Research Abstract	Recently, according to the remarkable increasing of the number of personal contents, such as e-mail messages and digital photographs and so on, it is required to develop an effective search technique for personal contents. One of the characteristic features of personal contents is that many of personal contents are related to personal experiences. In this work, we treat personal contents as representations of personal experience, and we assume that a user requests to obtain various types of information about personal experiences instead of personal contents on personal contents search. Based on this assumption, we have developed a novel ranking technique for personal contents. This technique uses explicit links and implicit links among personal contents for ranking. The ranking criterion is how sufficiently targets represent personal experiences.
