  • This paper starts from one question: what are the key factors of the web accessibility policy, which is significant for realizing equity in the web and enhancing human dignity in the information society. To find significant factors for complying with web accessibility, this paper analyzes panel data of 16 Korean local governments (for five years: 2004-2009) according to the research design which is based on the demand and supply balance model and consists of four variables : 'legal and institutional environment (including legal infrastructure)', 'financial foundation (fiscal self-reliance ratio)', 'policy inputs (amount of imformatization budget, employee of information experts)'and 'policy demand (internet usage rate, the number of disabled people and elderly people)'. From the results of this study, this paper can explain the mechanism and impact factors on the web accessibility policy of Korean local governments. Some factors are critical to improve web accessibility: (1) the importance of policy demand, (2) the importance of policy inputs, (3) the importance of legal and institutional environment. Finally, this paper concludes with some suggestions to enhance the web accessibility capacity for Korean local governments: (1) improve awareness on web accessibility, (2) develop a standard and invest R&D on web accessibility, (3) foster experts in web accessibility.

  • In this study, an analytical CRM for customer segmentation is exercised by integrating and analyzing the customer profile data and the access data to a particular web site. We believe that effective customer segmentation will be possible with a basis of the understanding of customer characteristics as well as behavior on the web. One of the critical tasks in the web data-mining is concerned with both 'how to collect the data from the web in an efficient manner?' and 'how to integrate the data(mostly in a variety of types) effectively for the analysis?' This study proposes a panel approach as an efficient data collection method in the web. For the customer data analysis, OLAF and a tree-structured algorithm are applied in this study. The results of the analysis with both techniques are compared, confirming the previous work which the two techniques are inter-complementary.

  • This study explores whether a NBD type of model can be applied to characterize the underlying frequency distribution of online consumer's visit behavior. In this study, the following two research questions are addressed: (1) How can we characterize the underlying distribution pattern(s) of the number of repeat i i visits to a site? (2) How can consumer's Internet usages and his/her demographics affect the average number of visits to the site? Through the empirical investigation, this study found that NBD models are directly applicable to characterize the underlying distribution of visit frequency on the Internet. Furthermore, this study addresses some managerial implications for understanding how site visits are determined. Especially this study highlights the relationship between repeated visits and the visitors' Internet Usages and demographics. The proposed models are estimated and validated by online panel data that covers more than 1000 different sites and has 800,000 observations.

  • 초기에 하나의 상품 카테고리만을 다루던 전자상거래 사이트들이 브랜드 확립 후에 다른 상품 카테고리까지 확대해 나가는 모습을 많이 보아왔다. 고객이 아직 방문하지 않은 신규 상품 카테고리의 상품에 대하여 기존 상품 카테고리에서 만들어진 사용자 프로파일을 활용하여 개인화된 추천을 할 수 있다면, 고객이 다양한 상품 카테고리를 방문하도록 유도할 수 있을 것이다. 하지만 일반적으로 전자상거래 사이트에서는 상품 카테고리별로 사용자의 선호도를 파악하여 개인화된 추천을 수행하기 때문에, 해당 카테고리 내 상품의 구매나 방문 기록이 없다면 개인화된 추천을 수행하기가 어렵다 . 본 논문에서는 협업 필터링을 통해 신규 상품카테고리 내의 상품을 추천하기 어려운 고객들을 대상으로 기존의 사용자 선호도 데이터를 활용하여 신규 상품 카테고리 내의 상품을 추천하는 방안의 타당성을 살펴보도록 한다. 즉, 기존 사용자의 특정상품 카테고리 선호도 데이터를 통해 사용자간 유산도를 계산하고, 이를 추천하려는 타 상품 카테고리 내의 상품들에 대한 예측 선호도 계산에 활용 타당성을 살펴본다. 이를 실증적으로 검토하기 위해서, Yes24 사이트의 서적, 음반, DVD 3개의카테고리 내의 상품을 방문한 웹 패널 데이터를 이용하여 타당성 분석을 수행하였다. 분석 결과, 동일 상품 카테고리 내의 선호도 정보를 가지고 현업 필터링을 수행하는 것보다는 추천 성과가 낮았지만 활용할만한 추천 성과를 보였으며, 활용하는 상품 카테고리와 예측하는 상품 카테고리별로 추천성과가 상이했다.

  • Many users visit websites every day to perform information retrieval, shopping, and community activities. On the other hand, there is intense competition among sites which attempt to profit from the Internet users. Thus, the owners or marketing officers of each site try to design a variety of marketing strategies including cooperation with other sites. Through such cooperation, a site can share customers' information, mileage points, and hyperlinks with other sites. To create effective cooperation, it is crucial to choose an appropriate partner site that may have many potential customers. Unfortunately, it is exceedingly difficult to identify such an appropriate partner among the vast number of sites. In this paper, therefore, we devise a new methodology for recommending appropriate partner sites to each site. For this purpose, we perform site clustering from the perspective of visitors' similarities, and then identify a group of sites that has a number of common customers. We then analyze the potential for the practical use of the proposed methodology through its application to approximately 140 million actual site browsing histories.
