Influence of Interfaces on Novice Users' Performance in Social Virtual Worlds
Jung, Yoonhyuk ; Ju, Boryung ; Zach, Lisl ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 7~23

This paper explores how interface environments have an influence on novice users' performance in social virtual worlds (SVWs), which are emerging user-centric three-dimensional cyberspaces. Despite their early popularity, SVWs have experienced that numerous new users leave the cyberspaces soon before they become long-term users. One possible reason is that unfamiliar interfaces of SVWs can be a barrier to novice users' adaptation of the technology. To understand a role of interfaces in the users' assimilation of SVWs, we examine an impact of three interface factors (presence, affordance, and feedback) on performance which is regarded as a yardstick for users' adaptation of SVWs. Forty participants were recruited and went through one-hour experimental sessions with seven tasks in Second Life; they were also asked to answer a questionnaire. Findings indicate that while affordance and feedback are significant factors influencing novice users' performance, presence has no impact on their performance.

Recently libraries are experiencing an increasing number of difficult patrons because of the increase in the unemployment rate and the problem of mental health in their communities. The problem behaviours of difficult patrons have negative influence to other users and staff in the library. This seems closely associated with the decline in the quality of library services. Therefore, in this study, we developed a how-to-do-it manual for library staff to meet the aforementioned challenges and to enhance the overall quality of library services for both general users and difficult patrons.
A Rule-based Approach to Identifying Citation Text from Korean Academic Literature
Kang, In-Su ;

Identifying citing sentences from article full-text is a prerequisite for creating a variety of future academic information services such as citation-based automatic summarization, automatic generation of review articles, sentiment analysis of citing statements, information retrieval based on citation contexts, etc. However, finding citing sentences is not easy due to the existence of implicit citing sentences which do not have explicit citation markers. While several methods have been proposed to attack this problem for English, it is difficult to find such automatic methods for Korean academic literature. This article presents a rule-based approach to identifying Korean citing sentences. Experiments show that the proposed method could find 30% of implicit citing sentences in our test data in nearly 70% precision.
Assessing e-Book Success Model based on the Information System Success Model
Oh, Chang-Gyu ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 61~82
DOI : 10.3743/KOSIM.2012.29.4.061
With the proliferation of the e-Book industry, people are increasingly interacting with e-Book as information systems. While e-Book contains the components regarded as an information system(IS), few studies have been conducted to assess the success of e-Book from IS perspective. This study proposed and empirically evaluated an e-Book success model. Structural equation modeling techniques were applied to the data collected by questionnaire from 241 users of e-Book. Every relationship among constructs was significantly supported by the data. This finding provided theoretical implications to extend existing e-Book research into the broader IS research area. Furthermore, this study illustrated the use of multi-group structural analysis to test the differences in structural weights between high e-Book and high paper book utility groups. The managerial implications of the results in setting different relationships and allocating appropriate paths to vitalize the e-Book market were discussed.
Undergraduates' Use of Social Media for Health Information
Kim, Soojung ; Oh, Sanghee ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 83~99
DOI : 10.3743/KOSIM.2012.29.4.083
The present study surveyed 225 undergraduates to examine their social media use behaviors and their perceptions of usefulness, trustworthiness, and privacy of social media for seeking and sharing health information. 151 respondents reported using social media for health information while 74 reported not using it for health matters. Results show that the most popular medium were social Q&As, followed by blogs and social networking sites. Age, gender, school year, and the presence of a health problem were associated with the social media use behaviors. This study suggests the potential of social media as a desired channel for providing health information to undergraduates.
Design and Implementation of Tag Coupling-based Boolean Query Matching System for Ranked Search Result
Kim, Yong ; Joo, Won-Kyun ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 101~121
DOI : 10.3743/KOSIM.2012.29.4.101
Since IR systems which adopt only Boolean IR model can not provide ranked search result, users have to conduct time-consuming checking process for huge result sets one by one. This study proposes a method to provide search results ranked by using coupling information between tags instead of index weight information in Boolean IR model. Because document queries are used instead of general user queries in the proposed method, key tags used as queries in a relevant document are extracted. A variety of groups of Boolean queries based on tag couplings are created in the process of extracting queries. Ranked search result can be extracted through the process of matching conducted with differential information among the query groups and tag significance information. To prove the usability of the proposed method, the experiment was conducted to find research trend analysis information on selected research information. Aslo, the service based on the proposed methods was provided to get user feedback for a year. The result showed high user satisfaction.

