  • Information filtering for internet search, in which new information retrieval environment is given, is different from traditional methods such as bibliography information filtering, news-group and E-mail filtering. Therefore, we cannot expect high performance from the traditional information filtering models when they are applied to the new environment. To solve this problem, we inspect the characteristics of the new filtering environment, and propose a semantic-based filtering model which includes a new filtering method using WordNet. For extracting keywords from documents, this model uses the SDCC(Semantic Distance for Common Category) algorithm instead of the TF/IDF method usually used by traditional methods. The world sense ambiguation problem, which is one of causes dropping efficiency of internet search, is solved by this method. The semantic-based filtering model can filter web pages selectively with considering a user level and we show in this paper that it is more convenient for users to search information in internet by the proposed method than by traditional filtering methods.

  • 정보 네트워크의 발달은 단순한 기술 개발의 단계를 넘어서서 경제, 사회, 문화, 교육 둥 모든 분야의 변화를 강제하는 수단으로 자리잡았다. 기존의 지식과 새로운 지식은 서로 공존하고 충돌하는 과정에서 발전하고 쇠퇴하였으며, 그 변화의 빠르기는 예측이 불가능한 상태로까지 치닫고 있다. 단순한 정보 전달의 방식으로부터 이해와 설득까지도 포함하는 인터랙티브한 커뮤니케이션 방식으로의 전환은, 정보를 합목적적으로 가공하고 편집하는 정보 디자인의 영역을 커뮤니케이션 흐름의 전면에 부각시키는 결과로 연결되었다 미래를 지향하고 새로운 정보 네트워크 환경을 수용하는 새로운 디자인의 개념확립과, 이를 적극적으로 디자인 교육과정에 접목시킬 수 있는 교육 프로그램의 개발은, 디자인 지식노동자로서의 디자이너를 양성하고 디자인 교육 인프라를 구축하는데 선행되어야할 매우 중요한 과제라 하겠다. 본 논문에서는 새로운 디자인 교육 프로그램을 위한 과정으로서, 정보 네트워크 사회로의 변화에 따른 새로운 디자인 패러다임의 변화와, 변화에 적응하기 위한 요건으로서의 디자인교육 프로그램의 과제, 그리고 이러한 조건을 만족시키기 위한 새로운 교육 프로그램을 연구하였다.

  • This study examines female new seniors' clothing consumption behaviors, such as their information sources, clothing store selection criteria, and perceived importance of sales associates' attributes, based on their level of clothing involvement. A face-to-face survey was conducted through a market research firm. The subjects of this study were female adults in their 50s and 60s residing in the Seoul metro area (N=197). Significant differences were found in the clothing consuming behaviors of new seniors depending on their clothing involvement(CI). High-CI new seniors tended to place more importance on both personal and non-personal information sources than low-CI new seniors. High-CI new seniors place importance both "merchandise assortment and store atmosphere" and "sales associates and service" when they select stores for clothing than low-CI new seniors. In terms of sales associates' attributes, high-CI new seniors tend to place more importance on customer-orientation than medium- and low-CI groups. Medium- and high-CI new seniors tend to place more importance on appearance than low-CI groups. However, there were no significant statistical differences for professional expertise among the three different CI groups.

  • Gestures have been employed for human computer interaction to build more natural interface in new computational environments. In this paper, we describe our approach to develop a gesture interface using spatial context information. The proposed gesture interface recognizes a system action (e.g. commands) by integrating gesture information with spatial context information within a probabilistic framework. Two ontologies of spatial contexts are introduced based on the spatial information of gestures: gesture volume and gesture target. Prototype applications are developed using a smart environment scenario that a user can interact with digital information embedded to physical objects using gestures.

  • 인터넷 GIS란 인터넷에 GIS기법을 접목하여, 인터넷 환경에서 GIS서비스가 가능하도록 인터넷 상에서 구축된GIS를 말한다.인터넷 GIS는 동적 클라이언트/서버 컴퓨팅 환경에서 웹을 통해 공간 데이터에 대한 검색 및 분석을 가능케 한다. 본 논문에서는 강남구를 사례로 GIS를 이용한 새주소관리시스템 및 인터넷 GIS를 이용한 새주소 안내시스템 개발 사례를 소개한다. 새주소란 우리나라의 지번을 토대로 한 현행 주소체계가 갖고 있는 문제점을 보완하기 위해 도로방식에 의해 주소를 새로이 부여하는 것으로서 도로를 중심으로 도로명과 건물번호를 체계적으로 부여하는 제도이다. 새주소 관리시스템이란 도로의 신설, 건물의 신축, 소멸등에 따른 주소의 변화를 관리하기 위해 GIS를 이용하여 개발한 시스템이다. 새주소 안내시스템이란 새주소 관리시스템을 인터넷 상에서 구축하여 모든 사람에게 지리정보 및 주소에 대한 안내를 제공하는 시스템이다. 새주소 안내시스템은 GIS데이타의 공유와 통합환경에서 GIS구축의 효율성을 증진시키고, 시스템 구축에 따른 파급효과를 극대화할 수 있을 것으로 예견되었다.

  • We introduce a new architecture of hetero-hybridized feed-forward neural networks composed of fuzzy set-based polynomial neural networks (FSPNN) and polynomial neural networks (PM) that are based on a genetically optimized multi-layer perceptron and develop their comprehensive design methodology involving mechanisms of genetic optimization and Information Granulation. The construction of Information Granulation based HFSPNN (IG-HFSPNN) exploits fundamental technologies of Computational Intelligence(Cl), namely fuzzy sets, neural networks, and genetic algorithms(GAs) and Information Granulation. The architecture of the resulting genetically optimized Information Granulation based HFSPNN (namely IG-gHFSPNN) results from a synergistic usage of the hybrid system generated by combining new fuzzy set based polynomial neurons (FPNs)-based Fuzzy Neural Networks(PM) with polynomial neurons (PNs)-based Polynomial Neural Networks(PM). The design of the conventional genetically optimized HFPNN exploits the extended Group Method of Data Handling(GMDH) with some essential parameters of the network being tuned by using Genetie Algorithms throughout the overall development process. However, the new proposed IG-HFSPNN adopts a new method called as Information Granulation to deal with Information Granules which are included in the real system, and a new type of fuzzy polynomial neuron called as fuzzy set based polynomial neuron. The performance of the IG-gHFPNN is quantified through experimentation.

  • The emergence of new technologies and devices brings a new environment in the field of cyber security. It is not easy to predict possible security threats about new environment every time without special criteria. In other words, most malicious codes often reuse malicious code that has occurred in the past, such as bypassing detection from anti-virus or including additional functions. Therefore, we are predicting the security threats that can arise in a new environment based on the history of repeated malicious code. In this paper, we classify and define not only the internal information obtained from malicious code analysis but also the features that occur during infection and attack. We propose a method to predict and manage security threats in new environment by continuously managing and extending.

  • It is needed to evaluate information systems actively which has already developed to improve future performance of the organization and foster the activation of information system. The introduction or development of information system also can bring about a organizational success. To measure exactly the organizational performance of information systems, it is needed to develop a new valuation model for a specific information system from a objective pint of view, as well as to equip a standard methodology using BSC measurement. The information system valuation from a objective point of view is of importance as the basic information for the decision to obtain information system. This paper takes aim at investigating a new information system valuation model and developing a information system valuation system using case-based reasoning for predicting currency value of information system in each organization. A new information system valuation system is developed as a web-enabling base. Using this, users are able to estimate the value of specific information system on a real time efficiently.
