Abstract

Knowledge graphs such as DBpedia, Freebase or Wikidata always contain a taxonomic backbone that allows the arrangement and structuring of various concepts in accordance with hypo-hypernym (“class-subclass”) relationship. With the rapid growth of lexical resources for specific domains, the problem of automatic extension of the existing knowledge bases with new words is becoming more and more widespread. In this talk, she addresses the problem of taxonomy enrichment which aims at adding new words to the existing taxonomy. The author presents a new method which allows achieving high results on this task with little effort, described in [16]. It uses the resources which exist for the majority of languages, making the method universal. The method is extended by incorporating deep representations of graph structures like node2vec, Poincaré embeddings, GCN etc. that have recently demonstrated promising results on various NLP tasks. Furthermore, combining these representations with word embeddings allows them to beat the state of the art.
