This paper proposes a novel end-to-end neural model to jointly extract entities and relations in a sentence.Unlike most exist-ing approaches,the proposed model uses a hybrid neural network to automatically learn sentence features and does not rely on any Natural Language Processing(NLP)tools,such as dependency parser.Our model is further capable of modeling multiple relations and their correspond-ing entity pairs simultaneously.Experiments on the CoNLL04 dataset demonstrate that our model using only word embeddings as input fea-tures achieves state-of-the-art performance.
