Hierarchical Metadata-Aware Document Categorization under Weak Supervision
[article]
2020
Preserved Fulltext
Hence, this paper studies how to integrate the label hierarchy, metadata, and text signals for document categorization under weak supervision. ...
Categorizing documents into a given label hierarchy is intuitively appealing due to the ubiquity of hierarchical topic structures in massive text corpora. ...
CONCLUSIONS We present HiMeCat, an embedding-based generative framework for hierarchical metadata-aware document categorization under weak supervision. ...
