In this paper, we compare e-book category based on Classification of disciplines with the one based on Chinese Library Classification (ZTF), and propose a novel method to define new knowledge element structure by using the concepts involving knowledge element and the rich semantic information derived from Chinese Wikipedia concept database. We compute the semantic similarity and semantic associativity between the extracted book concepts and the discipline categories, followed by linking the book to the category with semantic information. In the end, the proposed system of discipline indexing of digital library is presented.
