이용자 정보이용환경이 웹으로 변화하면서, 기록관리기관들도 종전보다 더 많은 서비스를 웹을 통해 제공하고 있다. 이 연구는 국가기록원 웹사이트를 이용하는 이용자의 최근 유입경로와 10년 반 동안 매달 상위 100개의 검색어 데이터를 분석하고 그에 맞는 기록정보서비스방안을 제시한다. 분석 결과 유입경로는 크게 포털 사이트별 접속, 국가별 접속, 유사기관 별 접속 및 모바일 접속으로 분류할 수 있었다. 이용자들의 검색어를 분석한 결과 이용자들이 10년 반 동안 가장 많이 검색한 검색어는 '토지조사부'였으며, 꾸준한 관심을 갖고 검색한 검색어 또한 '토지조사부'였다. 그 외에 정부 기관에서 생산한 문서 또는 관보에 대한 관심도 높음을 확인하였다. 그리고 이용자들이 가장 많이 검색한 검색어와 꾸준히 등장한 검색어를 파악한 결과, 검색어들을 크게 토지, 일제강점기, 6.25 전쟁과 남북관계, 기록관리 및 이용으로 묶어볼 수 있었다. 분석결과를 토대로 포털 사이트 및 모바일 등을 활용한 국가기록원 웹사이트의 연계성 강화와 검색 서비스의 고도화 방안을 제안하였다. 이 연구는 이렇게 웹로그나 이용자 검색어 등을 분석하면 기록관리기관 이용자들에게 제공하는 서비스를 고도화할 수 있는 의미 있는 결과를 얻을 수 있음을 확인하였다.

In this paper, we propose a meta-search engine which provides distributed product information through a unified access to multiple e-commerce. The meta-search engine proposed in this paper performs the following functions: (I) The user is able to create a category-based user query, (2) by using the WordNet, the query is semantical refined fined for increasing search accuracy, and (3) the meta-search engine recommends an e-commerce site which has the closest product information to the user's search intention, by matching the user query with the product catalogs in the e-commerce sites linked to the meta-search engine. An experiment shows that the performance of our model is better than that of general keyword-based search.

국내 1위 인터넷포털 사업자인 네이버는 사용자가 지정하는 키워드가 특정 기간 동안에 네이버에서 얼마나 자주 검색되었는지에 관한 피검색빈도자료를 제공한다. 본 연구는 네이버의 피검색빈도자료를 활용하여 기업명의 피검색빈도와 그 기업의 미래 주식수익률과의 관계에 대해 분석하였다. 그 결과는 다음과 같다. 첫째, 기업명의 피검색빈도는 극단적 수익률 및 거래회전율과 같은 기존의 투자자 관심(investor attention)변수와 중복되지 않는 새로운 투자자 관심변수이다. 둘째, 금주의 피검색빈도가 높은 기업일수록 그 다음 주의 주간수익률이 높다. 셋째, 피검색빈도가 높은 기업은 이후에도 수익률 반전현상이 관찰되지 않으므로, 피검색빈도는 해당 기업에 대한 본질적 정보를 포함하는 것으로 볼 수 있다. 넷째, 피검색빈도가 주식수익률에 미치는 영향은 시장 수준의 투자자 관심사건(market-wide attention grabbing events)이 발생한 이후 더욱 강하게 나타난다.

In the Web 2.0, besides more gaining information on the web, the number of web sites that take advantage of RSS increases explosively. Commonly each users search RSS channels through the web search engine before registering RSS channel's url to the RSS reader. Users judge whether the site is RSS channel or not and register an RSS channel's url through theirs interests. Because accomplished by users themselves, those processes conflict to user's convenience and quick consumption of information. Techniques of current search engines can't provide users with reliable RSS feed information as search results. In this paper, we analysis appropriateness of current search engines' techniques that offer users RSS feed search service and discuss their limitations. Also, we make up RSS feed database through classification of RSS tag being possible to search RSS feed information effectively and apply update rate of each RSS channel's feed to ranking algorithm providing more reliable search results.

