Title:
TEXT CLUSTERING METHOD, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/126944
Kind Code:
A1
Abstract:
The embodiments of the present disclosure relate to a text clustering method, a device and a storage medium, which relate to the field of information processing. The method comprises: determining a word frequency - inverse document frequency of each word in a plurality of first texts; removing entity identifiers from a plurality of text titles in the plurality of first texts, so as to generate a plurality of non-entity titles; on the basis of a word frequency - inverse document frequency, determining a plurality of first feature representations associated with the plurality of non-entity titles; on the basis of the plurality of first feature representations and a first density radius, performing density clustering on the plurality of first texts, so as to generate a plurality of first text clusters and a plurality of un-clustered second texts; on the basis of a word frequency - inverse document frequency, determining a plurality of second feature representations associated with the plurality of second texts; and on the basis of the plurality of second feature representations and a second density radius, performing density clustering on the plurality of second texts, so as to generate a plurality of second text clusters, wherein the second density radius is greater than the first density radius. Therefore, multi-level text clustering can be realized.
