Keyword Automatic Retrieval Method of Library Books and Materials Based on Multimodal Learning
Aiming at the problems of low accuracy and recall rate of existing keyword retrieval methods of library books and materials,a keyword automatic retrieval method of library books and materials based on multimodal learning is designed.Multimodal learning is used to realize the automatic classification of library books and materials.The library books and materials is regarded as the space unit,and the keywords of the library books and materials are extracted.The keyword similarity of the library books and materials is calculated,and the library books and materials whose similarity exceeds the threshold is displayed to the user,and the search results that meet the user's expectation are output.In order to verify the feasibility of the proposed method,comparative experiment is carried out.The results show that the accuracy and recall rate of the search results obtained by the proposed method are relatively high,which can provide users with search results that meet their needs according to the keywords provided by users.
