Problems solved by technology

However, in the above information retrieval scheme, it is necessary to calculate the similarity between the search terms and each candidate search result. If the number of candidate search results is large (if the number is n), the corresponding computational complexity is O(n)
Therefore, when using the above information retrieval scheme, it is very computationally complex to select the retrieval result that the user really needs from the numerous candidate retrieval results.

Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0039] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is t...

Abstract

The invention relates to an information retrieval method and device, computer equipment and a storage medium. The method comprises the steps of obtaining an input search word; searching at least two candidate retrieval results according to the retrieval word; obtaining semantic related information between the configured retrieval word and the candidate retrieval result; determining a target retrieval result matched with the retrieval word from the candidate retrieval results according to the semantic related information; and outputting the target retrieval result so as to display the target retrieval result on a retrieval page of the social application. By adopting the method, the calculation complexity in the information retrieval process can be reduced.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to an information retrieval method, device, computer equipment and storage medium. Background technique [0002] For information retrieval, it is usually to use the search term to conduct a rough search first, find all the content that has a certain relationship with the search term as candidate search results, and then calculate the similarity between the search term and each candidate search result. The candidate retrieval results are sorted and then output. However, in the above information retrieval scheme, it is necessary to calculate the similarity between the search terms and each candidate search result. If the number of candidate search results is large (if the number is n), the corresponding calculation complexity is O(n). Therefore, when the above information retrieval scheme is adopted, the computational complexity of selecting the retrieval re...
