Takealook: personalizing information presentation according to user´s interest space

In this paper, we present a system called Takealook, which personalizes information presentation according to individual interests and knowledge of the user. The basic idea is that the system infers a user´s interests and personalizes information presentation by processing the user´s operation history and the interest space. The user´s interest space is structured from the presenter´s individual conceptual space and the user´s operation history, which is acquired through question-answer interactions between the user and the system. We employ a method similar to collaborative filtering for improving interest spaces
