Abstract (in Japanese) (See Japanese page) 
(in English) Behavior targeting advertisement is an effective approach to be increasing EC site business. To correspond user’s short-term interest changes, An access log devided to a few access log clusters, then a user’s interest
profiles are made by them. Therefore, the keyword extraction method that explain user is interested in from few access logs are needed. The interest that occuring purchase action often explain as brand words, category words and related words. The co-occuring with these word approach is effective. However, this approach must apply to enough bag of words(BOW). Then this approach can not extract keywords from fewer access logs.
To overcome this problem, we propose the keyword extraction method for fewer access logs. Our proposed approach use co-occuring value with brand and category word from all time access logs, and bias of keyword frequency between target of access log cluster and other access logs.
