Comparison of social media use for the U.S. and the Korean governments

Abstract Social media allows for the creation of bottom-up online communities that encourage the government to utilize a two-way participatory media model, rather than a traditional broadcast media model. The purpose of this study is to examine the current status of social media usage in both Korean and U.S. governments, present several issues and suggest future directions.

Search engine optimization

Purpose – The purpose of this paper is to examine the effect of, and identify core techniques of, search engine optimization (SEO) techniques applied to the web (http://lg-sl.net) and mobile (http//m.lg-sl.net) Science Land content and services at LG Sangnam Library in Korea. Design/methodology/approach – In accordance with three major SEO guidelines, ten SEO techniques were identified and applied, and their implications were extracted on three areas: improved search engine accessibility, increased relevance between site content and search engine keywords, and improved site credibility. The effects were quantitatively analyzed in terms of registered search engine keywords and influx of visits via search engines. Findings – This study shows that SEO techniques help increase the exposure of the library services and the number of visitors through search engines. Practical implications – SEO techniques have been applied to a few non-Korean information service organizations, but it is not a well-accepted pract...

Design and users' evaluation of a topic maps-based Korean folk music retrieval system

The purpose of the study is to compare the performance between a Topic Maps-Based Korean Folk Music (Pansori) Retrieval System (TMPRS) and a representative Current Pansori Retrieval System (CPRS). The study is an experimental effort using representative general users. Participants are asked to carry out several predefined tasks and their own queries. The study measures objective and subjective performance of the two systems. The methods of data analysis are described and suggestions for improving current retrieval systems using Topic Maps are presented.

Building learning modules around the Competency Index for Linked Data

The Linked Data for Professional Education (LD4PE) project has developed a Competency Index for Linked Data that allows the construction of learning trajectories for Linked Data education. The Competency Index defines a set of assertions (within 30 groups under six categories) of the knowledge, skills, and habits of mind required for professional practice in the area of Linked Data. Educational resources have been collected and indexed with the competencies, all free for use. How can instructors, trainers, and learners use the competencies to build the learning outcomes in their curricula or course syllabi? How could they share and reuse the developed curricula and the instructional resources in teaching? This session aims to bring together educators and learners in an interactive venue for using the LD4PE tools to develop learning modules for their future audiences around the competencies. The outcome will be available to the broader community through the LD4PE website.

Study on the design and development of responsive plants information services

With the increased recognition of the importance of plant resources comes greater interest in plants information. However, there is lack of services that provide information that would offer in-depth knowledge on plants and continuously engage user interests. It would be desirable to develop a service that provides high-quality information on plants in tandem with relevant auxiliary data. This study aims to design and develop a responsive, Web-based service model in which gigapixel images of plants with culturally relevant information are integrated. Service usability in PC and mobile environments, and satisfaction levels against other similar services will be measured on service usage and user interviews will also be conducted to gain further insights on users’ need in this domain.

A study on the user evaluation for an RDA-based Korean bibliography retrieval system

Purpose – The purpose of this paper is to validate the usefulness of resource description and access (RDA) from user perspectives by implementing an RDA-based bibliographic retrieval system, and comparing it against two retrieval systems. Design/methodology/approach – Surveys and interviews were conducted to gather responses from 20 subjects who used the systems. Usability was measured according to the following metrics: search usefulness from search process and results; search efficiency, measured in time and the number of steps involved; general satisfaction for search results and process, and for information need; satisfaction for search functionalities, with five sub-measures (usability of functions of search tool, appropriateness of search results, usability of additional information, usability of associative relations, and appropriateness of search categories); and system convenience in terms of understandability and ease. Findings – The survey results indicate that all but the satisfaction for appr...

Topic Maps in the eHumanities

Topic Maps is a semantic technology for the integration of heterogeneous data and the convenient deployment of domain specific and semantically enriched web portals. Topic Maps is already widely in productive usage in industry and administration. We demonstrate with six projects the current usage and the opportunities of Topic Maps in the eHumanities. The projects are CeDECA from University of Pavia, RAMLine from the London Royal Academy of Music, Pansori Retrieval System from the Sungkyunkwan University Seoul, Musica migrans from the University of Leipzig, Collection of the Finnish National Gallery, and Text and Semantic from Signum in Pisa.

A new design structure for a classification system in Korean Traditional Performing Arts

Discussions of classification system design are limited to providing technical ‘recipes,’ lacking detailed “how-tos.” In addition, previous literature has addressed collaboration in classification system design; however, there has been a lack of discussion on how collaborative system design could be formed, or on the benefits and challenges that exist in system design. This study aims to introduce a generic design model of a collaborative classification system with technical ‘recipes’. A collaborative model for classification system design involves diverse stakeholders and describes how collaboration works throughout the design process. The limitations of the current discussion of classification system design and the value of collaborative design are investigated. The results of a case study in the field of Korean Traditional Performing Arts and a design structure adopted within that field are presented. It is also noted that a collaborative model adopts process analysis techniques from social process models. The paper discusses the benefits of collaborative design in relation to specifying roles and tasks of stakeholders as well as the challenges of collaborative design in classification system.

Ontology-driven knowledge organization — enhancing UDDI Web services in Korea using topic maps

Effective and efficient publishing and searching for Universal Description, Discovery and Integration (UDDI) Web services is important for the success of Web services. Traditional approaches such as index, thesaurus, and classification have historically dominated information representation and organization; however, they have some limitations. Ontology-driven knowledge organization [An ontology-driven knowledge organization approach] is considered one of keys to the next generation of knowledge management applications because ontology provides structure and meaning to data. This research examines how ontology-driven knowledge organization could provide benefits to current UDDI Web services.
