TaxoEmbed

About

TaxoEmbed is a supervised distributional framework for hypernym discovery which operates at the sense level, enabling large-scale automatic acquisition of disambiguated taxonomies. TaxoEmbed exploits semantic regularities between hyponyms and hypernyms in embeddings spaces to learn a hypernym transformation matrix, and integrates a domain clustering algorithm to produce domain-specific models that are sensitive to the target data. Experiments on ten different domains show that TaxoEmbed is flexible and robust enough to accommodate heterogeneous training pairs, drawn from manually curated knowledge bases as well as OIE-derived resources.
