Abstract:
1. A document processing method, comprising: a collection step of collecting access history of a user; a document similarity computing step of computing a document similarity, which indicates similarity between documents, by one user pattern which indicates a plurality of users who have accessed one document and another user pattern which indicates a plurality of users who have accessed another document, according to the access history collected in the collection step; a keyword weight vector correction step of correcting a keyword weight vector of the one document using the document similarity computed in the document similarity computing step, said keyword weight vector correction step including correcting a keyword weight vector in the other document using the document similarity and correcting a keyword weight vector in the one document using the corrected keyword weight vector; an evaluation value calculation step of calculating an evaluation value for input information for searching, based on the keyword weight vector corrected in the keyword weight vector correction step; a user similarity computing step of computing user similarity, which indicates similarity between users, by one document pattern which indicates a plurality of documents accessed by one user and another document pattern which indicates a plurality of documents accessed by another user, according to the access history collected in the collection step; and a user profile correction step of correcting a user profile which indicates characteristics of the one user using the user similarity computed in the user similarity computing step, wherein the evaluation value calculation step further comprises a step of calculating the evaluation value for the input information for searching based on the user profile of the one user corrected in the user profile correction step.
