Main Research Theme: Investigation and Construction of Memory in Everyday Life
Main Research Issues: Three Types of Memory (Human Memory, Computer Memory, Societal Memory)
My main research theme is investigation of human memory in everyday life and computational support for human memory. I believe that "association" is the essential mechanism for memory. My approach is based on psychology (cognitive psychology) and computer and information science (artificial Intelligence). Currently, I am focusing on the "construction and visualization of memory."
Subject World: A System for Visualizing OPAC
This research aims to visualize heterogeneous terminology, enabling users to operate them for "Subject Retrieval" in OPAC. We have developed a prototype system called "Subject World" in which the user can browse and operate BSH4 (BSH4 Subject Headings) and NDC9 (Nippon Decimal Classification) index terms, and search by subject headings from Osaka City University's OPAC. The system helps users to (1) retrieve OPAC by showing related terms, (2) reorganize retrieved information by enabling users to operate displayed objects, and (3) understand subject catalogs and classified catalogs in OPAC.
Memory-Organizer: A System for Constructing Externalized-Memory
This research aims to construct "externalized-memory" to support human memory and creative activities. We have developed a prototype system called "Memory-Organizer" that helps users to construct externalized-memory. The system consists of six browsers: a thinking space browser, an overlay web browser, an interest space browser, a map browser, a calendar browser, and a knowledge space browser. The system is a part of "Digital Self" described below.
Understanding Self and Others (Digital Self)
This research aims to help one gain greater understanding of one's self and others. Digital Self is a virtualized self built on computers. It consists of (a) "externalized-memory," which aims to externalize and store and contents of human working memory, (b) "physiological-memory," which aims to store human physiological data, and (c) "internalized-information," which aims to acquire information about the self from external information sources.
Memory and Preference for Songs of Japanese
This research aims to investigate memory and preference for songs of Japanese. Based on some psychological experiments, we prensent a model of recalling songs from a title and a model of error recall in Japanese songs.
