In the era of Web 2.0, users create a number of their own Web contents. So, multimedia search becomes much more important than ever. A tag is a simple keyword which describes the Web contents including URL, pictures, and videos. Tags perform a role of descriptors of Web contents and Web metadata properly. If the number of tagged Web data increases, users are more likely to find the desired search result because the system includes the Web contents which have richer Web metadata. However, the number of users who use tags as Web metadata is relatively small. Because of the cumbersome process of adding tags, or users do not know what to add for the better accessibility from the public. Given situation, tag recommendation, which helps the process of adding tags, has been studied to solve these problems. When a user adds some Web contents, the tag recommendation system recommends relevant tags for the Web contents to the use, and the user selects recommended tags. We analyze and categorize various tag recommendation algorithms in tagging system.

Previously, only one species belonging to the genus Apophua was recorded from South Korea by Kim (1955). Here, six additional species, A. cicatricosa, A. evanescens, A. honmai, A. stena, A. sugaharai and A. tobensis, are reported for the first time in South Korea. In this paper, we provide a key to the Eastern Palaearctic species of Apophua and diagnoses, as well as photographs of South Korean species.

Realty Trade Information Hanagement System(RTIMS) is intended to provide the services relat¬ed to realty business activity such as registration, search, negotiation, and information analysis. Introduction of the geographic information processing concept into the system has a great effect on the overall service processes of the realty business. This system is designed and implemented for remote users to easily get the informations about the target realty and to achieve a proper negotiation, by offering the various kinds of geographic informations including map, moving picture, photo, and so on. Futher, users can access RTIMS through WWW(World Wide Web) without additional client emulator.

최근 UCC의 등장으로 인터넷을 이용한 멀티미디어의 활용이 생활화되고 있다. 이러한 환경에서 사진, 동영상, 음악 등 멀티미디어의 검색은 시간과 접촉 이용성을 증가시켜줄 수 있는 중요한 이슈가 되고 있다. 그러나 현재 제안되어 있는 멀티미디어 활용 시스템들은 전체 사용자를 기반으로 우선순위를 적용하여 단일화된 metric을 통한 랭킹 시스템을 제안함으로 사용자 중심의 실용적인 랭킹 시스템을 제공하지 못하고 있다. 본 연구에서는 이러한 문제점에 기반하여 사용자 중심의 차별화된 뷰를 제공해 줄 수 있는 사용자 선호 기반(User Favor-Based) 멀티미디어 랭킹 시스템 '포토톡'을 제안한다. 제안하는 시스템은 현실적인 랭킹시스템을 통해서 사용자 중심의 결과를 도출할 수 있는 장점을 가진다.

In this paper, we introduce two retrieval methods for photos with speech documents. We compare the pattern of speech query with those of speech documents recorded in digital cameras, and measure the similarities, and retrieve photos corresponding to the speech documents which have high similarity scores. As the first approach, a phoneme recognition scheme is used as the pre-processor for the pattern matching, and in the second one, the vector quantization (VQ) and the dynamic time warping (DTW) are applied to match the speech query with the documents in signal domain itself. Experimental results show that the performance of the first approach is highly dependent on that of phoneme recognition while the processing time is short. The second method provides a great improvement of performance. While the processing time is longer than that of the first method due to DTW, but we can reduce it by taking approximated methods.
