Cross-border Ethnic Cultural Entity Relation Extraction Based on Pointer Annotation
The information extraction in the field of cross-border ethnic culture is challenged by rich domain words and the high density distribution of entities caused the overlapping entity relationships.To better capture the domain information,this paper proposes a cross-border ethnic cultural entity relationship extraction method based on pointer annotation.The domain lexicon is integrated into the character vector representation to enhance domain entity labe-ling.The problem of overlapping entity relations is solved through multi-layer pointer labeling in the field of cross-border ethnic culture.The experimental results show that the F1 value of the proposed method has improved by 2.34%compared with the baseline method on the cross-border ethnic cultural entity relation extraction dataset.
