Patent retrieval analysis method and system and storage medium

Abstract

The invention discloses a patent retrieval analysis method and system and a storage medium. The patent retrieval analysis method comprises the steps: S101, obtaining text data input by a user; S102, judging the type of the text data; S103, when the text data is keywords, entering the step S106; S104, when the text data is paragraph characters, converting the paragraph characters into a plurality of to-be-selected character groups, and outputting the converted to-be-selected character groups to a user interface for the user to select; S105, obtaining a to-be-selected character group selected bythe user according to an operation instruction of the user to obtain keywords, and entering step S106; S106, generating a plurality of retrieval expressions according to the keywords; and S107, inputting each retrieval type into a database to obtain related retrieval results, summarizing all the retrieval results, and outputting the summarized retrieval results. According to the patent retrievalanalysis method and system and the storage medium, the retrieval result can be rapidly obtained for further screening or use of the user, and the retrieval efficiency of the user can be improved, andthe patent retrieval difficulty is reduced, and the omission rate is low.

Description

technical field [0001] The invention relates to the technical field of data retrieval, in particular to a patent retrieval and analysis method, system and storage medium. Background technique [0002] There are many existing patent databases, and practitioners in the patent field need to search for the required patents in the patent database based on various needs. Due to the large amount of patent data in the patent database, it is generally difficult to retrieve useful patent data. At present, practitioners in the patent field mainly rely on manual retrieval to obtain patent documents, which is inefficient and has a high omission rate. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a patent retrieval and analysis method, system and storage medium that can assist manual retrieval quickly and have a low omission rate. [0004] Technical solution: In order to achieve the abo...
