Abstract
The intelligent retrieval method of information resources is the key technology of literature information search in digital library. The detection results directly determine the performance of subsequent literature information search. Therefore, an intelligent retrieval algorithm for literature information resources in digital library is designed. Firstly, the Gaussian smoothing filter and the wavelet are used to process the literature information resources in digital library to hide the useless information, and construct a new literature information resource signal in digital library. Secondly, the information is divided into the target information and the database information through the threshold. The iterative method is used to retrieve the optimal threshold of digital literature information, and the structural elements of literature information resources in digital library under two different scales are weighted and combined to obtain the final literature information resources and intelligently detected. Finally, the simulation results show that the designed algorithm can accurately extract the literature information resources in digital library, and has a wide range of practicability and application value.
