Research on Library Information Visualization Retrieval Technology Based on Readers' Needs

Abstract

With the advancement of social informatization and the widespread application of network, the resources accumulated by libraries are becoming larger and larger. In addition to the need to store, transmit, retrieve and classify massive data, there is an urgent need to understand the relationship between data and its development trend. With the continuous development of modern information technology, digital libraries have also made great progress. And to introduce visual information retrieval technology into digital libraries is an inevitable trend in the future development. This paper first analyses the characteristics of readers' information retrieval needs in the new period, and then introduce library information visual presentation technologies to design the library information resource visualization retrieval system. The system can visually display the collection structure, popular books, readers' interests and so on, to truly reflect the structure, coverage, utilization and other indicators of books resource, and provide convenience for the visual sharing of library information resources.
