| Abstract: | Extracting relational triples is a basic task for large-scale knowledge graph construction. In order to improve the ability of extracting overlapped relation triples and multi-slot relation triples, this paper proposes BSLRel, an end-to-end relation triple extraction model based on neural network. Specifically, BSLRel model converts the relation triplet extraction task into a cascade binary sequence labeling task,which consists of a new multiple information fusion structure “Conditional Layer Normalization” to integrate information. With BSLRel, we participate in the “Relation Extraction” task organized by “the 2020 Language and Intelligence Challenge” and achieve Top 5 among all competitive models. |
