Abstract

Real-time accessibility and agility are required in u-commerce under ubiquitous computing environment. Most of the existing recommendation techniques adopt the method of evaluation based on personal profile, which has been identified with difficulties in accurately analyzing the customers' level of interest and tendencies, as well as the problems of cost, consequently leaving customers unsatisfied. Researches have been conducted to improve the accuracy of information such as the level of interest and tendencies of the customers. However, the problem lies not in the preconstructed database, but in generating new and diverse profiles that are used for the evaluation of the existing data. Also it is difficult to use the unique recommendation method with hierarchy of each customer who has various characteristics in the existing recommendation techniques. Accordingly, this dissertation used the implicit method without onerous question and answer to the users based on the data from purchasing, unlike the other evaluation techniques. We applied FRAT technique which can analyze the tendency of the various personalization and the exact customer.

유비쿼터스 컴퓨팅 환경의 전자상거래에서 실시간성과 추천의 정확도를 높이는 연구가 활발히 진행되고 있다. 대부분의 기존 추천기법들은 프로파일 방식의 문제로 고객의 관심도나 고객성향을 분석하기에는 많은 어려움과 비용의 문제가 있으며 고객은 여전히 만족하지 못하고 있다. 이는 구성되어있는 데이터베이스들의 문제가 아니라 기존 자료를 분석하기 위한 평가 자료인 신규로 프로파일을 생성하거나 다양한 프로파일을 생성하는데 문제가 있다. 또한 기존 추천기법에서는 다양한 특성을 가진 각 사용자 계층별로 차별화된 개인화 추천이 어렵다. 따라서 이 논문에서 기존의 평가 자료 방식과 다르게 구매로 인해 발생되어진 자료를 기반으로 사용자에게 번거로운 질의 응답 과정이 없이 묵시적인 방법을 이용하였다. 다양한 개인화 성향과 정확한 고객성향의 내용 분석이 가능한 FRAT 기법을 적용하였다.
