The purpose of this study is to suggest retrieval interfaces for Korean paintings which support users to retrieve specific digitalized images of them through various access points and to widely browse based on unique features Korean paintings. The study, first, develops a set of descriptive elements suitable for Korean Paintings. Twenty-six core elements and one hundred seventy-two attributes are selected as descriptive items for Korean paintings based on the opinion of 8 experts. Then, to gam realistic evidence of what descriptive elements of image serve users as access points, it is investigated which elements are used as retrieval access points among 26 core elements by 300 peered users who are consisted with two groups such as common users and domain specialists. The study, in final, designs two(general and advanced) types of search interfaces and display interfaces based on the most popular top 15 descriptive elements. This access-enhanced platform which enables user-oriented searches will satisfy users in image retrieving.

This study surveyed the retrieval systems for digital information resources of the university libraries in Busan, Ulsan, Gyeongnam districts and the vendors. Kinds of access points and retrieval conditions (Boolean logic, methods of index term identification, and particularities of the retrieval) of the libraries' systems are various and different to each other. Access points of the vendors' systems are unessentially various and different to each other, but the retrieval conditions are rather elaborated. Upon the result the suggestions for the standardization of digital information retrieval system are offered.

The authorized form is called the heading must be unique and consistent. Without both uniqueness and cosistency, retrieval from the bibliographic database will not be optimal and in some cases may even be impossible. But the authority control is extremely expensive, because it is labour-intensive and dependent on professional investigation and judgement. In fact, it is by far the most expensive function in all of bibliographic control. The processes used to determine the form of access points. maintain. use. and evaluate very accurate authority records reduce the efficiency to generate or merge bibliographic items without modification from any national level bibliographic utilities as well as individual library. In this paper non-authority control system was suggested to solve the disadvantages of authority work. The apparent advantages of the non-authority control system are it is easy to determine the heading, input the bibliographic data. integrate the access points into an existing file, and generate and merge bibliographic data without modification. In addition, non-authority control system can be transmitted into online information retrieval system conducted with a mixture of controlled vocabularies and natural language.

This study developed a name access point control system for better performance of information retrieval from institutional repositories, which are equipped with authorgenerated metadata processes for self-archiving. In developing name access point control data for the system, the primary data were created from the existing authority. However, unlike the existing authority data, the primary data did not use any authority forms. Instead, the data utilized all the forms provided by the resources as access points. Specifically, field of activity(subject) and title information on authorship were used to distinguish between persons who have the same name. The result showed that the system improved the performance of the information retrieval. The system has been also expected to be utilized over other metadata provided by libraries, in addition to the institutional repositories, in order to provide better quality information.

The effective searching for performing arts contents can be achieved by providing various access points and searching methods based on specialized metadata. The purpose of this study is to develop a faceted navigation interface which user could effectively and efficiently retrieve performing arts contents even if the users do not know accurate descriptive information about them. Therefore, the study, first, investigated search access points and navigation items providing by other the performing arts retrieval systems and to analyze information seeking behaviors of university students who major in music, dance and theater. And then, the study proposed the 36 facets with the 9 main facet categories suitable for performing arts and also proposed 27 descriptive elements suitable for performing arts contents. Finally, the study developed the performing arts contents retrieval system based faceted navigation interface with 3,360 experimental data and conducted an in-depth interview in terms of usability, serendipity, and efficiency. The applying the faceted navigations for searching performing arts contents will help users access and utilize them in the retrieval system and moreover satisfy user demands.

As information users seek multimedia with a wide variety of information needs, information environments for multimedia have been developed drastically. More specifically, as seeking multimedia with emotional access points has been popular, the needs for indexing in terms of abstract concepts including emotions have grown. This study aims to analyze the index terms extracted from Getty Image Bank. Five basic emotion terms, which are sadness, love, horror, happiness, anger, were used when collected the indexing terms. A total 22,675 index terms were used for this study. The data are three sets; entire emotion, positive emotion, and negative emotion. For these three data sets, co-word occurrence matrices were created and visualized in weighted network with PNNC clusters. The entire emotion network demonstrates three clusters and 20 sub-clusters. On the other hand, positive emotion network and negative emotion network show 10 clusters, respectively. The results point out three elements for next generation of multimedia retrieval: (1) the analysis on index terms for emotions shown in people on image, (2) the relationship between connotative term and denotative term and possibility for inferring connotative terms from denotative terms using the relationship, and (3) the significance of thesaurus on connotative term in order to expand related terms or synonyms for better access points.

While relevant studies emphasize the significance of user-oriented indexing associated with fulfilling both topical and non-topical needs of individual users, a great number of operational retrieval systems supports only those searches related to subject attributes of the users' needs. Retrieval systems for presidential image collections are not an exception for such a restriction. Upon this reality. this study seeks diversification of access points for presidential images based on descriptors directly presented by potential user groups. Improvements of subject-based descriptors are suggested based on those descriptors identified.

The purpose of this study was to investigate college students' preferences of Web-based OPAC retrieval techniques and their ABO blood types as an empirical survey. Data was collected through a self-designed questionnaire with a total of 101 undergraduate students from the College of Social Sciences responding. The collected data was analyzed using descriptive statistics, and One-way ANOVA. The results show that 'title' was most preferred among the access points, 'AND' was the most preferred Boolean operator, 'publication year' and 'subject' were the most favored techniques in limiting the scope of retrieval, and 'record number limit per page' was the most frequently used for displaying retrieval results. The results also show that there were little(3 out of 22, i.e. 13.6%) statistically significant differences between the college students' preferences of Web-based OPAC techniques and their blood type.
