Abstract
This paper describes a Web search optimization study that investigates both static and dynamic tuning methods for optimizing system performance. We extended the conventional fusion approach by introducing the “dynamic tuning” process with which to optimize the fusion formula that combines the contributions of diverse sources of evidence on the Web. By engaging in iterative dynamic tuning process, where we successively fine-tuned the fusion parameters based on the cognitive analysis of immediate system feedback, we were able to significantly increase the retrieval performance.Our results show that exploiting the richness of Web search environment by combining multiple sources of evidence is an effective strategy.
Abstract
This study worked on the qualitative analysis about nomenclature East Sea by the record type in researches related to East Sea shown in the scientific journals. Here in this study, the way of marking is classified as three: ‘sole notation of East Sea’, ‘sole notation of Sea of Japan’, and ‘simultaneous notation of both’. Based on a total of 4,192 selections from Web of Science DB, the analysis was followed up for change in time series by the notation type, notation type according to the nation that authors belong to, difference in research topic, impact factor, collaboration in research, and co-authorship network. The result turned out in this work that the sole notation of Sea of Japan accounted for the largest portion. It also showed that the rates of sole notation of East Sea and simultaneous notation have kept increasing continuously since the 1990s. Hub nations regarding the research of East Sea is five including Japan, Russia, Korea, USA, and China. In the case of sole notation of Sea of Japan, active collaboration studies are performed in USA, Russia, and China with a focus in Japan. In the case of sole notation of East Sea and simultaneous use, the research rate is relatively high in USA and Japan with a focus in Korea. As to the co-authorship network in the sole notation of Sea of Japan, sort of a “giant component” among different groups has been set up and through which the collaborative works are actively underway. However, it was found that the research of sole notation of East Sea is dispersed into small groups on the base of relevant individual institution.
Abstract
This study was implemented to suggest various indicators of collection evaluation for collection development policy in public libraries. For the sake of the exploratory research, this study tried to show the usability of indicators of collection evaluation through actual data of a case study. Also to analyze indicators of collection evaluation, this study used the ten years circulation records of the Gwangjin District Public Library in Seoul. Majors indicators of collection evaluation were the rate of use and use factor of purchasing books by annual, the rate of use and use factor of librarian’s recommended books by annual, the rate of non circulating books by annual, and the rate of use by residence annually.
Abstract
Library users must provide their personal information to libraries. This study surveyed these library users’ perception of privacy and the effect of the education after providing library user privacy education. As a result, first, it was found that after education, users were more interested in their privacy, rated the problem of library user privacy as more severe, and rated library user data collection as more likely to be considered privacy invasion. Second, we investigated users’ perception of how much user service records being collected in libraries violate users’ privacy, which showed a great perception change in 25 questions after the education. Third, in the survey about library and librarians’ efforts for protecting library user privacy, it was found that all 15 questions were rated as significantly more important after education. Fourth, library users have recognized that is necessary to process and handle the library record and are more sympathetic to the need for this procedure. Fifth, library users felt the possibility of a library record leak was a very serious threat.
Abstract
Personal Information Protection Act was first enacted in March, 2011, amended in September, 2011 and became effective. Nevertheless, the risk of interfering with personal information protection still remains, associated with collection, plagiarism, leakage, and even sales of personal information. The public libraries are not an exception. Accordingly, this study investigates the status of personal information protection in public libraries of Seoul and Gyeonggi province. Also, it tries to discover problems associated with the act and presents a model scheme to improve this situation. The scheme relates to ① securing of a sufficient budget; ② reinforcing professional education related to personal information; ③ developing detailed guidelines for public libraries.
Abstract
In the Korean wave 3.0 age, it is needed to prepare how to globalize and hold Korean culture through development of various Korean wave culture contents from existing contents focused on media. The goal of this study is to establish the foundation for developing the various Korean wave culture contents as linking information about other culture contents as well as food culture by extending Korean culture contents service based on LOD. For this purpose, this study established and assorted the concept of food culture through the literature review and case study and analyzed the applicability of the services of food culture contents based on LOD. Futhermore, this study provides the basis on extension of Korean wave culture service and suggests the process of implementation of food culture LOD and service model.
