Recently, much attention has been paid to manage amount of personal contents effectively. Private photo is one of the most important types of personal contents. In many of conventional approaches for private photo searching, a user is required to assign annotations manually to the private photos of the user by oneself. However, assigning annotations is tedious for a user. This paper introduces an automatic indexing approach for private photo searching based on e-mail message archive. Many of e-mail messages of a user may describe some experiences of the user. In this approach, the temporal expressions are extracted from an e-mail message, and they are used for estimate the relativity between a term in the e-mail message and a temporal interval in the personal time space of a user. The weight of a term to a private photo is calculated on the basis of the relativity and the granularity of the temporal interval.
