We established economic models for economic performance analysis in order to respond to changes in a rapidly changing environment. We tried to maximize business efficiency and performance of science and technology information management distribution project. The science and technology information management distribution project is significantly different from general R&D project. In this paper, it is meaningful to develop economic models to analyze economic outcomes for science and technology information management distribution project. We anticipate that these models will contribute greatly to economic performance analysis for science and technology information management distribution project.

Archival description is considered as a creation and curation process, and the results of the descriptive records can be used for archival information service. Therefore, various archival descriptive standards provide essential guidelines for establishing a semantic and synthetic structure of the archival records. In this study, the structural aspects of the archival descriptive standards were analyzed and an experimental mapping between General International Standard Archival Description (ISAD(G)), the archival standard, and CIDOC Conceptual Reference Model (CIDOC CRM), the domain ontology of cultural heritage field was performed. The data structure of ISAD(G) is examined in advance and mapping was performed using Karma as a platform. It was thus concluded that there is a need to understand the ontology-based mapping method and the event-focused domain ontology. Moreover, developing a CIDOC CRM-compatible archival ontology and restructuring the legacy ISAD(G) are needed.

The science & technology information is core point of the knowledge based society which will accomplish the role which economic development is lead. Simultaneously, Korea will jump at powerful country of knowledge information. But, There is not analysis about affects in the economic growth and various economic structure which follows in national knowledge information system development. This research analyses the economic ripple effects, in terms of production inducement effect, added value inducement effect, import inducement effect, labor inducement effect, of national knowledge information system development in KISTI from 2001 to 2008, using an input-output analysis of the bank of Korea(2007). It also examines economic propriety using an benefit-cost analysis for national knowledge information system development.

Knowledge map is widely used to represent knowledge in many domains. This paper presents a method of integrating the national R&D data and assists of users to navigate the integrated data via using a knowledge map service. The knowledge map service is built by using a lightweight ontology modeling method. The national R&D data is integrated with the research project as its center, i.e., the other R&D data such as research papers, patent, and project reports are connected with the research project as its outputs. The lightweight ontology is used to represent the simple relationships between the integrated data such as project-outputs relationships, document-author relationships, and document-topic relationships. Knowledge map enables us to infer the further relationships such as co-author and co-topic relationships. To extract the relationships between the integrated data, a RDB-to-Triples transformer is implemented. Lastly, we show an experiment on R&D data integration using the lightweight ontology, triples generation, and visualization and navigation of the knowledge map.

As the internet continues to grow, the quantity of information on the Web increases beyond measure. The internet users' abilities and requirements to use information also become varied and complicated. Ontology can describe correct meaning of web resource and relationships between web resources. And it can extract conformable information that a user wants. Accordingly, we need the ontology to represent knowledge. W3C announced OWL(Web Ontology Language), a meaning description technology for such web resources. But, the development of a professional use of tools that can compose and edit effectively is not yet developed adequately. In this paper, we design and implement an Ontology editor which generates and edits OWL documents through intuitional interface, with a OWL parser, a Internal DataModel, and a Serializer.

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 core technologies for intelligent services today are deep learning, that is neural networks, and parallel and distributed processing technologies such as GPU parallel computing and big data. However, for intelligent services and knowledge sharing services through globally shared ontologies in the future, there is a technology that is better than the neural networks for representing and reasoning knowledge. It is a knowledge representation of IF-THEN in RIF or SWRL, which is the standard rule language of the Semantic Web, and can be inferred efficiently using the rete algorithm. However, when the number of rules processed by the rete algorithm running on a single computer is 100,000, its performance becomes very poor with several tens of minutes, and there is an obvious limitation. Therefore, in this paper, we analyze the past and current studies on parallel and distributed processing of rete algorithm, and examine what aspects should be considered to implement an efficient rete algorithm.

유비쿼터스 컴퓨팅환경에서는 다양한 서비스가 존재한다. 사용자들은 수많은 서비스들을 사용하기에 앞서 이들이 어디에 있는지, 어떻게 사용해야 하는지를 알아야 한다. SLP, Jini, 그리고 UPnP 같은 대부분의 현존하는 서비스 디스커버리 (Service Discovery) 기술들은 키워드 매치 방법으로 서비스를 검색한다. 이 같은 방식에서는 사용자가 자신이 이용하고자 하는 서비스에 대한 정확한 명칭을 알고 있어야 서비스를 검색할 수 있다. 그러나 유비쿼터스 환경에서는 매우 다양한 서비스가 존재하고, 사용자들 대부분은 해당 서비스의 전문가가 아니기 때문에 정확한 키워드를 선택하여, 원하는 서비스를 찾는데 어려움이 있다. 시맨틱 웹 분야에서 새롭게 떠오른 온톨로지는 특정 분야에서 사용되는 정보의 구조 혹은 용어에 관한 내용을 사용자들이 공유할 수 있도록 정리해놓은 것이다. 본 논문에서는 이러한 온톨로지의 특성을 이용하여, 사용자에게 이용 가능한 서비스에 대한 정보들을 제공하여 사용자가 다양한 서비스를 쉽게 찾아 쓸 수 있는 방법을 제안하였다. 이 방식은 에이전트간의 온톨로지 교환을 통해서 이루어지며, 서비스 블록(Service Block)이라고 불리는 공간 안에서 수행된다. 또한 서비스 컨트롤러(Service Controller)를 이용하여 서비스를 쉽게 사용할 수 있도록 UI 를 제공한다. 본 시스템을 위하여 JENA2, JADE, Aglet, OWL, 그리고 RDQL 이 사용되었다.

In the 21st knowledge society, libraries should consider OPAC redesign and functional performance improvement by using new web related technology. This paper studied and analyzed case studies of Web 2.0. Library 2.0, domestic and international web portals and libraries. Based on the research, this study implemented Open API and RSS reader and proposes its utilization plan as a next generation OPAC 2.0 service model which can improve OPAC search results and search service.

Information visualization plays an important role to provide a conceptual comprehension of the information and should be adjusted and featured to reflect the characteristics of the domain to which it is applied. Product searching in e-Commerce is not an exception. In this paper, we present visualization techniques that are specified for effectively browsing the results of product searching. We considered visualization techniques including MapNet and Cluster Map and modified them to reflect the characteristics of the product domain. We consider two types of search queries: category searching and product property searching, and make it possible to include more detailed product semantics in their search criteria. We also provide a query refinement mechanism so that even users with rack of understanding the products may rewrite their queries for better results.
