Abstract:As domain knowledge evolves, new concepts (entities) continuously emerge, leading to a decrease in the coverage of existing taxonomies with hierarchical structures, thus necessitating the continual expansion of these taxonomies to include new concepts. Due to the relationships (“contain”, “disjoint”, and “intersect”) between the boxes, which can effectively represent asymmetric hierarchies, box embeddings have been successfully applied in taxonomy expansion. However, existing models that use box embeddings for… Show more
