는 링크리졸버를 OpenAPI 형태로 설계하고 구현하였다.

Web based entity linking cannot be applied in tweet entity linking because twitter documents are shorter in comparison to web documents. Therefore, tweet entity linking uses the information of users or groups. However, data sparseness problem is occurred due to the users with the inadequate number of twitter experience data; in addition, a negative impact on the accuracy of the linking result for users is possible when using the information of unrelated groups. To solve the data sparseness problem, we consider three features including the meanings from single tweets, the users' own tweet set and the sets of other users' tweets. Furthermore, we improve the performance and the accuracy of the tweet entity linking by assigning a weight to the information of users with a high similarity. Through a comparative experiment using actual twitter data, we verify that the proposed tweet entity linking has higher performance and accuracy than existing methods, and has a correlation with solving the data sparseness problem and improved linking accuracy for use of information of high similarity users.

CrossRef operates a cross-publisher citation linking system based on the DOI(R) global identifier. The number of organization building a reference citations linking structure through CrossRef is increasing. This paper concentrates on developing a Citation Matcher Solution to effectively build the reference linking structure. Citation Matcher automatically builds and processes the reference citation and identifier mapping which used to be handled manually. After the copy & paste of the reference citation, analyzation is processed to parse the journal title, author name, volume, issue, and start pages from the free style text. CrossRef, PubMed, and YesKISTI's identifiers are collected by through a standardized method. Renovation of the building process for domestic scholastic resources' reference linking and matching will be made possible by using a Citation Matcher. The connection between resources and seamless access for the electronic full-text will enhance the usability.

Science-based Industry which is future growth industry leading national competitiveness in knowledge-based society is highly science-dependent field when developing technologies. And highly science-based field is absolutely dependent on core scholarly papers. Due to researchers' need of academic papers related to developing technologies and advances of linking technologies, it is possible to link service between patents and scholarly papers. This paper's purpose is to describe on implementation linking service between EPO patent and papers that cited on search reports. First, it describe case study of other linking services. Second, it describes a kinds of data used in linking services. Lastly, it describe implementation of linking different kinds of contents (patents and papers) in KISTI.

기존의 통합 시스템은 이미 구축된 자윈을 재활용하여 데이타의 구축비용을 줄이고자 하는 의도에서 연구되었다. 특히 GIS에서는 공간 데이타의 규모가 방대하므로 그 구축비용이 더욱 증가한다. 이로 인해 공간 데이타를 위한 통합 시스템의 필요성이 대두되다. 최근 웹의 사용자 수와 그 응용의 수가 증가함에 따라 웹에서의 공간 데이타를 이용한 응용의 필요성이 승가하고 있다. 이에 따라 웹 환경에서 분산된 공간 데이타의 통합 시스템이 요구된다. 기존의 미디에이터(Mediator)를 사용한 통합에 비하여 웹을 기반한 공간 데이타의 통합은 웹의 환경적 특성과 공간 데이타의 크기와 형태 등을 고려해야 한다. 본 논문에서는 OGC(OpenGIS Consortium)의 웹 매핑 기술인 WMT(Web Mapping Testbed)의 중첩 맵 서버 (Cascading Map Server)를 사용하여 공간 데이타를 통합한다. 통합 과정에서 요구되는 표준화된 데이타 모델과 인터페이스는 OGC가 최근 제안한 GML(Geography Markup Language)과 웹 맵 서버 인터페이스를 이용한다. 본 논문은 XML의 XLink와 XPointer의 개념을 가진 융합 서비스(Fusion Service)기법을 중첩 맵 서버에 도입한 융합 맵 서버(Fusion Map Server)를 제안한다. 이러한 통합 방식은 데이터 사이의 관계성을 고려한 링킹 기반 통합이므로 통합 응용의 복잡성을 줄일 수 있을 뿐만 아니라 물리적 변환 등에서 생성되는 연산 비용을 줄일 수 있는 장점이 있다.

When spatial data which a user requests are stored various data servers in web mapping environment, it is necessary to access one more map servers to gain data and then integrate them. This paper designs and implements a fusion map server for web mapping. The proposed fusion map server has three characteristics. First, it has customizing metadata which reflect various user's requests. Second, it provides fusion services which integrate spatial and non-spatial data. Last, it uses the dynamic liking method to support the fusion services efficiently. We design and implement a publisher client, a map server and a fusion map server for proposed map server.

The exponential increase of digital contents brought about the e-Challenge crisis to the librarians. How can all the e-resources be managed effectively? How can we detect all the broken links? How can we assist the users to the right resources? This paper concentrates on building CLICK(Cooperative Link Center in KOREA) as a knowledge compass by collecting diverse science & technology information and creating tight coupled links between information resources for reference linking and providing users with the optimal route for the resource per user. If the publishers, Abstract & Index DB, Searching Portal, Electronic Libraries, Full-text DB and Aggregator can be linked by using a standardized way through a CLICK, the service channels can be diversified. Users can select the channels without rein under according to a use purpose and conditions.

With the era of the 4th Industrial Revolution, the number of data-centric integrated researches increases. The integrated researches make information identification and linkage more important, so it is necessary to seek a method to efficiently manage and share academic-information for supporting the researches. Therefore, this study aims to analyze identification system and linkable information types of 12 major academic search engines and bibliographic databases(ASEBDs) in Korea and abroad and to propose a method to identify and link academic-information. The analysis was conducted 2 times, and academic-information types, searchable fields, linkable information types, used identification system were investigated. As a result, the ASEBDs link directly or/and indirectly 3~4 information types based on their own identifiers with persistent identifiers. In addition, they identify academic-information semi-automatically based on machine learning methodology and collect and manage the related data. Finally, the method for academic-information linkage was proposed in terms of practice and society: linkage based on persistent identifiers and linkage based on collaborative network of institutions.