Yang, Myung-Seok ; Kang, Nam-Kyu ; Kim, Yun-Jeong ; Choi, Kwang-Nam ; Kim, Young-Kuk ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 123~142
DOI : 10.3743/KOSIM.2012.29.4.123
To develop an intelligent search engine to help users retrieve information effectively, various methods, such as Semantic Web, have been used, An effective retrieval method of such methods uses ontology technology. In this paper, we built National R&D ontology after analyzing National R&D Information in NTIS and then implemented National R&D Knowledge Map to represent and retrieve information of the relationship between object and subject (project, human information, organization, research result) in R&D Ontology. In the National R&D Knowledge Map, center-node is the object selected by users, node is subject, subject's sub-node is user's favorite query in National R&D ontology after analyzing the relationship between object and subject. When a user selects sub-node, the system displays the results from inference engine after making query by SPARQL in National R&D ontology.
Big Deal, Open Access, Google Scholar and the Subscription of Electronic Scholarly Contents at University Libraries
Shim, Wonsik ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 143~163
DOI : 10.3743/KOSIM.2012.29.4.143
The dominant model of acquiring scholarly contents at academic libraries is so called big deal where libraries subscribe to a bundle of hundreds, if not thousands of journals in a multi-year contract with fixed annual rate increase. The bid deal, started in the mid-1990s, offered a number of advantages for academic libraries and their users. However, escalating prices for these packages have become a serious issue casting doubts about the sustainability of the subscription-based model. At the moment, it appears there is no viable alternative other than pay-per-view method that is being tested at some libraries. Libraries' budget situation will remain a key factor that might change the situation. Open access started in the 2000s as a vehicle to eliminate barriers to publishing and distributing peer-reviewed scholarly journal articles. Open access publishing is witnessing two-digit growth annually. Open access articles now occupy close to 20% of two major citation databases: Scopus and Web of Science. Google Scholar service, debuted in late 2004, is now a popular tool for discovering and accessing scholarly articles from a vast selection of journals around the world. There is a call for taking Google Scholar seriously as a potential replacement of library databases amid concerns regarding the quality of journals indexed, limited search capabilities vis-
-vis library databases, and monopoly of public goods. Escalating budget problems, rapid growth of open access publishing and the emergence of powerful free tool, such as Google Scholar, need to be taken seriously as these forces might bring disruptive changes to the existing subscription-based model of scholarly contents at academic libraries.
A Study on the Current State of Online Subject Guides in Academic Libraries
Kim, Soojung ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 165~189
DOI : 10.3743/KOSIM.2012.29.4.165
This study investigated the current state of online subject guides in Korean academic libraries and suggests improvement. Through the examination of 100 academic libraries' Web sites, only 14 online subject guides were identified, showing that the development of online subjects guides in Korea is still in infancy. The examined online subject guides were evaluated as high quality in terms of accessibility, integration of information resources, and format consistency, but low quality in the provision of specialized subjects, user instruction, and information retrieval systems. An online subject guide should be a one-stop service that provides fast access to information resources along with subject-specialized user instruction and effective communication with librarians.
Investigating an Automatic Method for Summarizing and Presenting a Video Speech Using Acoustic Features
Kim, Hyun-Hee ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 191~208
DOI : 10.3743/KOSIM.2012.29.4.191
Two fundamental aspects of speech summary generation are the extraction of key speech content and the style of presentation of the extracted speech synopses. We first investigated whether acoustic features (speaking rate, pitch pattern, and intensity) are equally important and, if not, which one can be effectively modeled to compute the significance of segments for lecture summarization. As a result, we found that the intensity (that is, difference between max DB and min DB) is the most efficient factor for speech summarization. We evaluated the intensity-based method of using the difference between max-DB and min-DB by comparing it to the keyword-based method in terms of which method produces better speech summaries and of how similar weight values assigned to segments by two methods are. Then, we investigated the way to present speech summaries to the viewers. As such, for speech summarization, we suggested how to extract key segments from a speech video efficiently using acoustic features and then present the extracted segments to the viewers.
