New graph reranking method enhances automated subject indexing

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TAGHN, a novel approach to automated subject indexing that leverages graph reranking to improve descriptor assignment. Unlike previous methods that treat vocabularies as flat lists, TAGHN incorporates semantic relationships from thesauri by constructing a heterogeneous graph. This method estimates descriptor relevance based on both document similarity and the thesaurus neighborhood, outperforming existing cross-encoder and XMLC classifiers on the STW economic thesaurus. AI

IMPACT This method could improve the accuracy and efficiency of organizing and retrieving research papers and other documents.

    Reading the Neighborhood: Text-Attentive Graph Reranking for Automated Subject Indexing

    Subject indexing assigns descriptors from a controlled vocabulary to bibliographic records, a task characterized by thousands of labels, few positive examples per label, and a long tail of rarely used descriptors. Existing extreme multi-label classifiers treat the vocabulary as a…
