Webmodels ignore the problem of long-tail relations, which makes it challenging to extract comprehen-sive information from plain text. Long-tail relations are important and … WebAbstract: Relation Extraction (RE) is a crucial step to complete Knowledge Graph (KG) by recognizing relations between entity pairs. However, it usually suffers from the long-tail issue, especially when using distantly supervision algorithm. In this paper, inspired by the rich semantic correlations between head relations and tail relations, we proposed a …
