While sharing information through Internet by Web page or XML, familiar labels of information items will reduce the confusion among users. The advises of the language experts for choosing familiar terms may cost money and time, but an automated Indicator can help a user select right terms without any cost. This paper collects Indicators that can be easily found over Internet and compares the efficiency of them for selecting familiar terms. The collected indicators are the number of words in a term, the frequency used in a related Web sites, and the number of search results in portal sites. The results conclude that the found terms by the frequency matches 76% for women's and 71% for men's, which tells that the frequency can be a reference for selecting familiar terms.

The effective probability-based tile pre-fetching algorithm and the collaborative cache replacement algorithm are able to reduce the response time for user's requests by transferring tiles which will be used in advance and determining tiles which should be removed from the restrictive cache space of a client based on the future access probabilities in Web GISs(Geographical Information Systems). The Web GISs have multi-level abstracted data for the quick response time when zoom-in and zoom-out queries are requested. But, the previous pre-fetching algorithm is applied on only two-dimensional pre-fetching space, and doesn't consider expanded pre-fetching space for multi-level abstracted data in Web GISs. In this thesis, a probability-based pre-fetching algorithm for multi-level abstracted in Web GISs was proposed. This algorithm expanded the previous two-dimensional pre-fetching space into three-dimensional one for pre-fetching tiles of the upper levels or lower levels. Moreover, we evaluated the effect of the proposed pre-fetching algorithm by using a simulation method. Through the experimental results, the response time for user requests was improved 1.8%∼21.6% on the average. Consequently, in Web GISs with multi-level abstracted data, the proposed pre-fetching algorithm and the collaborative cache replacement algorithm can reduce the response time for user requests substantially.

This study examines overall user experience associated with Web search engine use including selection, usage of search features, evaluation. The data were collected through individual interviews with 28 faculty members and graduate students. It was found that users tend to select a search engine based on experience and knowledge of certain features and familiarity with an engine itself more than based on previous experience with search results. The results showed the users had mixed opinions regarding cross language retrieval while they did not believe the usage of operators effect the search results. It appears that users are interested in interface design as well as the accuracy of search results.

The concept of Web 2.0, which means that internet users are producers and also consumers is evolved according to the development of web service technology. In the Web 2.0 space, the enormous amount of web contents are produced using many social web services. Proactive display system supports various types of users's web contents. Unfortunately, private web contents sharing facility is imperfect to date. In this paper, we develop a proactive display application which identifies people, displaying their social contents such as blogs and open cafes through wide display devices or multi-media players in physical spaces. For this, we develop a social contents presentation server where users can register their profiles and information on the social contents to be shared through the developed application. Also, we develop a social contents presentation client that proactively identifies the user in close proximity and displays the user's social contents through an intuitive user interface in physical spaces. In addition, we develop an on-the-spot feedback service which supports posting various types of replies and an on-the-spot scrap service which specifies direct sharing of the contents through the intuitive user interface.

The number of websites in Korea is increasing rapidly as demonstrated by more than 510,000websites registered under the ".kr" domain as of the end of December 2000. In order to effectively copewith the deluge of web information and maintain ready access to useful information on the web,utilization and management of web information through websites that have been evaluated and ratedfavorably is becoming increasingly important. As websites now increasingly provide industry-specificinformation, information managers are now finding it essential to meet their specific information needsthrough separation and ranking of useful information from the rest.However, evaluation of industry-specific information requires industry-specific expertise as well asgeneral website evaluation tools. This paper develops a website evaluation model and attempts to rankindustry-specific websites through case studies of previous website evaluation and consultation withexperts in specific industries. Based on the model developed, this paper selects 100 outstanding websitesin 10 areas of construction industry. The research also hypothesizes that, with appropriate modifications,the rating models used for the construction industry can also be applied to other industries for moreefficient information management.e efficient information management.

With the help of information technology, the web 2.0 gives people the environment where they share informations and a means of expressing ideas. The power of web affects interactive storytelling for Alternate Reality Game (ARG). There are less theoretical approaches and practices about ARG in Korea and to understand ARG into a deeper sense shall contribute to the development of domestic culture and its contents. In order to realize this, first we will explore the general idea about ARG. Second, know its elements in Interactive storytelling and finally, analyze the examples.

