Taxonomy Completion with Probabilistic Scorer via Box Embedding

1 code implementation18 May 2023 Wei Xue, Yongliang Shen, Wenqi Ren, Jietian Guo, ShiLiang Pu, Weiming Lu

Specifically, TaxBox consists of three components: (1) a graph aggregation module to leverage the structural information of the taxonomy and two lightweight decoders that map features to box embedding and capture complex relationships between concepts; (2) two probabilistic scorers that correspond to attachment and insertion operations and ensure the avoidance of pseudo-leaves; and (3) three learning objectives that assist the model in mapping concepts more granularly onto the box embedding space.
