Web7 de set. de 2024 · Abstract. The target of multi-label text classification (MLTC) is to annotate texts with the most relevant labels from a candidate label set. In MLTC models, representing a true label as a one-hot vector is a common practice. However, the inadequate one-hot representation may ignore the similar predicted scores between … WebMulti-label text classiﬁcation allows for the co-existence of more than one label in a single doc-ument, thus, there are semantical correlations a-mong labels because they may share the same subsets of document. Meanwhile, the document may be long and complicated semantic informa-tion may be hidden in the noisy or redundant con-tent. perl round function
