- W3182020042 abstract "• A knowledge base graph embedding module is constructed to extend the generality of the visual question answering model based on knowledge base in this paper. • This paper constructs two experimental knowledge bases: DBV and DBA through a series of knowledge base preprocessing methods. • The DBV knowledge base constructed in this paper has strong entity correspondence, and its knowledge base embedding effect is very good. In this paper, a knowledge base graph embedding module is constructed to extend the versatility of knowledge-based VQA (Visual Question Answering) models. The knowledge base graph embedding module constructed in this paper extracts core entities from images and text, and maps them as knowledge base entities, then extracts the sub-graphs closely related to the core entities, and converts the sub-graphs into low-dimensional vectors to realize sub-graph embedding. In order to achieve good subgraph embedding, we first extracted two experimental knowledge bases with rich semantics from DBpedia: DBV and DBA. Based on these two knowledge bases, this paper selects several excellent models in knowledge base embedding as test models, including SE (structured embedding),SME(semantic matching energy function), and TransE model to produce link prediction. The results show that there is a clear correspondence between the entities of the DBV, which can achieve excellent node embedding. And the TransE model can achieve a good knowledge base embedding, so we built the knowledge base graph embedding module based on TransE. And then we construct a VQA model ( KBSN ) based on the knowledge base graph embedding. Experimental results on VQA2.0 and KB-VQA data sets prove that the knowledge base graph embedding module improves the accuracy." @default.
