ABSTRACT=Emerging evidence indicates that circRNA can regulate various diseases. However, the mechanisms of circRNA in these diseases have not been fully understood. Therefore, detecting potential circRNA-disease associations has far-reaching significance for pathological development and treatment of these disease. In recent years, deep learning models are used in association analysis of circRNA-disease, but a lack of circRNA-disease association data limits further improvement. Therefore, there is an urgent need to mine more semantic information from data. In this paper, we propose a novel method called Semantic Association Analysis by Embedding and Deep learning (SAAED), which consists of two parts, a neural network embedding model called Entity Relation Network (ERN) and a Pseudo-Siamese network for analysis (PSN). ERN can fuse multiple sources of data and express the information with low-dimensional embedding vectors. PSN can extract the feature between CircRNA and disease for the association analysis. CircRNA-disease, CircRNA-miRNA, disease-gene, disease-miRNA， disease-lncRNA and disease-drug association information are used in this paper. More association data can be introduced for analysis without restriction. Based on CircR2Disease benchmark dataset for evaluation, five-fold cross-validation experiment showed an AUC of 98.92%, an accuracy of 95.39%, and a sensitivity of 93.06%. Compared with other state-of-the-art models, SAAED achieves the best overall performance. SAAED can expand the expression of the biological related information and is an efficient method for predicting potential circRNA-disease association.
