The invention discloses a similar document retrieval method and device, electronic equipment and a storage medium. The technical problems that an existing similar document retrieval method is high in time cost and low in efficiency are solved. The method comprises the steps of obtaining a training document library; the training document library comprises a plurality of documents, and each document has a corresponding document ID; constructing a training data set according to the document; training a neural network by adopting the training data set to obtain a target neural network; receiving a target document, and generating a target training data set by adopting the target document; inputting the target training data set into the target neural network to obtain a target vector of the target document; and calculating a difference value between the target vector and a comparison vector in a preset database, and taking a document corresponding to the comparison vector of which the difference value is smaller than a preset threshold value as a similar document.
Description
technical field [0001] The present invention relates to the technical field of document retrieval, in particular to a similar document retrieval method, device, electronic equipment and storage medium. Background technique [0002] With the advancement of the information society, more and more documents (such as academic papers, novels, news, etc.) With technology, computers can still quickly retrieve documents that meet specific conditions (such as specific titles or specific keywords) from a huge document library. However, just retrieving titles or keywords is not enough to support all application scenarios. Sometimes it is necessary to retrieve a collection of similar documents of the target document. The release review system needs to detect whether an article marked as original is really original, and similar documents need to be eliminated during the corpus construction process. However, how to quickly retrieve a set of similar documents to a target document from a h...
