This study explores the importance of semantic web-based network construction in art data archiving, as well as its meaning and value in the context of arts management along with its potential for future application. The study focuses on oral history obtained from the Arko Arts Archives that contained records of the lives and artistic views of early artists. In this study, the possibility of applying semantic web-based technology to materials concerning culture and the arts was discussed in five aspects based on the results of the case analysis. First, checking the relationship and discovering hidden artists are possible by revealing relationships between characters. Second, understanding and studying society and culture at a given time is possible by interpreting the contextual meaning of information. Third, art exploration can be done broadly and deeply, encompassing various genres from the perspective of the consumer. Fourth, through art construction, history can be reconstructed using a new and rich method. Fifth, expanding the scope beyond the boundaries of art is possible through convergence and collaboration of programs that handle big data. The network data can be used in various methods, such as art history research, art planning, and creation, throughout the art ecosystem. The results of the study suggest that digitizing a large quantity of data concerning culture and the arts is meaningful in arts management as well as identifying and analyzing the relationship network among data clusters using semantic web-based technology.

With the rapid development of information and communication technology, the speed of data production has increased rapidly, and this is represented by the concept of big data. Discussions on quality and reliability are also underway for big data whose data scale has rapidly increased in a short period of time. On the other hand, small data is minimal data of excellent quality and means data necessary for a specific problem situation. In the field of culture and arts, data of various types and topics exist, and research using big data technology is being conducted. However, research on whether basic information about culture and arts institutions is accurately provided and utilized is insufficient. The basic information of an institution can be an essential basis used in most big data analysis and becomes a starting point for identifying an institution. This study collected data dealing with the basic information of culture and arts institutions to define common metadata and constructed small data in the form of a knowledge graph linking institutions around common metadata. This can be a way to explore the types and characteristics of culture and arts institutions in an integrated way.

센서 네트워크에서의 에너지 효율적인 통신을 위한 infrastructure를 제공하고자 가상 백본(Virtu Backbone) 개념이 등장했다. 최근에는 트리 구조를 이용하여 가장 백본을 구성한 EVBT (Energy-aware Virtual Backbone Tree)가 제안되었다. 본 논문에서는 EVBT의 문제점을 개선한 m-EVBT(modified-EVBT) 생성 알고리즘에 대해 다룬다. EVBT와 달리 m-EVBT 생성 알고리즘은 백본 트리에 속하지 않은 센서 노드들의 업스트림 링크의 선정에 물리적 거리가 아닌 에너지 소모량 청보를 이용한다. 이 정보는 백본 트리를 만들 때 이용되는 ECR(EVBT Construction Request) 패킷에 포함되어 전송된다. 시뮬레이션을 통해 m-EVBT는 EVBT에 비해 데이터 전송시 에너지를 절약하고, 백본 트리 구축에 드는 추가적인 비용도 작다는 것을 확인할 수 있었다.

URI 중의성 해소 문제는 주어진 문서 내의 특정 단어에 연결 가능한 여러 URI가 주어졌을 때 진짜 URI 하나를 선택해내는 문제라고 할 수 있다. 이 문제는 다양한 해결법들이 존재할 수 있지만 기존에 연구된 문서의 문맥 간 유사도를 이용하여 해결하는 방법을 본 논문에서는 사용한다. 문맥 간 유사도를 이용하는 방법은 영어 디비피디아 URI spotting에서 TF*ICF방법으로 이미 연구가 되어있다. 본 논문에서는 Latent Dirichlet Allocation을 이용하여 URI 중의성 해소 문제를 다룰 것이며 그 범위를 한국어 디비피디아로 한정한다. 새로 제안하는 방법이 URI 중의성 해소 문제를 얼마나 잘 해결하며, 기존의 연구와 비교하여 얼마나 향상될 수 있는지를 분석한다. 또한 기존의 방법과 새로 제안한 방법 각자가 고유하게 풀 수 있는 문제가 존재함을 보이고, 두 방법을 병합하였을 때 보다 높은 성능에 도달할 수 있음을 전망한다.

The purpose of this study is to develop linked data of authority data in national archives of Korea as a cornerstone for linked data cloud of Korea. The study analyzed data structure of authority data as well as a retrieval system. It finally developed linked data based on RDF/OWL, Dublin Core, and SKOS. The study also employed TopBraid ComposerTM as a tool for ontology construction. The visualization of the tool provides users with flexible search and browsing between data as well as access of detail authority data. It complements the search of a current system in terms of flexible linking between records and authority data. The study also suggests future work to publish linked data of archival data set itself and make rich relationships among data in museums, libraries, and other archives.

