Utilizing episodic context in search of personal information archives (2013)

Abstract An important factor in successful search of personal information archives is the searcher’s memory of the contents of the archive. Recently, increasing attention has been paid to episodic memory or source memory related to finding personal information. Unfortunately, due to the absence of records for episodic context, most existing studies have only been able to explore frequently recalled episodic information without examining the correctness of the recalled details. In this paper, we report our studies which not only further explore the information that people tend to recall when looking for previously encountered items, but also examine the features that are likely to be remembered correctly. This study is based the records of three subjects who have very rare collections of two-year long episodic context data from their daily life experiences. Based on these findings, we have developed a system which aims to enable users to search for a variety of personal information with what they are most likely to correctly recall about it. This system is evaluated with the three subjects and their data collections. The results support our hypothesis that utilising episodic context brings better user experience and effectiveness for searching person information.
