document: An integrated method for social network extraction A social network can become bases for information infrastructure in the future . It is important to extract social networks that are not biased . Providing a simple means for users to register their social relation is also important . We propose a method that combines various approaches to extract social networks . Especially , three kinds of networks are extracted ; user-registered Know link network , Web-mined Web link network , and face-to-face Touch link network . In this paper , the combination of social network extraction for communities is described , and the analysis on the extracted social networks is shown .
