Each similarity item of the pattern and a keyword inputted by a user in relation to this similarity item are stored in a table 122. For all projects of project information storing each similarity item and the keyword inputted in conformation to the similarity item concerned of each project in the table 112, it is determined whether the similarity item and keyword of the project are matched to the similarity item and keyword in the table 122, and when they are matched, the value of the stored weight attached to the similarity item is taken as the score as the matched project to calculate the similarity of the project. <P>COPYRIGHT: (C)2004,JPO |