Abstract
The goal of this paper is to explore the field of Computer and Information Science with the aid of text mining techniques by mining Computer and Information Science related conference data available in DBLP (Digital Bibliography & Library Project). Although studies based on bibliometric analysis are most prevalent in investigating dynamics of a research field, we attempt to understand dynamics of the field by utilizing Latent Dirichlet Allocation (LDA)-based multinomial topic modeling. For this study, we collect 236,170 documents from 353 conferences related to Computer and Information Science in DBLP. We aim to include conferences in the field of Computer and Information Science as broad as possible. We analyze topic modeling results along with datasets collected over the period of 2000 to 2011 including top authors per topic and top conferences per topic. We identify the following four different patterns in topic trends in the field of computer and information science during this period: growing (network related topics), shrinking (AI and data mining related topics), continuing (web, text mining information retrieval and database related topics), and fluctuating pattern (HCI, information system and multimedia system related topics).
Abstract
The combined approach of using ego-centric network analysis and dynamic citation network analysis for refining the result of LDA-based topic modeling was suggested and examined in this study. Tow datasets were constructed by collecting Web of Science bibliographic records of White LED and topic modeling was performed by setting a different number of topics on each dataset. The multi-assigned top keywords of each topic were re-assigned to one specific topic by applying an ego-centric network analysis algorithm. It was found that the topical cohesion of the result of topic modeling with the number of topic corresponding to the lowest value of perplexity to the dataset extracted by SPLC network analysis was the strongest with the best values of internal clustering evaluation indices. Furthermore, it demonstrates the possibility of developing the suggested approach as a method of multi-faceted research trend detection.

Findings derived from this study, with regard to trends in research paper publishing by year, with regard to trends in research paper publishing by institution, with regard to trends in research paper publishing by author, with regard to trends in research paper publishing by area, and with regard to trends in research paper publishing by library type.
Abstract
The purpose of this study is to propose a management plan of the pop-up library model that is developed as part of the outreach library service recently. Especially this study focused the method for meeting the citizen’s right to know by providing various information of the pop-up library in social fields such as a national disasters. The survey and In-depth interview (a volunteer of Sewol ferry disaster and a participant of 2013 Busan International Film Festival) were done for this research. As the results of the investigation, the lack of communication and information between members in constrained situations were pointed pointed out as important problems. With these findings, this study suggested the pop-up library model management plan in information-constrained situations.
Abstract
The objective of this research was to quantitatively examine the uses of first person pronouns in academic journal paper abstracts. An approximate total of 144,400 abstracts that comprising of four disciplines (chemistry, computer sciences, social sciences, and medicine) from nine countries (China, Germany, India, Japan, South Korea, France, Spain, United Kingdom, and U.S.) were quantitatively examined. By exploring the use of first person pronoun in abstracts, this paper examined the current practices among academics in the world. The results indicate the norms of each author’s country and the norms of each discipline. Furthermore, the frequency-count result of this study contradicted viewpoints of academics who disapprove the use of personal person expressions in abstracts. An implication of this study is that there is a need for academics to acknowledge the uses of first person pronoun in the real world before forming personal opinions regarding the first person pronoun.
Abstract
This study aims to identify the characteristics of Korean secondary school students in perceptions on and needs to school libraries, and suggest an effective library management directions based on the characteristics. To achieve this purpose, we compare the perceptions on and needs for library elements, such as facilities, collections, programs, etc., between middle school students and high school students, and analyze the differences. Based on the results from the analysis, we suggest to establish an orientation of school library management. We also suggest a need of further study in which differences in the perception and needs among grades in a level of the secondary school for more detailed customization of library services.

Abstract
This study looks into how hearing-impaired college students use libraries and what their information needs are in order to prepare basic materials which would be applied for developing a library service program and others proper enough to be used by the hearing-impaired college students. In order to achieve the research goal, the study gathered data from a total of 155 hearing-impaired college students through a survey and interviews and a frequency analysis, a cross validation, a t-test and a one-way ANOVA were conducted to analyze the data. At the end of its research, the study confirmed that the hearing-impaired college students’ gender, years, degrees of disability, schools, specialties and prosthetic appliances would make significant differences in how the students use the libraries. In addition, the study took a look into differences in the hearing-impaired college students’ information needs caused by types of the students’ prosthetic appliances, schools and degrees of disability and found out that these types of the prosthetic appliances the students use would significantly affect every category of their information needs. The study now also understands that both the schools and the degrees of disability would make significant differences in a few categories of the information needs, and the former influences education and promotion targeting users and arrangement of sign language interpreters while the latter affects education and promotion targeting users and improvements in browsing environments.
