| Abstract: | This paper brings forward a method of auto-construction of concept map based on term co-occurrence technique.Firstly,the paper selects the terms and computes the relation strength between terms to form the proximity matrix.Then,the paper mines the concept map from the proximity matrix.Finally,the paper displays the concept map with visualization technique dynamically.Experiments prove that the new mining algorithm and visualization technique can improve the effect of auto-construction of concept map. |
