According to a long-term master plan for the implementing of MOMAF's marine environmental informatization, we have developed marine environment portal web site which consists of 7 main-menu and 39 sub-menu including various types of contents (text, image and multimedia) based on RDBMS. This portal site was opened in Oct., 2002 (http://www.meps.info). Also, for the national institutions' distributed DB which is archived and managed respectively the marine chemical data and biological data, the integrated retrieval system was developed. This system is meaningful for the making collaborative use of real data and could be applied for data mining, marine research, marine environmental GIS and making-decisions.

본 논문에서 소개할 온라인 앨범 사이트는 텍스트 기반의 이미지 검색과 색상 기반 검색이 가능한 검색 엔진을 갖추었다. 기존의 검색 엔진들은 매우 단순한 키워드 매칭만을 통하여 이미지를 검색하여 그 결과 이미지와 사용자가 찾고자 하는 이미지 사이의 유사성이 낮은 경우가 많았다. SUMMIT(Sejong University MultiMedia Information Technology)은 등록된 각 사용자에게 개별 공간을 할당하여 사용자가 스스로 원하는 이미지를 업로드하거나 다운로드하게 한다. 또한, 각 사용자는 자신이 구성한 앨범 내에서의 키워드 검색과 내용기반 검색을 수행할 수 있으며 다른 사용자가 공개한 이미지나 시스템 데이터베이스에 저장된 이미지까지 포함한 포괄적인 검색 결과도 획득할 수 있다. 본 시스템은 각 사용자별 페이지 내에서의 검색이 가능하므로 검색의 정확도와 활용도를 높일 수 있다. 사용자는 SUMMIT에 올린 이미지나 타인이 공개한 이미지를 자신 혹은 기타 홈페이지에 직접 하이퍼링크할 수 있으며 어느 페이지에서도 같은 이미지 링크 태그를 사용할 수 있다는 용이함도 취할 수 있다.

Recent rise of social media channel is changing social and economic paradigm and is being used as an effective communication in marketing. The following research analyzes the most employed social marketing tools such as portal advertisement, blogs, and SNS channels to effectively execute social media marketing from performance indicator and ICSI perspective, analyzes each channel's characteristics and results based on Korea distribution companies' case studies and suggests a framework to effectively use each channel. Portal site advertisements are the most effective channel to draw customers with new information and are thus linked to profit by corporations with excessive budget and workforce. Blogs target a specific range of customers providing quality information and knowledge thus improving a corporation's and its product's trustworthiness, spread the word by allowing customers to scrap the information, form social groups and synthesize ideas, events, new contents and social involvement with loyal customers. SNS channels allow customers to get involved in real time information and events, grow through network by the power of customers, react immediately to customers' needs, and execute real-time market and customer reports. Though national corporations currently rely heavily on portal site advertisements, insightful marketing professionals are showing financial results with blog and SNS. In the future, based on a precise understanding of each channel's benefits and expected results, and with a focus on flexibility, timeliness and integrated use of each channel, a portfolio of dynamic marketing as a maximizing strategy could be synthesized.

웹을 이용하는 사용자들은 통상적으로 짧은 시간 내에 포탈의 여러 페이지를 방문하는 현상이 있는데, 이 때 방문하는 각 페이지 상에 위치 정보를 필요로 하는 콘텐츠(위치 기반 광고 배너, 위치 기반 날씨 등)가 존재한다면 웹의 특성상 짧은 시간 내에 동일 IP에 대한 위치 정보 검색을 반복하게 된다. 본 논문에서는 이러한 웹 사용 패턴을 캐시를 통해 반영한 고성능 인터넷 위치 검색을 제안, 구현하고 그 성능을 검증한 것이다. 이는 초당 2-3천 건 이상의 대용량 위치 정보를 검색을 수행하데 특히 적합한 방법으로, 적은 비용으로 위치 검색 성능을 획기적으로 높일 수 있었다.

This study examines coverage and coverage overlap of the three major Korean web directories, Naver, Yahoo Korea, and Empas. This study also suggests a methodology for collecting and processing web sites provided by these web directories. A method for napping main categories was developed. Each directory provided registered web pages in a slightly different way. Reference links had a significant influence on the coverage of each web directory. The overlap of pages among three directories was quite low, It is expected that this study could contribute to the field of web research by providing insights to how directories provide web pages and suggesting a methodology for the analysis of directory coverage.

This study examines web query types and topics submitted to Naver during one year period by analyzing query logs and click logs. Query logs capture queries users submitted to the system, and click logs consist of documents users clicked and viewed. This study presents a methodology to classify query types and topics. A method for click log analysis is also suggested. When classified by query types, there are more site search queries than content search queries. Queries about computer/internet. entertainment, shopping. game, education rank hightest. The implications for system designers and web content providers are discussed.

Recently, distribution of record via web and coefficient of utilization are increase. so, Archival information service using website becomes essential part of record center. The main point of archival information service by website is making record information retrieval easy. It has need of matching user's request and representation of record resources correctly to making archival information retrieval easy. Archivist and record manager have used various information representation tools from taxonomy to recent thesaurus, still, the accuracy of information retrieval has not solved. This study constructed record retrieval system based on Topic Map by modeling record resources which focusing on description metadata of the records to improve this problem. The target user of the system is general web users and its range is limited to the president related sources in the National Archives Portal Service. The procedure is as follows; 1) Design an ontology model for archival information service based on topic map which focusing on description metadata of the records. 2) Buildpractical record retrieval system with topic map that received information source list, which extracted from the National Archives Portal Service, by editor. 3) Check and assess features of record retrieval system based on topic map through user interface. Through the practice, relevance navigation to other record sources by semantic inference of description metadata is confirmed. And also, records could be built up as knowledge with result of scattered archival sources.

Transaction logs capture the interactions between online information retrieval systems and the users. Given the nature of the Web and Web users, transaction logs appear to be a reasonable and relevant method to collect and investigate information searching behaviors from a large number of Web users. Based on a series of research studies that analyzed Naver transaction logs, this study examines how transaction log analysis can be applied and contributed to the field of web searching and suggests future implications for the web searching field. It is expected that this study could contribute to the development and implementation of more effective Web search systems and services.
