Design And Implementation Of Book Knowledge Service System Based On Knowledge Organization

There are lots of knowledge in the traditional book, but there is no way to search them quickly and accurately. So we need a solution to fragment the traditional book and re-construction them. More than 2.6 million books in digital library CADAL provide us the data source. And that we extract the rich knowledge from the books will enhance our reading and knowledge service.So, we are hoping to extract the knowledge units in digital books, and reconstruct knowledge units to ease user. In this paper, we propose a structural learning method to build a big and complex hierarchical structure from fragments. And we extend this structure though topological analysis and knowledge unit. At last, we apply this complex structure to book knowledge service.The paper regard the actual project as the background. We develop and test the China Knowledge Centre for Engineering Sciences and Books Knowledge service. The main work includes 1) Researching the related work about the structural learning and annotation.2) Based on affinity propagation, we propose a structural learning method and we construct the hierarchical structure from the catalog in books based on this method.3) We proposed a method based on Word2Vec+AP_Cluster+TextRank to label the picture and mining the topological structure on the catalog of the books. Then, we extend the hierarchical structure with picture and topological structure.4) Applying hierarchical structure to our service.5) Giving the implementation and test of the entire system. The system is available on the internet.
