Book Recommendation (Keita Tsuji) Lab
Machine-translated · View original
A library and information science lab that uses data to study book recommendation and library management.

AboutAbout the lab
Understanding library books and operations through data.
The Book Recommendation (Keita Tsuji) Lab studies what books are held in public and university libraries and how they are used.
The lab has also studied a system that recommends university library books based on the Wikipedia article a user is reading.
It has also investigated how the designated manager system, in which the operation of public libraries is entrusted to private companies and other organizations, affects library use.
Currently, the lab is working on building a model in which public libraries and kodomo shokudo (community cafeterias for children) provide books to children from families living in poverty.
