Abstract
Parents need to select the picture books for their children, until they can read them by themselves. However, it is difficult for them to find the picture books that are suitable for their children among a number of published books. To resolve such problems, we developed Picbok, a social picture book recommender system that uses children's questions because their preferences are revealed in their questions. On our system, children's questions are recorded by their parents, and are shared by all the other users. Users can recommend picture books to each other. In order to evaluate the effectiveness of our system, we conducted an experiment with 25 pairs of parents and their children.
