Text retrieval method and device, storage medium and electronic device

Abstract

The invention discloses a text retrieval method and a device, a storage medium and an electronic device. The method comprises the following steps: acquiring a first patent text uploaded by a client; obtaining a key text extracted from the first patent text and a patent classification number matched with the first patent text; sending a first retrieval request generated by utilizing the key text and the patent classification number to a server, the first retrieval request being used for requesting retrieval of the first patent text; obtaining a first patent text list which is returned by the server and matched with the first patent text, and the text similarity between the object patent text contained in the first patent text list and the first patent text is larger than a first threshold value. According to the method and the device, the technical problem of low retrieval efficiency in related technologies is solved.

Description

technical field

[0001] The present invention relates to the field of computers, in particular to a text retrieval method and device, a storage medium and an electronic device. Background technique

[0002] In order to estimate the authorization prospect of the patent text to be applied for, many applicants often use the published patent application documents to search for the novelty of the patent text.

[0003] However, at present, in the process of using the patent text retrieval platform to perform the above-mentioned retrieval, users often need to preprocess the patent text to be retrieved, such as manually extracting keywords in the patent text in advance, and pre-writing the Boolean search formula corresponding to the patent text. Wait, and then use the processed content to achieve retrieval. That is to say, for the retrieval of patent texts, the operation complexity of the method provided by the related art is relatively high, which leads to the problem of low retrie...
