In the A4-nizing era, the key to efficient document management exists in how we can make it possible to define common & simple index, which can classify A4 document layout effectively. There may be various possibilities. But the first & common step might start with the definition of variable number group corresponding to the rectangle position & shape in the A4 sheet. (Fig)
The word processing software will have to contain a layout-similarity evaluation algorithm. To find the most similar layout document from the web, in my opinion, its index-code should be contained in the filename. It means that when you save the document file you’ve created, the word processing software automatically assign a calculated variable. If I save as ‘application form-A.doc’, the word processing software automatically saves it as ‘application form-A-F6B7AEF.doc’ .
The hexadecimal value 'F6B7AEF' contain the layout index information. And we only put 'F6B7AEF' into search engines dialog box. We can get the most similar layout document from web.
