Generalization of Vector Elements

In order to reduce the dimension, we use "generalization methods." Generalization is an inductive inference method to find rules from examples. In this paper, "generalization" means degenerating the semantic attributes which have little effect in information retrieval into the upper attribute. The weight of the attributes which are deleted from bases are added to the weight of the upper node.

Here, we consider the following two kinds of generalizations:
