Abstract

The invention relates to a semantic analysis technology, and discloses a retrieval method based on keyword prompt, which comprises the following steps of: obtaining an input word of a user, and carrying out similar character matching on the input word to obtain a similar character set; carrying out error prompting on the input word by utilizing a similar character set to obtain a search word; monitoring a user instruction of a user, and when the user instruction is a retrieval instruction, performing retrieval by utilizing the retrieval word; when the user instruction is an input instruction, performing associated word matching on the search words to obtain an associated word set; performing topic screening on the associated word set to obtain a topic word set with the same topic as the search word; and prompting the user by utilizing the subject word set to obtain a retrieval word group, and retrieving by utilizing the retrieval word group. In addition, the invention also relates to a blockchain technology, and the associated words can be stored in nodes of the blockchain. The invention furthermore provides a retrieval device based on keyword prompt, equipment and a storage medium. According to the method and device, the problem of low efficiency and accuracy during keyword-based retrieval can be solved.

Description

technical field [0001] The present invention relates to the technical field of semantic analysis, in particular to a keyword prompt-based retrieval method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Data retrieval is a function that people attach great importance to when dealing with work and study in their daily life. There is a large amount of data in the Internet, and how to accurately and efficiently query the data that users need has become the focus of people's attention. [0003] Most of the existing methods to improve the accuracy and efficiency of data retrieval are the prefix matching method based on Tire tree. This method uses the words input by the user to match the key words from the preset keyword database to realize the search prompt for the user and assist the user to complete the search. However, in this method, the requirements for word matching are too high. When there are typos in words, etc., it is im...
