The construction of medical knowledge graph based on electronic medical records is of great significance to the development of medical technology,where entity and relation extraction plays a pivotal role.In this paper,we propose a Parallel Interactive Attention Network(PIAN)which can fully exploit the correlation between entity and relation.Since there are few Chinese medical entity and relation annotation datasets,we construct an entity and rela-tion extraction dataset based on Chinese electronic medical records(CEMRIE),formulate the corpus annotation specification with medical experts,and give the benchmark results based on our proposed model.
