ABSTRACT

In this chapter, we present the system called Takealook, which personalizes information presentation according to the user’s interests and knowledge. The incorporation of this system into the POC will allow general informa­ tion or ideas to be personalized for each individual person. A user will be able to easily find out about or access information s/he did not know about or was not previously interested in due to a lack of knowledge. The system infers the user’s interests from her/his question-and-answer interac­ tions and the information presenters’ conceptual spaces by using the related method of collaborative filtering. It then provides additional information about current contents and also recommends other related contents. The user’s interests are represented by her/his own individual conceptual space (i.e., a set of related keywords) which is adapted to her/his preferences. In this chapter we describe a method for personalizing the information presentation, implementating the system at reviewing an exhibition, and experimental results. In the experiment, three user types were observed in the normal system and comparable random modes. It was found that the system not only adapted to the user’s known and unknown interests but also aroused her/his curiosity.
