With daily enterprise activity, the activity has been electronically accumulated in the form of documents including a newspaper. By retrieving the documents about an attention enterprise, it is the environment which can get to know the enterprise. However, actually it is difficult to grasp the enterprise activity due to the huge amount of documents. It is the situation that an enterprise evaluation such as growth characteristics can not help relying on the fragmentary memory of each analyst. We propose a quantification method of enterprise characteristics using documents in this paper. This proposed method enable to give the degree of arbitrary characteristics concerned to the enterprise quantitatively, and then an comprehensive enterprise evaluation is promoted. In addition, this method realizes extraction of documents revevant to each characteristic by a common principle. By this method, a document is expressed by a vector based on included terms and an object of an enterprise and its characteristic is generated through a vector set corresponding to the documents in a form of subspace. The degree of relations between them is quantified by an angle of the two subspace. The effectiveness of the proposed method was shown through experimental results using newspaper for the case of an enterprise's intellectual potential.