Since the ad-hoc network allow nodes to communicate each other without infrastructure system and predefined configuration, it comes into the spotlight that is suitable to ubiquitous society. In ad-hoc network, route recovery mechanism is considered important. Normally route recovery is needed to solve the link failure problem because there is no route maintaining system like a router in ad-hoc networks. In this paper we propose BS-AODV(Bidirectional Searching-AODV) route recovery method. The proposed method is a local repair method that can be applied in all of the network area. Unlike a limited local repair method in AODV. the proposed method adopts the bidirectional searching method where the upstream/downstream nodes can send the route maintenance messages. Restricting the flooding of route request messages, the proposed scheme attempts to minimize the costs of local repair, the performance of the proposed scheme is evaluated through the simulations. In two scenarios which variate the node numbers and node speed, the comparison among the proposed scheme, AODV and AOMDV is shown in terms of the control traffic and data delivery ratio.

The research and development on Web of Data to realize the opening and sharing of diverse, heterogonous data on the Web has been actively accomplished. As a standard data model for this effort, LOD (Linked Open Data) based on ontology has been proposed. A specialized instance generation system is vital to the development of LOD-based system effectively. This paper implements i-Manager as an appropriate environment for the development of LOD instances, considering the requirements of LOD systems and the practical development environment of the diverse application domains. i-Manager separates the instance layer from the ontology layer by way of LOD Interface Sheet (LIS) and implements the specialized functions requested in LOD instance development, such as instance edit/store, visualization and SPARQL query processing. This paper proposes a new approach for LOD instance development, and i-Manager can be applied for the practical LOD development environment in the diverse application areas.

BIBFRAME, which is attracting attention as an alternative to the machine-readable catalog format (MARC) in the library world, presents a new bibliographic data model in the open web environment while maintaining compatibility with existing data. To convert KORMARC(Korean data model of MARC) records into BIBFRAME, we extract 25 key fields by analyzing the latest 5,000 bibliographic data from Nowon-gu Library in Seoul. The extracted core fields are classified into three types according to the compatibility of MARC 21, and define conversion rules for each type. In addition, implement an open source-based converter to perform KORMARC to BIBFRAME conversion. As a basic study on KORMARC to BIBFRAME conversion, this study is meaningful in that it analyzes the latest KORMARC information actually used, defines conversion rules, and attempts BIBFRAME conversion.

This study was to prepare a development plan for nationwide authority control system based on national authority sharing system of NLK through the survey targeting on libraries which do not participate in the system. Six plans were suggested to establish a nationwide authority control system based on this survey. First, an authority data construction module and a module linked to the national authority sharing system should be developed. Second, describing external identifiers such as ISNI to the national authority sharing system is to provides reliability of data and to utilizes to build linked data. Third, it is necessary to prepare strategies for promoting the national authority sharing system and diversifying services. Fourth, both authority establishment and non-establishment show difficulties and diversity in the selection and description of authorized access point, so it is necessary to prepare rules related to authorized access points. Fifth, since the data described in authority records is not enough, it is necessary to improve and upgrade authority records by using bibliographic records. Sixth, it is necessary to educate librarians about the necessity and function of authority control. As such, this study is meaningful in that it investigated the current status and requirements of libraries that do not participate in the nationwide authority system and sought ways to establish a nationwide cooperative authority control system.

UNESCO clearly has a good user interface compared to other sites. However, it does not have a structure in which user-centric knowledge curating is employed by users. As such, the knowledge structure should be expressed differently in advance for users to enjoy such benefits. At present, almost all current information systems are lacking with semantic and contextual information. Moreover, these systems are deemed insufficient of interlinking various kinds of thoughts in our minds. Thus, it is necessary to model in advance what users are likely to think and provide an interface that they can easily utilize based on that modeling. Furthermore, there is a need for a new structural theory based on semantic technology that can make that possible. Therefore, in this proposal, theoretical and practical insights were presented for user interface implementation to which relational facet navigation based on the structural theory is applied. Moreover, this proposal intends to suggest a "thinking expansion platform" that allows users' ideation of different concepts, including those unfamiliar to them.
