To be successful in increasingly competitive Internet marketplace, it is essential to capture customer loyalty. This paper deals with an intelligent agent approach to incorporate customer's sensibility into an one-to-one recommendation service in on-line shopping mall. In this paper the focus of interest is on-line recommendation service algorithm for development of Human Sensibility based web agent system. The recommendation agent system composed of seven services including specialized algorithm. The on-line recommendation service algorithm use human sensibility ergonomics and on-line preference matching technologies to tailor to the customer the suggestion of goods and the description of store catalog. Customizing the system's behavior requires the parallel execution of several tasks during the interaction (e.g., identifying the customer's emotional preference and dynamically generating the pages of the store catalog). Most of the present shopping malls go through the catalog of goods, but the future shopping malls will have the form of intelligent shopping malls by applying the on-line recommendation service algorithm.

In recent years, with the advent of e-Commerce the need for personalized services and one-to-one marketing has been emphasized. To be successful in increasingly competitive Internet marketplace, it is essential to capture customer loyalty. In this paper, we provide an intelligent agent approach to incorporate human sensibility into an one-to-one recommendation service in cyber shopping mall. Our system exploits human sensibility ergonomics and on-line preference matching technologies to tailor to the customer the suggestion of goods and the description of store catalog. Customizing the system`s behavior requires the parallel execution of several tasks during the interaction （e. g., identifying the customer`s emotional preference and dynamically generating the pages of the store catalog）. The recommendation agent system composed of five modules including specialized agents carries on these tasks. By presenting goods that are consistent with user interests as well as user sensibility, the accuracy and satisfaction of the recommendation service may be improved.

Compound logistics is a service aimed to enhance logistics efficiency by supporting that shippers and consigners jointly use logistics facilities. Many of these services have taken place both domestically and internationally, but the joint logistics services for e-commerce have not been spread yet, since the number of the parcels that the consigners transact business is usually small. As one of meaningful ways to improve utilization of compound logistics, we propose a brokerage service for shipper and consigners based on the hybrid recommendation system using very well-known classification and clustering methods. The existing recommendation system has drawn a relatively low satisfaction as it brought about one-to-one matches between consignors and logistics vendors in that such matching constrains choice range of the users to one-to-one matching each other. However, the implemented hybrid recommendation system based brokerage agent service system can provide multiple choice options to mutual users with descending ranks, which is a result of the recommendation considering transaction preferences of the users. In addition, we applied feature selection methods in order to avoid inducing a meaningless large size recommendation model and reduce a simple model. Finally, we implemented the hybrid recommendation system based brokerage agent service system that shippers and consigners can join, which is the system having capability previously described functions such as feature selection and recommendation. As a result, it turns out that the proposed hybrid recommendation based brokerage service system showed the enhanced efficiency with respect to logistics management, compared to the existing one by reporting two round simulation results.

최근에 서비스되기 시작한 디지털 멀티미디어 방송은 다양한 종류의 수많은 컨텐츠를 제공하기 때문에 고객은 때로 자신이 선호하는 컨텐츠를 찾는데 많은 시간을 소비한다. 심지어는 선호 컨텐츠를 찾는 동안 이미 방송이 끝날 수도 있다. 이와 같은 문제를 해결하기 위해서는 고객이 필요로 하는 최소 정보만을 추천하기 위한 방법이 필요하다. 본 논문에서는 고객이 시청한 컨텐츠 선호도 전이 확률을 이용하여 고객이 선호하는 컨텐츠를 미리 예측하여 추천하기 위한 알고리즘과 시스템을 제안한다. 제안하는 시스템은 클라이언트 관리자 에이전트, 모니터링 에이전트, 러닝 에이전트, 그리고 추천 에이전트 모듈로 구성된다. 클라이언트 관리자 에이전트는 다른 모듈과 상호 작용을 하면서 조정자 역할을 한다. 모니터링 에이전트는 컨텐츠에 대한 고객의 선호도를 분석하기 위해 고객이 이용했던 usage history 데이터를 수집하기 위한 에이전트이다. 러닝 에이전트는 고객으로부터 수집된 usage history 데이터를 정제하여 시간 변화에 따른 상태 전이 행렬로 모델링하기 위한 에이전트이다. 추천 에이전트는 고객의 상태 전이 행렬로 구성된 모델링 데이터에 본 논문에서 제안하는 선호도 전이 확률 모델을 이용하여 고객이 바로 다음에 선호하게 될 컨텐츠를 추천하기 위한 에이전트이다. 추천 에이전트 모듈에서 컨텐츠에 대한 고객의 선호도 전이 확률을 이용하는 추천 알고리즘을 제안한다. 제안하는 추천 시스템은 무선 인터넷 표준 플랫폼인 WIPI(Wireless Internet Platform for Interoperability) 플랫폼에서 프로토타입 시스템을 설계, 구현하였으며, 실험결과 제안된 선호도 전이 확률 모델의 추천 정확도가 전형적인 방법에 비해 효과적임을 보인다.

With the advent of ubiquitous computing environments, it has become increasingly important for applications to take full advantage of contextual information, such as the user's location, to offer greater services to the user without any explicit requests. In this paper, we propose context-aware active services based on context-aware middleware for URC systems (CAMUS). The CAMUS is a middleware that provides context-aware applications with a development and execution methodology. Accordingly, the applications based on CAMUS respond in a timely fashion to contextual information. This paper presents the system architecture of CAMUS and illustrates the content recommendation and control service agents with the properties, operations, and tasks for context-aware active services. To evaluate CAMUS, we apply the proposed active services to a TV application domain. We implement and experiment with a TV content recommendation service agent, a control service agent, and TV tasks based on CAMUS. The implemented content recommendation service agent divides the user's preferences into common and specific models to apply other recommendations and applications easily, including the TV content recommendations.

본 논문에서는 운전자의 특성, 도로상황, 경로 추천을 담당하는 에이전트와 같은 동적환경정보(DEI:Dynamic Environment Information)를 반영하여 실시간으로 운전자에게 경로를 추천할 수 있는 시스템을 위해 멀티에이전트에 관한 연구를 수행하였다. DEI는 n개의 멀티 에이전트이며 운전자에게 최적화된 경로를 제공할 수 있는 경로추천시스템에 활용되는 환경변수이다. DEI가 반영되는 경로추천 시스템은 멀티 에이전트 연구의 새로운 연구 분야라 할 수 있겠다. 이를 위하여 멀티에이전트 연구의 대표적 실험 환경인 먹이추적문제를 이용하여 새로운 해법을 찾고자 하였다. 본 논문에서는 기존의 먹이추적 실험은 현실성이 결여된 멀티에이전트 연구였기에 기존의 실험환경과 달리 현실세계와 비슷한 실험환경을 제안을 하며 새로운 전략인 Ant-Q 학습을 적용한 알고리즘과 기존의 방향벡터를 활용한 전략과의 비교를 통해 새로운 환경에서의 성능의 향상을 입증할 수 있었다.

The rapid increase of E-commerce market requires a solution to assist the buyer to find his or her interested items. The intelligent agent model is one of the approaches to help the buyers in purchasing items in outline market. In this paper, the user query processing model in the item recommendation agent is proposed. In the proposed model, the retrieval result is affected by the automatically generated queries from user preference information as well as the queries explicitly given by user. Therefore, the proposed model can provide the customized search results to each user.