A Preliminary Study on the Development of Library R&D Policy Agenda
Lee, Soo-Sang ; Rho, Jee-Hyun ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 209~227
DOI : 10.3743/KOSIM.2012.29.4.209
This study intends to develop R&D policy agendas that are required to prepare a smart library/smart society in Korea libraries. To the end, methodology was established to explore policy issues and agenda for library R&D, and the preliminary agendas were drawn from informetrics, subject analysis, and brainstorming techniques. Then, the preliminary agendas were revised through supplementary works, such as the comprehensive investigation into research papers and the recent research projects. Based on the results, evaluation for the R&D agendas was performed. The Analytic Hierarchy Process (AHP) method was used as a structured technique for analyzing the importance and the priority of the agendas. This study can be used for improving and/or expanding quality of information services in Korean libraries and for exploring the requirements to play a crucial role in the future society.
An Analysis on the Conception of Web Navigation in Library and Information Science Research
Park, Heejin ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 229~249
DOI : 10.3743/KOSIM.2012.29.4.229
The study aims to analyze the notion of web navigation in library and information science (LIS) by investigating the concepts and its consequences. The analysis is based on 32 articles published in international LIS journals between 1995 and 2012. The study noted the changing contexts of information retrieval in the Web environment, and discusses the changes over time in the way in which the notion of navigation have been regarded. Three main concepts are identified: navigation behavior, navigation strategies, and navigation designs.
Developing Subject Headings for Children's Picture Books based on A to Zoo
Park, Ziyoung ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 251~271
DOI : 10.3743/KOSIM.2012.29.4.251
Subject headings support the effective access of children's picture books. However, it is difficult to select subject terms from titles or table of contents in children's picture books because of their relatively little textual information. Therefore, it is necessary to assign subject terms to each picture book. However, it is not adequate to use general subject headings because the types and levels of general subject headings are different from special subject headings for the children's materials. For this reason, this study aims to develop subject headings for children's picture books. The subject terms in A to Zoo were selected, and the selected terms were translated into Korean and modified for the Korean culture and language. Other reference books, such as Elementary Korean Dictionary, were also used to determine adequate terms for children. The resulting subject headings were assigned to the recommended picture books for children and used to search by subject, browse, and recommend books.
An Approach Toward Image Access Points based on Image Needs in Context of Everyday Life
Chung, EunKyung ; Chung, SunYoung ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 273~294
DOI : 10.3743/KOSIM.2012.29.4.273
Images have been substantially searched and used due to not only the advanced internet and digital technologies but the characteristics of a younger generation. The purpose of this study aims to discuss the ways on expanding the access points to images by analyzing the needs of users in context of everyday life. In order to achieve the purpose of this study, 105 questions of image seeking in NAVER, which is one of social Q&A services in Korea, were analyzed. For the analysis, a two-dimensional framework with image uses and image attributes were utilized. The findings of this study demonstrate that considerable use purposes on data oriented pole, such as information processing, information dissemination and learning are identified. On the other hand, image attributes from the needs of image show that non-visual aspects including contextual attributes are recognized substantially in addition to the traditional semantic attributes.
Ego-centered Topic Citation Analysis on Folksonomy Research Documents
Lee, Jae Yun ;
Journal of the Korean Society for information Management, volume 29, issue 4, 2012, Pages 295~312
DOI : 10.3743/KOSIM.2012.29.4.295
This research aims to present the ego-centered topic citation analysis, which is a new application of White's ego-centered citation analysis, for analyzing multilayered knowledge structure of a subject domain. An experimental topic citation analysis was carried out on the folksonomy research documents retrieved from Web of Science. Ego-centered topic citation analyses on folksonomy research domain were conducted in three stages: ego-documents set analysis, topic citation identity analysis, and topic citation image analysis. The results showed that the ego-centered topic citation analysis suggested in this study was successfully performed to illustrate the inner and the outer knowledge structures of folksonomy research domain.
