Research on technology of the network dynamic auditing & automatic acquisition of scientific information

This paper gives an overall survey to the Robot based Web information retrieval (IR), focuses information retrieval, intelligent information retrieval and intelligent information agent, and relevant theory, methods and technology of the information automatic acquisition, discusses the information retrieval methods and strategies suitable to the requirements of technology forecasting and accessing, to be used in the inforaion gethering on specific scientific areas, and to the intelligent network information acquisition. And conduct the selection work for the scientific resources which can be use for automatic collection. Based on these discussions, the paper constructs the framework on the dynamic auditing and automatic acquisition system on Internet WWW network scientific technology information, and realizes a prototype of the Web based information system (named BIT), at last, analyses the characteristics of the system.
