Abstract(in English) It is impossible to simply interpret a link on a Webpage as "confidence to the linked page" due to the increase in the amount of information on the Web, and the availability of simple information dispatch tools, such as Weblog. By getting to know the feeling implicitly expressed by the link on the Web, we think that it becomes possible to find more densely cooperated Web Communities. Thus, in this research, we tried to estimate a sentiment polarity score by supervised learning to the link in Weblog. By taking into consideration the deviation of expression between in a positive document and in a negative document, and document structure peculiar to Weblog, we found that about 0.45 can be conjectured with remarkable correlation by Pearson's correlation coefficient.
