| Abstract: | Z39.50 is a standard network protocol of information retrieval,especially used in the field of online bibliographic retrieval.In this paper,firstly,we discuss the technology of online bibliographic retrieval service based on Z39 50 and the problem of the current structure is presented.Secondly,we present a distributed architecture that uses the technology of query routing.Thirdly,the basic technology,such as the buildup of Marc index,fetching of the centroid information and loop control are discussed.The system architecture and technology that is presented in the paper increase the query efficiency of distributed resources in the digital library. |
