The purpose of this study is to analyze the search pattern and search outcome of the National Central Library OPAC users by measuring their success rates and identifying the factors of failure and the personal background which bring about the differences of the search outcome. Various methods have been used for the study. Personal interview was used to find the pattern of the search, observation method was used to investigate the search process and the failure factors, and a questionnaire was used to survey personal background of searchers. The data were collected during the period of 7 days from April 17, 1995 through April 23, 1995. The search of 1, 217 cases, sampling systematically 25% out of the whole users, were collected and analyzed for the study. The findings of the study can be summarized as follows : First, in regard to the pattern, known-item search(72.6%) was preferred to the subject search(27.4%) and in case of known-item search the access point used were in the order of title, author, title and author. Second, the overall success rate of known-item search was 50.3% and the success rates were in order of author and date, title, and author. The failure factors of known-item search were divided into users factor of 67% and the database factor of 33%, respectively. Third, in case of subject search, its overall success rate was 44.1% and the keyword was the major access point, and the average of precision ratio was very low. Fourth, the analysis of the personal background related to the search outcome has shown significant differences by sex, the experience of using OPAC, education level, and the frequency of using other information retrieval systems. Based on the results the following suggestions can be made to improve the search outcome : First, the system should be su n.0, pplemented online help function to assist users to overcome the failure during search. Second, user instruction in group or individual should be implemented for the users to understand the system.

This paper presents a fusion approach to sentiment detection that combines multiple sources of evidence to retrieve blogs that contain opinions on a specific topic. Our approach to finding opinionated blogs on topic consists of first applying traditional information retrieval methods to retrieve blogs on a given topic and then boosting the ranks of opinionated blogs based on the opinion scores computed by multiple sentiment detection methods. Our sentiment detection strategy, whose central idea is to rely on a variety of complementary evidences rather than trying to optimize the utilization of a single source of evidence, includes High Frequency module, which identifies opinions based on the frequency of opinion terms (i.e., terms that occur frequently in opinionated documents), Low Frequency module, which makes use of uncommon/rare terms (e.g., "sooo good") that express strong sentiments, IU Module, which leverages n-grams with IU (I and you) anchor terms (e.g., I believe, You will love), Wilson's lexicon module, which uses a collection-independent opinion lexicon constructed from Wilson's subjectivity terms, and Opinion Acronym module, which utilizes a small set of opinion acronyms (e.g., imho). The results of our study show that combining multiple sources of opinion evidence is an effective method for improving opinion detection performance.

Traditional records information system has greatly improved accessibility to users by providing internet access to the digitized form of traditional records, access to which have previously been restricted for the purpose of preservation. This study investigated the accessibility and serviceability of Korean traditional records by examining current traditional record information systems in Korea. After compiling a list of traditional records information systems, which were grouped by operating agency, we analyzed them by coverage period, document type, and content format as well as examining search options and browse categories. We also categorized and examined the information systems by user type. The result showed that out of 105 traditional records information systems serving various content types and services, only a fraction(16.1%) provide a comprehensive information that includes bibliographic information, annotated description, content image, content text, and translated text, and less than a half(49.5%) provide a detailed search, all of which point to a less than optimal conditions for access to traditional records and suggest a strong need for improved traditional records information systems in Korea.

The critical strength of outsourcing system is to enhance the competitive power of the company by applying the centralization of management resources. This strategy has been used in library management and become the general method. The libraries in the U.S. stated to adopt the outsourcing system to organize the information of library works. Those in Korea also commence to use this method later on. The main reason of outsourcing the cataloging and classification works in the library was to reduce the budget; however, result were diverse. The efficiency on performing works was positive while the quality of bibliographic record was not guaranteed. Regardless of various opinions, The National Library of Korea decided to apply the method to cataloging and classification considered as a major work in maintaining library. This study is to analyze and criticize the decision made by The National Library of Korea.

Library catalogs are as a tool in order to satisfy the information needs of user but currently user's need is more complex and more diverse. Therefore, currently library catalogs do not meet the user's need and have some limitations. One of the ways for solving this problem will provide for the table of contents about monography. However recently, table of contents about books is builded individual library itself so the redundancy issue is pointed to waste of the cost of materials and human resources. Therefore, it should establish a standardized table of contents information DB and each of the related institutions can collaborate and share ways to be provided to take advantage of the table of contents. In order to this, central institutions should be provided a standardized way of building DB, provided conversion program, and mutual sharing principles associated with the building of table of contents DB.

