Ten Web sites from educational policy authorities, educational research institutions, professional educational, and national libraries that provide educational policy information services are investigated using content analysis method. They are analyzed using various types of information sources, classification schemes, and functions of information retrieval. Standardization of classification scheme of educational policy information, standardization of meta data items, improvement of retrieval systems, provision of personalized information services to educational policy authorities, operation of specialized policy information centers, and cooperation among professional institutions are suggested. A model of a specialized educational policy information center is proposed.

The purpose of this study is to provide general principles to be used in designing university websites from the perspective of information architecture. Quantitative and qualitative evaluation criteria of web sites were developed based on information architecture principles. The students taking IA class were directly involved in constructing the evaluation criteria and they can be classified into four categories: 1) information organization; 2) navigation system; 3) labeling system; and searching system. These criteria were employed in evaluating twenty randomly selected university websites in Korea. General principles to be used in designing university websites were developed based on the findings of the study. They are composed of four major components in designing: 1) systematic information organization; 2) flexible navigation system; 3) consistent labeling system; and 4) efficient searching system.

인터넷 쇼핑몰과 같은 웹사이트에서 FAQ 검색의 중요성은 갈수록 증가되고 있다. 일반적으로 FAQ 검색을 하기 위해서 사용자가 직접 FAQ 리스트에서 FAQ를 찾거나 키워드 검색을 통해 FAQ를 찾는다. 하지만 이 방법은 FAQ 리스트를 찾는데 시간이 오래 걸리고 사용자가 만족하는 결과를 보여주지 못하는 경우가 많다. 이를 해결하기 위해 사용자의 자연어 질의에 대해 자동으로 FAQ를 찾아주는 FAQ 시스템이 필요하다. 자동화된 FAQ 시스템은 사용자의 질의 문장에 대해 FAQ 목록 중에 가장 유사한 FAQ 문장을 찾아준다. 이를 위해 각 문장을 유니그램과 바이그램 단어 집합으로 표현하여 문장 간의 유사도를 계산한다. 본 논문에서는 유니그램과 바이그램 단어 집합뿐만이 아니라 한국어 문형을 기반으로 한 문장 정규화를 통해 단어의 문장 성분 정보와 성분 내 위치 정보를 이용하여 문장을 표현함으로써 자동화된 FAQ 시스템의 성능을 향상 시키는 것을 목표로 한다.

The number of digital camera users is increasing rapidly and countless number of photos floats about on the internet especially through wide-spreading Cyworld and blogs. Though portraits cover a large percentage of those photos, because of the property rights, near entirety or such photos are unavailable for use by web-page producers, advertising companies, web-designers, and so on, who need a variety of portraits with differing expressions and characteristics. This study offers a search engine that incorporates image characteristics based on natural language index, which can provide a fast and reliable search result. It will create an opportunity for the digital photographers to mure easily sell their pictures and simultaneously provide the would-be users of the photos a better and easier way to find the pictures they are looking for. Once the search engine is realized, it will become possible to use not only the nouns as keywords and categories but also verbs in search of portraits revealing feelings, expressions, dressings, and other characteristics.

This paper focuses on the opinion information extraction and analysis system through Web mining that is based on statistics collected from Web contents. That is, users' opinion information which is scattered across several websites can be automatically analyzed and extracted. The system provides the opinion information search service that enables users to search for real-time positive and negative opinions and check their statistics. Also, users can do real-time search and monitoring about other opinion information by putting keywords in the system. Proposing technique proved that the actual performance is excellent by comparison experiment with other techniques. Performance evaluation of function extracting positive/negative opinion information, the performance evaluation applying dynamic window technique and tokenizer technique for multilingual information retrieval, and the performance evaluation of technique extracting exact multilingual phonetic translation are carried out. The experiment with typical movie review sentence and Wikipedia experiment data as object as that applying example is carried out and the result is analyzed.

To search based on the functional classification or provenance is not easy for users, and the key word-based information retrieval presents only simple words matching with the title of the records. The Presidential Archive of Korea developed a subject classification scheme to improve the convenience of searching for various records and came up with a subject thesaurus based on the scheme that utilizes the terms appearing on the title of the records and the terms used by the users who searched the portal or requested information disclosure. This research presents the development process of subject thesaurus. It also presents the utilization methods for records management work and services.

최근 인터넷 사용 증가는 물론 그에 따른 인터넷 사이트의 증가가 가히 폭발적이라고 할 수 있다. 전자상거래도 인터넷 사용증가에 힘입어 더욱 증가 추세에 있으며 관광산업 또한 예외는 아니다. 호텔에서도 웹사이트를 구축하여 온라인 예약과 각종 서비스에 필요한 정보를 제공하고 있으며 점차 온라인 예약이 증가추세이다. 하지만 인터넷 웹사이트의 급격한 증가는 풍부하고 다양한 정보를 제공한다는 긍정적인 면과 함께 정보과다(information overload)로 인해 정보 검색 등에 많은 시간과 비용이 요구되는 문제를 낳았다. 위와 같은 환경에서 사용자를 대신하여 원하는 정보를 찾아주는 역할을 수행하는 에이전트(agent)의 개념이 도입되었다. 현재 전자상거래 분야에서 활용 중인 에이전트는 구매자가 직접 판매자와 접촉하여 자신에게 필요한 여러 가지정보를 얻고 필요에 따라서는 협상 등을 진행한 후 최종 거래를 성사시키는 ‘사람과 사람간의 일 대 일 거래 과정’중 일부분만을 지원하고 있는 실정이다. 이와 같은 현존 에이전트의 문제점을 보완하기 위해서 구매자와 판매자를 대표하는 에이전트를 개발하고 이들 에이전트간의 직접적인 정보교환, 가격협상 및 이를 바탕으로 한 의사결정까지의 거래 모델을 수립하는 것이 필요하다고 인식된다. 따라서 본 연구는 인터넷상에서 구매자와 판매자간의 거래를 대행하는 인터넷 다중 에이전트(Internet Multi-Agents)의 개발을 위한 개념적 거래 모델을 연구하고, 이를 호텔 예약 분야에 응용하기 위한 각 에이전트의 필요 조건 및 기능을 제시하고자 한다.

A vast amount of the national college entrance information and a broad range of contents make it more difficult for user to find, collect and compare the data. In this study, we find out how users work to collect, compare data through the usability test and take cognizance of difficulty and requirements on national college entrance information web-site. And then we give the planning for designing national college entrance information web-site through a personalized information architecture(PIA) system. Namely, this paper provides a guideline for designing a user-centric personalized information architecture(PIA) system through the usability test.

The purpose of this paper is to explain and identify how atmospherics of web-sites such as graphics, colour, menu and link have an effect on consumers' emotion and satisfaction, which in turn have influence on repurchase intention in internet shopping malls. A survey study was conducted to collect the data with consumers who have experience purchase or search on internet shopping malls. Analysis of structural equation modeling with AMOS 18.0 was performed to test the research hypothesis. The results of the study are as follows: Menu and link are positively associated on consumers' emotion, but graphics and colour have not influence on both consumers' emotion and satisfaction. Consumers' emotion is positively associated on both satisfaction and repurchase intention, and then satisfaction is also positively associated on repurchase intention.
