Abstract
As an important part of information extraction, relationship extraction aims to extract the relationships between given entities from natural language text. On the basis of the pre-training model R-BERT, this paper proposes an entity relationship extraction method that integrates entity dependency path and pre-training model, which generates a dependency parse tree by dependency parsing, obtains the dependency path of entity pair via a given entity, and uses entity dependency path to exclude such information as modifier chunks and useless entities in sentences. This model has achieved good F1 value performance on the SemEval2010 Task 8 dataset. Experiments on dataset show that dependency parsing can provide context information for models and improve performance.
