Abstract

The invention provides a retrieval method and device. The method is applied to a distributed retrieval platform established on the basis of a plurality of retrieval servers. The method comprises the following steps: receiving retrieval terms sent by a user through a retrieval client; traversing the retrieval terms, and performing adjacent term segmentation on the retrieval terms to generate multiple double-term groups; based on the multiple double-term groups, searching retrieval objects corresponding to the multiple double-term groups in a preset retrieval database, and generating a retrieval object list; and calculating the similarity between the retrieval terms and the retrieval objects in the retrieval object list, and returning multiple retrieval objects with similarity higher than a preset threshold to the retrieval client to serve as retrieval results, and displaying the retrieval objects to the user. By adoption of the retrieval method provided by the invention, the text retrieval accuracy in ancient Chinese can be effectively improved.

Description

Technical field [0001] This application relates to the field of computer communication, and in particular to a retrieval method and device. Background technique [0002] Ancient Chinese text retrieval is a commonly used retrieval method for users nowadays. By entering a certain retrieval term, users can retrieve the ancient Chinese text containing the retrieval term. [0003] However, in practical applications, when the search term entered by the user is incorrect, such as a typo in the search term, it is difficult to accurately find the ancient Chinese text that the user needs. Therefore, how to improve the accuracy of ancient Chinese text retrieval becomes an urgent problem to be solved. Summary of the invention [0004] In view of this, this application provides a retrieval method and device to improve the accuracy of ancient Chinese text retrieval. [0005] Specifically, this application is implemented through the following technical solutions: [0006] According to the first asp...
