Abstract: Aiming at the problems of inaccurate retrieval results and low efficiency of the traditional self-integrated information retrieval method in the retrieval of the selfintegrated information of books, we proposed a fast retrieval method for selfintegrated information of books based on Top-k query algorithm. Firstly, the Top-k query algorithm was used to match the denoising selfintegrated information. Secondly, a fast retrieval model of selfintegrated information was established to quickly retrieve the selfintegrated information of books according to the importance of word meaning. The simulation results show that the proposed method has good retrieval performance, the overall operation time is shortened, the retrieval efficiency is improved, and the retrieval results are more accurate.
