An Approach Based on Multilevel Convolution for Sentence-Level Element Extraction of Legal Text

Zhe Chen, Hongli Zhang, Lin Ye, Shang Li, Peng Li
2021 Wireless Communications and Mobile Computing  
In this paper, we propose a sentence-level model of legal text element extraction based on the structure of multilabel text classification.  ...  To our best knowledge, it is one of the first attempts to apply a multilabel classification algorithm for element extraction of legal text.  ...  The difference between legal text on the Chinese legal text and the general multilabel and general text lies in the uncertainty of the number of text classification task characters  ...
