Research Base On Query And Reference Of Digital Library

Digital Library is an information resource system based on computer and net technology and will become the management means of the next generation on net. It involves a lot of technologies such as net, multimedia, data warehouse, data mining and copyright protection and so on. In our country, Digital Library is under developing, so it is very important and necessary to build our own Digital Library.This paper introduce a unlimited library base on parpallel kork of lots of computers,which comes up with not only data entry,text classification, information store,query optimization,interactive interface,but also provides a new function that can create appropriately mode of class and data elements according to user's query.In addition, in technology, Our system based on query of structure and contents is superior to others that cannot support query of structure and contents.The important work of this paper is to deal with result of query,auto link of references and resource discovery of digital library.References are the most important components of papers and books on technology,and they reflect what author make use of other's research works that are rather valueable to reaser.However,Digital librarys that exist currently don't deal with static reference list.User has to input the same keyword of reference again when he wants to view reference.so,This paper introduce a algorithm to construct reference hyperlink automatically,which will search link address of reference or net to make user query at easy.What's more, This paper designed a new document rank algorithm which made use of the citations between documents. The most effective algorithm will calaulate a appropriate weight in order to sort a large of query result.In addition,this paper also designed a small Search Engineer for digital library according to reference hperlink.
