The discussion focuses on the following three information processing technologies. 1.information extraction. 2.deductive inference. 3.data mining. The most significant applications are discovery and derivation of new information and knowledge. This paper discusses how these information processing technologies can be exploited to complement the capabilities of human beings in the digital library domain. the tasks that the developed information processing utilities perform are simple and tedious intelligent information processing. However, because a digital library contains a large quantity of contents, it is common that human beings can hardly carry out such tasks exhaustively. As a result, a great amount of information and knowledge may remain undiscovered without the assistance of assistance of such utilities. On the other hands, with the developed information processing utilities, human being are the released from performing tedious work and can spend more time with more hilosophical activities to derive advanced knowledge.Information processing technologiesDigital libraryInformation extractionDeductive inferenceData mining