Most university libraries in Korea have expanded the subscription of high-quality electronic resources in their amount and category, which are directly available to academic and research users via the web. Despite more than a decade's history, however, a lack of statistics made it difficult to get the overall pictures of electronic resources subscription status in Korea. The purpose of this study is to provide the analysis on nationwide statistics survey of how much money are spent on electronic resources, what kinds of subject resources are mainly subscribed, and how they are used and required by academic users, etc. Some comparisons are made with several factors that have effect on collection development of university libraries. This study will contribute to the future selection and subscription of electronic resources.

This study has been done to review the historical development of the cataloging system of books with emphasis on those in England and the U. S. The findings can be summarized as follows: (1) In 1844, Sir Panizzi invented what seems to be the first of its kind in history to list the inventory systematically at the British Museum. It is believed to be a complete system consisting of 91 articles. (2) A comparatively systematic system was developed in America by Jewett. in 1852. Composed of only 39 articles, the system is considered a renovative one worked out with due regard to the infrastructure of a library. (3) In 1876, a classic system based on a lexicographical order was set up by Cutter. Rated as the best one that was designed by an individual, the theory has since exercised widespreading effects on cataloging. (4) American and British library scientists collaborated in printing several editions of numerous volumes on the principles of classification, but they are not believed fully successful in establishing a consistent and compressive system. Their efforts found significance rather in their being the first international collaboration and setting a foundation upon which the international system of today has been developed. (5) The ALA Rule, published concurrently in ALA and LC in 1949, had two parts in its classification, the list of authors and that of titles. Its scientific classification has completed the cataloging of books in its developmental stage. (6) The 1967 American-British Rules integrated the cataloging systems published under separate covers by authors and titles. The system as well as the 1961 Paris System has greatly contributed to the standardization of bibliographical description throughout the English-speaking countries. The International Standard Book Description standardized Bibliographic system has enabled the librarians in different countries to exchange their bibliographical sources easily, helped to overcome the language barrier in listing and contributed to the efficient reading of bibliographical records through machines. (7) The second edition of the Angelo-American cataloging Rules, promulgated in 1978 under the influence of the international standard bibliographical description, was the one in which all the previous Rules were revised to have their strong points. The adoption of punctuation system to employ the computerized data processing and the standardization of description are expected to improve the cataloging system not only in the English speaking countries but in the Universal Bibliographic Control as well.

This study analyzed guidelines and instructions for access points representing works and expressions in RDA. The preferred title for the work is used as the basis for constructing an authorized access point to represent a work or expression. If applicable, the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity with principal responsibility for the work. The variant titles for the work are used as the basis for constructing variant access points to represent a work or expression. If the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity responsible for the work, the variant access points are constructed by combining the variant titles for the work to the authorized access point, and by using only the preferred title for the work. Besides, RDA provides instructions to construct the controlled access points for special works like musical works, laws, religious works and others, but the general principles for these works are same as the above instructions. The authorized access points for works and expressions in RDA are almost same as the main entry headings in AACR2.

Although BIBFRAME is recognized as a new bibliographic standard that can replace the existing MARC structure, the vastness of the descriptive items shows many limitations to be applied in library communities. Thus this study proposed separating the descriptive levels of BIBFRAME as a way to enhance the applicability of BIBFRAME. The descriptive level of BIBFRAME was divided into three stages: core, standard, and detailed levels based on the bibliographic area of ISBD 2011. This separation was semantically implemented using RDF/RDFS syntax. The levels of description in BIBFRAME was defined as Class Granularity and Class Element, and the Property Relation was defined for the linkage between the Classes defined and the BIBFRAME. By applying this syntactic structure, the relationships between the BIBFRAME descriptive items separated by each descriptive level could be linked with each other. This approach is expected to ensure applicability in the creation and sharing of bibliographic data using BIBFRAME.

This study is to suggest the concrete application plan of BIBFRAME under the development of BIBFRAME as library specific ontology for linked open data. The several research methods are used as the literature reviews, the case study of LC and LD4P, and the survey of cataloging librarians which is to grasp understanding level of the linked data related terms and requirements for constructing LOD. The application plan is suggested as follows. First, publishing name authority data and subject heading in LOD are prominent as the startup with creating terms list or vocabulary in LOD that has been used in library for controlled vocabulary and data value. Second, it is needed to develop BIBFRAME application and extension modeling in Korea, to map KORMARC and the properties and classes of BIBFRAME, and to develop the editor and MARC to BIBFRAME Transformation Tools. Third, the systematical training for cataloging librarians is designed to regard BIBFRAME related works as the librarian's main field. Therefore, this study would contribute to seek the practical application plan for BIBFRAME in Korea.
