Abstract
A method includes coarse clustering and secondary fine clustering. First, semantic vectors respectively corresponding to a plurality of texts are determined by using a semantic representation model, and a similarity matrix between the plurality of texts is determined based on the semantic vectors of the plurality of texts. Next, in a coarse clustering phase, M similar texts with maximum similarities respectively corresponding to the plurality of texts are determined from the similarity matrix, and the corresponding texts are used as selected central texts when the similarities corresponding to the M similar texts are greater than a threshold, to quickly remove a large amount of isolated noise. Then, candidate class clusters are obtained based on data corresponding to the central texts in the similarity matrix, candidate class clusters with a cross-text are combined, and then secondary fine clustering is performed on a combined class cluster.