소프트웨어 개발 과정에서 개발자 상호간의 의견 교환과 정보 공유는 실제로 프로젝트를 정확히 이해하고 분석하는데 있어 필수적인 요구 사항이다. 이러한 상호 정보 교환은 시스템의 정보, 기능, 행위 등을 쉽게 해주는 모델링을 통해 이루어지는데, 최근 모델링 작업을 쉽게 해주는 CASE 도구들이 많이 제공되고 있다. 하지만 각각의 CASE 도구들은 모델링 정보에 대한 서로 다른 포맷을 사용하고 있고, 플랫폼 종속적인 인터페이스를 제공하기 때문에 분산 환경에서의 정보 교환 및 공유가 불가능하다. 이러한 문제를 다양한 형태의 정보의 표현이 가능하며 정보교환의 새로운 패러다임으로 등장하고 있는 XML(Extensible MarkUp Language)을 이용하여 표준 객체지향 분석/설계 방법론인 UML 모델을 저장하고 활용하는 방안을 제시하고자 한다. 메타언어로서의 XML은 웹 환경의 전송 매체 기능을 가지고 있어 분산 환경에서의 정보 공유를 통한 팀 개발과 재사용이 가능하다.

Today, opinion reviews on the Web are often used as a means of information exchange. As the importance of opinion reviews continues to grow, the number of issues for opinion spam also increases. Even though many research studies on detecting spam reviews have been conducted, some limitations of gold-standard datasets hinder research. Therefore, we introduce a new dataset called "Paraphrased Opinion Spam (POS)" that contains a new type of review spam that imitates truthful reviews. We have noticed that spammers refer to existing truthful reviews to fabricate spam reviews. To create such a seemingly truthful review spam dataset, we asked task participants to paraphrase truthful reviews to create a new deceptive review. The experiment results show that classifying our POS dataset is more difficult than classifying the existing spam datasets since the reviews in our dataset more linguistically look like truthful reviews. Also, training volume has been found to be an important factor for classification model performance.

대부분의 아파트의 경우 관리인들이 직접 세대를 방문하여 필요 정보를 전달하고 의견을 수렴하거나 로비층에 게시판을 활용하는 형태로 입주민에게 생활정보를 제공한다. 이런 구조와 더불어 맞벌이 가정 증가, 주간 시간 아파트 거주 인구의 감소 등으로 효과적인 정보 전달이 잘 이루어지지 않아 관리인들의 중복 방문, 정보 미 전달 가구의 민원 발생 등의 문제 또한 많이 나타나고 있다. 본 논문에서는 이런 문제들을 해결하기 위해 안드로이드 시스템과 GCM, JSP 웹을 활용하여 입주민에게 여러 가지 생활 정보를 SNS로 제공하는 시스템에 대하여 제안한다. 제안된 시스템의 경우 통신회사의 네트워크 타입에 종속되지 않는다. 또한 관리사무소는 별도의 인프라 구축이 필요 없어 중복 방문, 홍보물 제작 등의 비용을 절감할 수 있으며 입주민 또한 스마트폰에 APP을 설치하여 실시간으로 여러 생활 정보를 제공 받을 수 있다.

인터넷 시장이 빠르게 성장함에 따라 사용자들의 참여도가 매우 높아졌다. 인터넷 사용자들은 인터넷 쇼핑의 상품에 관한 의견을 웹 상에 표현하기 시작했고, 실제 소비자이 판단하는 데에 많은 영향을 미치고 있다. 하지만 현재에 들어 그 양이 엄청나게 방대해 졌기 때문에 사용자들이 원하는 정보만을 찾아내는 것은 어려운 일이다. 본 논문에서는 사용들이 작성한 인터넷 쇼핑에서 상품평에 관한 리뷰를 모아 방대한 양에서 오피니언 마이닝 기법을 이용해 유용한 정보를 효율적으로 도출해서 사용자가 원하는 정보를 요약하여 제공하는 방법을 제안한다. 이러한 방법을 통해서 사용자는 상품을 구매하기 전에 좀 더 객관적이고 효율적으로 판단을 내릴 수 있을 것이다.
