| Abstract: | The background analysis and concept evaluation for the establishment of the distributed AISS (Astronautics Information Service System)are presented on the basis of the comparision between three kinds of information retrieval systems (IRS): the centralized ,the distributed and the decentralized ones. There are five important factors being considered for the system design of distributed AISS. They are the present organization system of the astronautics information services, the network environment, the user's geographical distribution, the information capacity (size of database) and the financial support. A brief introduction to the AISSnetwork is deseribed as well.The trial experiments of the AISS have shown many excellent performances of the distributed network. |
