Information presentation by inferring user's interests based on individual conceptual spaces

We present the system called Takealook, which personalizes information presentation according to the user’s interests and knowledge. The system infers the user’s interests from her/his question-and-answer interactions 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 paper we describe a method for personalizing the information presentation, implementating the system at reviewing an exhibition, and experimental results. © 2000 Scripta Technica, Syst Comp Jpn, 31(10): 41–55, 2000
