인터넷 포털 사이트는 단순한 검색엔진을 넘어 네티즌들이 항해하는 사이버스페이스 그 자체를 의미할 정도로 영역과 개념이 확대되었다. 일반인들뿐만 아니라 전문 연구자도 필요로 하는 학술정보를 포털 사이트에서 서비스하기 때문에 포털 사이트를 많이 이용한다. 그 동안 포털의 검색은 얼마나 많은 정보를 검색 결과로 제시해 줄 것인가 하는 양적인 면에 관심을 두었다. 그러나 최근에는 검색의 질적인 측면에 보다 많은 관심이 주어지고 있다. 이 논문은 포털에서 제공하는 전문 학술정보 검색의 문제점을 제시하고, 주제어 사전 서비스와 연계하여 보다 신뢰성 높은 학술정보를 검색할 수 있게 하기 위한 시범적인 시도이다. 즉, 검증되고 압축적으로 정리된 사전의 표제어와, 해당 표제어를 키워드로 하는 권위있는 연구 성과를 같이 연계시킴으로써, 사전을 검색할 때 연구 성과까지 검색할 수 있게 하여, 검색의 효율성과 정보의 신뢰성을 높일 수 있는 방안을 제시하고자 하였다.

In terms of science learning for students and of scientific literacy for the general public, understanding science terminology is very important. Aside from the science language education delivered in schools, we assumed that supplementary materials are necessary to search and study the meaning of science terminologies for students or the general public. This study aims to investigate whether explanation texts of portal dictionary, Pyojun Korean Dictionary, and science textbooks are easy to read or understand for students and how the students perceive the explanations they present. The results show that science textbooks are easier to read and understand for students than the portal dictionary or Pyojun Korean Dictionary. However, all three materials have very low level of readability compared with students' average level. There definitely are rooms for improvement to increase their readability.

Internet portals have been revolutionized not only as simple search engines but also as a new space for the Internet users. They have developed to give satisfying search results for academic information users. academic fields. However, their attention was given to the quantity rather than the quality of the results. This tendency is now changing. This study addresses the problems in the search process using the current portal sites and presents an integrated scholarly information service where users can access more organized and trustworthy information linked with online technical keyword dictionary. When a user enter a keyword on a portal site, he/she can access to high quality scholarly information resources linked with keyword. This could assure the user to get an expanded knowledge with confirmation.

This study is concerned with selling alliance in the internet shopping services, which is generally used by portal sites in recent and that is a typical form of strategic alliance. This study tried to find the relationship between. consumer's attitude and alliance performance. The authors investigated them in the field. then searched the reasons and determinants of selling alliance performance. As a result of field investigation, the authors found that the traffic of the portal site was not proportionated to the sales of internet shopping mall and this was not consistent with general expectation, With the analysis of it, the authors found that attitudes to the sites (brands) allianced in On-line and recognition of fitting between them had influenced positively on the attitude and purchase intention to alliance services. Moreover, unlike the attitude to the portal sites, the attitude to the internet shopping mall had positively influenced directly on the purchase intention. The other hand. from the view of influence power on the attitude to the allianced shopping service, the recognition of fitting between the sites was the factor which had the least effect of all factors. Compared with Off-line, this is interesting aspect of On-line. So in the On-line selling alliance, be careful of consideration for not only prior attitudes to the partners(portal and shopping mall) but also the fitness between them and make it in the mind that the attitude to shopping mall has greater influence upon the purchase intention than that to portal site.

This study aims to search for education-related datasets provided by public data portals and examine what data types are constructed through classification using topic modeling methods. Regarding the data of the public data portal, 3,072 cases of file data in the education field were collected based on the classification system. Text mining analysis was performed using the LDA-based topic modeling method with stopword processing and data pre-processing for each dataset. Program information and student-supporting notifications were usually provided in the pre-classified dataset for education from the data portal. On the other hand, the characteristics of educational programs and supporting information for the disabled, parents, the elderly, and children through the perspective of lifelong education were generally indicated in the dataset collected by searching for education. The results of data analysis through this study show that providing sufficient educational information through the public data portal would be better to help the students' data science-based decision-making and problem-solving skills.

The ultimate record management's purpose is preservation and utilization. However, the National Archives of Korea (NAK)s Portal has problems such as search system aging and search tools dualization. As a result, the users' search satisfaction is not satisfied, and the improvement demand increases. This study aimed to evaluate the NAK's search quality as a preliminary study for NAK search system advancement. To this end, we analyzed the current status of CAMS and NAK's Portal. Then, we established the test sets and evaluated the NAK's Portal quality from the user's point of view. Evaluation results were analyzed using Precision, Recall, F-score, and MRR. The analysis results showed that the overall search performance was low, particularly in the "advanced subject search," which showed low performance in Precision, Recall, and MRR. Thus, improvement is urgently needed. The test sets established for this study are expected to be used as a basis for objectively measuring the improvement of the search performance after the NAK search system advancement.

This paper describes an approach to building and evaluating a sentiment dictionary using a Web corpus in the game domain. To build a sentiment dictionary, we collected vocabulary based on game-related web documents from a domestic portal site, using the Twitter Korean Processor. From the collected vocabulary, we selected the words whose POS are tagged as either verbs or adjectives, and assigned sentiment score for each selected word. To evaluate the constructed sentiment dictionary, we calculated F1 score with precision and recall, using Korean-SWN that is based on English Senti-word Net(SWN). The evaluation results show that average F1 scores are 0.85 for adjectives and 0.77 for verbs, respectively.

Despite of correlation between climate changes and food-related information, it is still not easy for many users to get access to the information with interest. This study investigated how much climate change and food-related information are correlated with each other and how often they are exposed through frequency and correlation analysis on news articles on the internet portals. Through analysis on the frequency of climate change and food-related news articles, this study was able to figure out how often they are exposed at the same time by the internet news portals. In addition, a total of 59 correlation rules regarding the climate change and food-related vocabularies were derived from these news articles using the climate change and food-related glossaries. Then, a correlation between certain climate change-related and food-related words was analyzed in order to package the related words.
