A Method for Constructing Open-Domain Chinese Entity Hypernym Hierarchical Structure

摘要

Entity relation is an essential component of some famous knowledge bases,such as Freebase,Yago and Knowledge Graph,while the hyponymy plays an important role in entity relations that show the relationship between the more general terms(hypernyms)and the more specific instances of the terms(hyponyms).In this paper,we present a comprehensive scheme of open-domain Chinese entity hypernym hierarchical construction.Some of the most important unsupervised and heuristic approaches for building hierarchical structure are covered in sufficient detail along with reasonable analyses.We experimentally evaluate the proposed methods and compare them with other baselines.The result shows high precision of our method and the proposed scheme will be further improved with larger scale corpora.