This study was carried out to investigate the utilization status of internet dietary information by gender(boys: 363, girls: 366) in adolescent(middle & high school students). The results were summarized as follows. The internet using frequency of 6-7times per week had 45.0% of subjects and the using time of internet per a time was shown mainly'<2hours(68.5%)'. The main place for internet use was home(79.0%) and favorite search engine was 'Yahoo'(45.7%) and 'Daum'(19.3%). As main purpose using internet were mentioned 'social intercourse'(45.0%) and data search'(24.8%). The organization that offer to reliable internet information was educational institution'(49.4%). The problems in using information site were 'poor information'(26.4%), 'slow connection speed'(22.6%), and 'don't arouse interest'(18.8%). The search experience about dietary information had only 27.9% of subjects and search purpose was 'for homework'(33.3%) and 'for health'(32.0). The satisfaction degree of dietary information was not high. The connection motive to dietary information was mainly 'by site navigation casualty'(55.7%). Only 7.7% of subjects had experience of nutrition counseling using internet, and the motive of nutrition counseling was also 'by site navigation causally'(55.8%). The purpose of counseling was 'for diet'(41.5%) and 'for health problem'(30.2%), and the satisfaction degree of counseling result was very low. As the ask of improvement for counseling site were pointed out 'poor in answer content'(44.8%) and 'lazy answer'(31.0%). The subjects wanted to get the dietary information about 'growth in status'(41.4%), 'diet related skin beauty'(14.6%), the update period less 1 month, and the way of 'free board'(32.3%), 'game'(21.1%) and 'animation'(19.3%) as offer tool. The results of this study showed that although the internet using percent and frequency of subjects was high, they used dietary information very seldom and they are dissatisfied with internet nutritional information. Therefore, the information donor should consider which dietary information was needed and what is the optimal tool for adolescent.

Recently various of information suppliers provide information via WWW so the necessary of search engine grows larger. However the efficiency of most search engines is low comparatively because of using simple pattern match technique between user's query and web document. And a manifest contents of query for special expert field so much worse A specialized search engine returns the specialized information depend on each user's search goal. It is trend to develop specialized search engines in many countries. For example, in America, there are a site that searches only the recently updated headline news and the federal law and the government and and so on. However, most such engines don't satisfy the user's needs. This paper proposes the specialized search engine for ocean information that uses user's query related with ocean and search engine uses the association rules in web data mining. So specialized search engine for ocean provides more information related to ocean because of raising recall about user's query

This study was performed in two ways, which are 'Before' 'After' carrying out trench search through GPR which is called 'Non Destructive Geophysical' to the expected area where the remains of historic interest could be distributed within the construction site from Dae-gu to Busan. As a result, the layer containing gravel and sand has more irregular specular surface then others containing silt and clay. And, this paper, irregular specular surfaces of prominence and depression patter appeared. After performing trench search, verified that the site yield dolmens and lots of stone implements.

This paper empirically analyzed consumer price search behavior using Web log data of a Korean web site for price comparison. Consumer click-stream data of the site was used to test the effects of price level, product category, third party certification, reputation of retailers on click behavior. According to the descriptive statistics, 67.4% of shopbot users clicked the offer which was the lowest price returned in a search. We found that third party certification and reputation of retailers were significant determinants of clicking the lowest priced offer from legit analysis. We also applied Tobit regression analysis to estimate the price premium of the two determinants, but only reputation of retailers was found to have price premium of 4.9%.

The performance of a distributed database system depends particularly on the site-allocation of the fragments. Queries access different fragments among the sites, and an originating site exists for each query. A data allocation algorithm should distribute the fragments to minimize the transfer and settlement costs of executing the query plans. The primary cost for a data allocation algorithm is the cost of the data transmission across the network. The data allocation problem in a distributed database is NP-complete, and scalable evolutionary algorithms were developed to minimize the execution costs of the query plans. In this paper, quadratic assignment problem heuristics were designed and implemented for the data allocation problem. The proposed algorithms find near-optimal solutions for the data allocation problem. In addition to the fast ant colony, robust tabu search, and genetic algorithm solutions to this problem, we propose a fast and scalable hybrid genetic multi-start tabu search algorithm that outperforms the other well-known heuristics in terms of execution time and solution quality.

포털사이트는 검색엔진을 넘어 사이버스페이스 자체를 의미할 정도로 개념과 영역이 확대되었다. 일반인들뿐만 아니라, 필요로 하는 학술정보가 서비스되기 때문에 연구자도 포털사이트를 많이 이용한다. 그동안 포털의 검색은 얼마나 많은 정보를 검색하게 해 줄 것인가 하는 양적인 면에 관심을 두었다. 그러나 최근에는 검색의 질에 보다 관심이 많아지고 있다. 이 논문은 포털이 제공하는 학술정보검색의 문제점을 분석하고, 비교적 신뢰성을 인정받는 사전 서비스와 학술정보를 연계함으로써 학술정보검색의 질을 향상하기 위한 시범적인 시도이다. 즉, 검증되고 압축적으로 정리된 사전의 표제어와 해당 표제어를 키워드로 하는 권위 있는 연구 성과를 연계시킴으로써, 사전을 검색할 때 주제어 관련 연구 성과까지 검색할 수 있게 하는 방안을 제시하고자 한다.
