We report the progress of our research on “constructing externalized-memory,” conducted since 2013. We have focused on systems to support personal memory recall using an information structure called history structure. Before 2013, we developed a system called knowledge-space browser, which displays a network called “knowledge-space” from various information activities. Since 2013, we have been developing a system, called tag browser, that displays a tag cloud based on the usage of Calendar and Twitter, as well as continuing our development of the knowledge-space browser. The main feature of our current research is to use the number of photos to weight a system’s keywords. In this paper, we (a) describe the tag browser and (b) compare the tag cloud and the network as approaches to support human memory recollection.
