Topic-sensitive keyword map generation for intelligent interaction
Yasufumi Takama · 2003
An immune network metaphor is proposed to improve the expressive power of a keyword map. As the information environment such as WWW grows, the role of information visualization systems becomes important. Compared with the ordinary keyword map, in which only the distance between keywords is a clue to understand it, the proposed method adds the additional information such as landmark and its related keywords into a keyword map. Experimental results show that the immune network metaphor can obtain the keyword map that emphasizes the topic distribution based on the landmarks, with small variance per execution. The proposed system will be the essential foundation for realizing intelligent interaction between the user and the system.
