| Abstract: | Knowledge reasoning is an important method to solve the problem of lack of knowledge in the knowledge graph. The knowledge reasoning method in the large-scale knowledge graph still has the problems of poor interpretability, low reasoning accuracy and efficiency. This paper proposes a method RLPTransE that combines knowledge representation with deep reinforcement learning. Firstly, it uses the knowledge representation learning method to map the knowledge graph to the vector space containing the semantic information of the triples, and establishes a reinforcement learning environment in the space. Then, it trains through the single-step optimization strategy network and the multi-step reasoning strategy network to enable the reinforcement learning agent to efficiently mine the reasoning rules and complete the reasoning in the process interacting with the environment. According to experimental results on public datasets, compared with state-of-the-art methods, the proposed method achieves better performance in reasoning tasks for large-scale datasets. |
