Construction of Library Information Retrieval System Based on Data Mining

To solve the problem of low recall in traditional fast information retrieval methods, this paper proposes a fast retrieval method of massive library information based on data mining technology and supported by distributed open source framework Hadoop. According to the requirements of library resources retrieval, the system framework is designed, and the retrieval algorithm is compiled by using data mining technology. Then, under the system architecture, the implementation process of the system and the retrieval mechanism of library resources in the distributed environment are determined. The performance of the system is tested by multiple sets of experimental data. Compared with other similar retrieval systems, the retrieval efficiency of the designed system has been significantly improved, and with the increase of data volume, the improvement efficiency will be more obvious.
