针对现有的特征提取方法忽略文本局部和全局联系的问题,提出了基于多尺度特征提取的层次多标签文本分类方法。首先,设计了多尺度特征提取模块,对不同尺度特征进行捕捉,更好地表示文本语义。其次,将层次特征嵌入文本表示中,得到具有标签特征的文本语义表示。最后,在标签层次结构的指导下对输入文本构建正负样本,进行对比学习,提高分类效果。在WOS、RCv1-v2、NYT和AAPD数据集上进行对比实验,结果表明,所提模型在评价指标上表现出色,超过了其他主流模型。此外,针对层次分类提出层次Micro-F 1和层次Macro-F 1指标,并对模型效果进行了评价。

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, v, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
