Extracting multiple relations from text sentences is still a challenge for Open Relation Extraction tasks . In this paper, we develop several Open RE models based on the bidirectional LSTM-CRF neuralnetwork and different contextualized word embedding methods . We also propose anew tagging scheme to solve overlapping problems and enhance models’performance . From the evaluation results and comparisons between models, weselect the best combination of tagging scheme, word embedder, and BiLSTM
