In this paper, we propose a new customer profile model based on customer behavior in Internet shopping mall. The proposed technique defines customer profile model based on customer behavior information such as click data, buy data, and interest categories. We also implement CBCPM(Customer Behavior-based Customer Profile Model) and perform extensive experiments. The experimental results show that CBCPM has higher precision, recall, and F1 than the existing customer profile model.

Introducing the market into the electricity industry lets the multiple participants get into new competition. These multiple participants of the market need new business strategies for providing value added services to customer. Therefore they need the accurate customer information about the electricity demand. Demand characteristic is the most important one for analyzing customer information. In this study load profile data, which can be collected through the Automatic Meter Reading System, are analyzed for getting demand patterns of customer. The load profile data include electricity demand in 15 minutes interval. An algorithm for clustering similar demand patterns is developed using the load profile data. As results of classification, customers are separated into several groups. And the representative curves for the groups are generated. The number of groups is automatically generated. And it depends on the threshold value for distance to separate groups. The demand characteristics of the groups are discussed. Also, the compositions of demand contracts and standard industrial classification in each group are presented. It is expected that the classified curves will be used for tariff design, load forecasting, load management and so on. Also it will be a good infrastructure for making a value added service related to electricity.

To analyze the load of distribution line, real LPs (Load Profile) of AMR (Automatic Meter Reading) customers and VLPs (Virtual Load Profile) of non-AMR customers are required. Accuracy of VLP is an important factor to improve the analysis performance. There are 2 kinds of methods to generate the VLP; one is using ALP (Average Load Profile) per each industrial code and PNN (Probability neural networks) algorithm; the other is using LSI (Load Shape Index) and C5.0 algorithm. In this paper, existing researches are studied, and new method is suggested. Each methods are compared the performance with same LP data of real high voltage customers.

Recently, distribution load analysis using AMR (Automatic Meter Reading) data is researched in electric utilities. Load analysis method based on AMR system generates the typical load profile using load data of AMR customers, estimates the load profile of non-AMR customers, and analyzes the peak load and load profile of the distribution circuits and sectors per every 15 minutes/hour/day/week/month. Typical load profile is generated by the algorithm calculating the average amount of power consumption of each groups having similar load patterns. Traditional customer clustering mechanism uses only contract type code as a key. This mechanism has low accuracy because many customers having same contract code have different load patterns. In this research, We propose a customer clustring mechanism using k-means algorithm with contract type code and AMR data.

Customer clustering method is used to make a TDLP (typical daily load profile) to estimate the quater hourly load profile of non-AMR (Automatic Meter Reading) customer. In this paper, repeated small-sized clustering method is supposed to improve the classifying ability of TDLP. K-means algorithm is well-known clustering technology of data mining. To reduce the local maxima of k-means algorithm, proposed method clusters average load profiles to small-sized clusters and selects the highest error rated cluster and clusters this to small-sized clusters repeatedly to minimize the local maxima.

Although food related lifestyle has been widely discussed over the last ten years, the majority of research on food related lifestyle has been only conducted in terms of a variable-centered approach. But, recently there is a growing body of research on food related lifestyle profiles over the last three years from the view of a person-centered approach. This study conducted both a cluster analysis and a latent profile analysis (LPA) to identify the patterns of potential food related lifestyle customer profiles based on the five components on the sample of customer, who bought organic products (n=509). The results of each statistical analysis showed both quantitatively and qualitatively different types of food related lifestyle customer profiles even though there were similar types of profiles identified in common between these two analyses. These various profiles were then compared with customer's level of buying behaviors (e.g., buying attitude and buying intentions). Results showed that food related lifestyle profiles with respect to the high level of interesting in dietary life in terms of health and safety are associated with the higher level of buying behaviors. Based on the results, implications for food related lifestyle literature, practices and future research are discussed.

일대일 마케팅을 실현하고 정보 과다 문제의 해결책으로 등장한 추천시스템의 다양한 기법을 적용하기 위해서는 고객의 관심 분야에 대한 정보인 고객 프로파일의 정의가 선행되어야 할 것으로 판단된다. 본 연구에서는 고객에게 개인화된 정보를 추천하기 위해 고객 개인의 행동과 그 고객이 속한 그룹의 행동 정보에 기반한 고객 프로파일 모델인 IGBCPM(Individual Group Behavior Customer Profile Model)을 제시한다.

