Document Type and Number:
WIPO Patent Application WO/2022/134343
Kind Code:
A1
Abstract:
A document clustering method, a document clustering apparatus (400), an electronic device (500), and a storage medium. The document clustering method comprises: the document clustering apparatus (400) obtains N documents to be clustered, N being an integer greater than 1 (101); the document clustering apparatus (400) determines a co-citation similarity between any two documents among the N documents (102); according to the co-citation similarity between the any two documents, the document clustering apparatus (400) performs first clustering on the N documents to obtain M clusters, the M clusters corresponding to K documents to be clustered, M being an integer greater than or equal to 1, and K being an integer less than or equal to N (103); and the document clustering apparatus (400) performs second clustering on the remaining (N-K) documents so as to fuse the (N-K) documents into the M clusters (104). The method helps to increase the accuracy of document clustering.
