- Abstract:
-
Knowledge graph representation learning is a process of representing knowledge graph entities and relations in a multidimensional vector through specific rules. Existing representation learning methods are mostly used to solve the single-hop knowledge graph question-and-answer task, but their multi-hop reasoning ability cannot meet the actual demand. To improve the multi-hop reasoning ability, a knowledge graph representation learning model combining entity description and path information is proposed. First, the learning vector of entity and relation representation is obtained using the pre-training language model RoBERTa. Second, OPTransE is used to transform the knowledge graph into a vector integrating the path information of an ordered relation. Finally, the total energy function is constructed to fuse the vectors of entity description and path information. The feasibility and validity of the model are verified by comparing its performance in a link prediction task with that of the mainstream knowledge graph representation learning model.