전자상거래 시스템의 보급이 활성화되기 시작하면서 사용자의 구매 행위에 적응형으로 대처하는 지능형 전자상거래 에이전트의 필요성이 증대되고 있다. 이와 같은 적응형 전자상거래 에이전트는 사용자의 구매 행위를 모니터하면서, 각 분야별 고객의 구매 행위를 자동 분류하고, 분류된 각 클러스터로부터 사용자의 취향을 학습하는 하는 기능을 필요로 한다. 이러한 기능을 가지는 적응형 전자상거래 에이전트를 구축하기 위해서 본 논문에서는다음 3가지 부분에 중점을 두고 시스템을 설계하였다. 첫째, 사용자의 구매 행위를 포괄적으로 모니터하여 사용자 행위로 추상화하는 모니터 에이전트, 둘째, 고객 구매 행위 데이터로부터 유사한 분야 구매 데이터들로 클러스터 하는 개념적 클러스터 에이전트, 셋째, 각 클러스터로부터 사용자 프로파일을 구축하는 사용자 프로파일 에이전트를 중심으로 설계하는 방안을 제안하고 있다 특히, 본 논문에서는 보다 정확한 고객 구매 행위를 학습하기 위해서 개념적 클러스터링 방식과 귀납적 기계학습 방식을 적용하는 2단계 구조를 제안하고 있다.이와 같은 구조는 여러 분야의 상품을 구매한 정보로부터 사용자의 다중 취향을 학습할 때발생하는 문제를 해결함으로, 사용자 프로파일을 정확하게 구축할 수 있는 장점이 있다. 이러한 정확한 사용자 프로파일을 기반으로 사용자에게 보다 적절한 정보를 제공하는 적응형 전자상거래 시스템을 만들 수 있다.

인터넷에서 고객들에 의해 생성된 평가정보는 해당 상품에 대한 고객별 선호도 정보로도 간주할 수 있기 때문에 개인화 추천을 위한 고객 프로필 생성에 효과적으로 활용될 수 있다. 하지만, 온라인에서의 상품평가는 누구나 작성할 수 있고, 왜곡된 목적으로 가지고 평가 행위를 하는 경우도 많아 평가정보의 신뢰도 편차가 크다. 따라서 본 연구에서는 상품에 부여된 평가정보 자체의 신뢰도를 측정하고 이를 추천시스템의 고객 프로필 생성 과정에 선별적으로 반영하는 방법론을 제안하고자 한다. 몇몇 추천 시스템 관련 연구에서 평가정보 작성자 수준에서 신뢰도를 측정하고 이를 활용하려 했던 것과 달리 본 연구에서는 개별 평가 정보 수준에서 신뢰도를 측정한다. 실험 결과 신뢰도가 일정수준 이상의 신뢰도를 갖는 평가정보만을 선별하여 고객 프로필을 생성할 경우 추천 시스템의 선호도 예측 정확도가 향상되는 것으로 나타났다.

Although researchers have, during the past decade, become increasingly interested in customer satisfaction customer reaction, and service quality issues, very little of research has devoted to the family restaurant. Family restaurant industry is among the fastest growing sectors of the tourism market. This paper discusses the importance of the family restaurant product and service quality, and presents the relationship among service quality, customer satisfaction, and customer reaction. The literature supports the value of family restaurant's service quality and relation between service quality and customer reaction. Exploratory study examined customer's satisfaction with service quality components and customer's reaction with satisfaction. The survey was conducted in four phases; service quality, customer reaction(satisfaction, repurchase intention, and word of mouth), restaurant information, general profile of customer. The results of the study show that service quality(product's quality, physical character) provided family restaurant customer with the overall satisfaction, and service quality affected on customer reaction(repurchase intention, positive word of mouth). Also overall satisfaction affected on repurchase intention and positive word of mouth.
