Research on Unseen Relation Linking Based on Transfer Learning and Fine-grained Features
摘要
Abstract
[Research purpose]In the era of explosive knowledge growth,knowledge graph question answering is facing the reality of in-formation demand and knowledge graph accelerated updates.Therefore,It is urgent to explore relation linking methods to maintain linking effectiveness and achieve accurate semantic matching between unseen relations and questions when relations are frequently updated.[Re-search method]To address the problems of inadequate model generalization and catastrophic forgetting,we adapt Adapter-Bert transfer learning framework.To address the problem of inadequate capture of discriminative semantic parts,we add entity feature and question transformation to model,and combine two different semantic representation methods which are dense vectors and abstract meaning formal-ized representation.[Research conclusion]The results show that the accuracy of our unseen relation linking method reached 98.80%,which is significantly higher than the Bert baseline model,and improves the effectiveness of unseen relation linking.关键词
