Developing good methods for image description and indexing is fundamental for successful image retrieval, regardless of the content of images. Researchers and practitioners in the field of image indexing have developed a variety of image indexing systems and methods with the consideration of information types delivered by images. Such efforts in developing image indexing systems and methods include Panofsky's levels of image indexing and indexing systems adopting different approaches such as thesauri-based approach, classification approach. description element-based approach, and categorization approach. This study investigated users' perception of the objectiveness of image indexing, especially the iconographical analysis of image information advocated by Panofsky. One of the best examples of subjectiveness and conditional-dependence of image information is emotion. As a result, this study dealt with visual emotional information. Experiments were conducted in two phases : one was to measure the degree of agreement or disagreement about the emotional content of pictures among forty-eight participants and the other was to examine the inter-rater consistency defined as the degree of users' agreement on indexing. The results showed that the experiment participants made fairly subjective interpretation when they were viewing pictures. It was also found that the subjective interpretation made by the participants resulted from the individual differences in terms of their educational or cultural background. The study results emphasize the importance of developing new ways of indexing and/or searching for images, which can alleviate the limitations of access to images due to the subjective interpretation made by different users.

The traditional way of access to image information is through descriptive keyword searching. However, many studies in image indexing and retrieval have reached a consensus on the difficulties and limitations of text-base image description. This research investigates the feasibility of using visual browsing that is being used comparatively much less than keyword searching. The effectiveness of Keyword access versus visual access were examined through experiments in which participants searched for pictures of specified emotions using different access modes: keywords only, visual browsing only, and the combination of both. It was found that keyword searching was appropriate for clean searches while visual browsing was the effective way to browse many pictures quickly, thus finding more relevant pictures. Findings and results can guide of images retrieval systems, especially the retrieval system of subjective and interpretive information.

Compound noun phrase (CNP) is important factor for semantic information process because the meaning of the CNP is more disambiguous than that of single word. However, the CNP can be expressed in various types even though it expresses same meaning. It is called syntactic diversity. It makes information system difficult to grasp sense identity. In order to resolve the syntactic diversity in this research, we propose an indexing method for compound noun phrase. The main purpose is to make identical index term for various types of CNPs which has same meaning. To do so, the research follows next steps. For the first, we make rule template and utilize the template to extract CNPs from set of domestic research papers. In general, the CNP has a unique meaning. Considering the characteristic, we suggest synthesis rules of index terms and apply the rule to CNPs extracted in previous step. For the objective performance evaluation of the research, a test set, HANTEC 2.0, was utilized and the result was compared to baseline model. Through the experiment and the evaluation, we have confirmed that the indexing method suggested in this paper could positively affect retrieval precision and improve performance of the information retrieval.

The purpose of this study is to analyze how the changes of evaluation standards have affected Korean medical researchers' academic performance by comparing the publication status of medical articles both domestically and abroad. A total of 314,559 domestic articles in KMbase and 53,423 articles stored in MEDLINE published abroad by Korean researchers were analyzed. All of the data were compared per year according to the research field and indexed journals by numbers and proportions of articles published domestically and abroad. The analysis showed that the number of total articles and the proportion of articles published abroad increased continuously. In the early 2000s, articles published in Korea decreased, otherwise articles published abroad increased sharply. SCI articles showed a steady increase before 2000, and continued to increase over the next few years. KCI articles also showed a rapid increase in the early 2000s while other articles were decreasing. Publication trends shown in this study were similar despite quantitative and timely differences by research area. Performance evaluations focusing on SCI articles affected on quantitative decrease in the number of total articles published domestically. Quantitative growth itself is not an absolute indicator for academic achievement. Therefore, to complement any evaluation of academic achievement, qualitative analysis needs to be done as well.

This paper analyzes the film in a quantitative method to understand the principle to assign film's narrative as an art form. To do this, we tried to quantify 'conflict', which is a key factor of narrative, according to measuring the information represented in images. And thus, we measured the face areas of Protagonist and Antagonist, and then analyzed the relationship between area and conflict. The reason why the face area is used as the measurement target is because it is an index showing the way in which the director represents the conflict in the film. The quantification of conflict in films can be applied to indexing the narrative structure or specific conflict sections based on objective figures. In addition, it is possible to visualize narrative through conflict graphs, and it is meaningful that the computational criticism can apply into narrative study by quantification of conflict.

Finding aids are tools which facilitate to locate and understand archives and records. Traditionally there are two types of archival finding aids: vertical and horizontal. Vertical finding aids such as inventories have multi-level descriptions based on provenance, while horizontal ones such as catalogs and index are tools to guide to the vertical finding aids based on the subject. In the web environment, traditional finding aids are evolving into more dynamic forms. Respecting the principles of provenance and original order, vertical finding aids are changing to multi-entity structures with development of ISAD(G), ISAAR(CPF) and ISDF as standards for describing each entity. However, vertical finding aids can be too difficult, complicated, and boring for many users, who are accustomed to the easy and exciting searching tools in the internet world. Complementing them, new types of finding aids are appearing to provide easy, interesting, and extensive access channels. This study investigates the development and limitation of vertical finding aids, and the recent trend of evolving new finding aids complementing the vertical ones. The study finds three new trends of finding aid development. They are (i) mixture, (ii) integration, and (iii) openness. In recent days, certain finding aids are mixed with stories and others provide integrated searches for the collections of various heritage institutions. There are cases for experimenting user participation in the development of finding aids using Web 2.0 applications. These new types of finding aids can also cause some problems such as decontextualised description and prejudices, especially in the case of mixed finding aids and quality control of user contributed annotations and comments. To solve these problems, the present paper suggests to strengthen the infrastructure of vertical finding aids and to connect them with various new ones and to facilitate interactions with users of finding aids. It is hoped that the present paper will provide impetus for archives including the National Archives of Korea to set up and evaluate the development strategies for archival finding aids.
