ABSTRACT:
Because the whole image of a retrieved document group cannot be viewed, next retrieval request after one retrieval attempt has been determined only perceptually. Therefore, displaying a means for displaying topic words on a display means, extracting a group of words characteristically appearing in a retrieved document group on request from a user, further examining the relation between topic words, and preparing a graph using the topic words as nodes, the whole image of the retrieval results is displayed on the means for displaying topic words. Additionally, by selecting an interesting word or a word with no interest on a displayed graph of topic words, the user can design a subsequent retrieval strategy effectively.
