摘　　要：传统的生物医学实验方法验证circRNA与疾病之间的关系存在耗时、耗力且成本过高的问题,为此提出基于三部图融合相似性的circRNA与疾病关联预测研究的模型(FSTPGCDA). FSTPGCDA引入circRNA-disease关联信息、circRNA-gene关联信息、circRNA序列信息和疾病语义信息.进行拉普拉斯特征映射和Jaccard指标的融合相似性计算得到相似性矩阵,将不同相似性算法得到的相似性矩阵加权融合得到融合相似性矩阵.利用circRNA-disease关联矩阵和circRNA-gene关联矩阵构建gene-circRNA-disease三部图.通过融合相似性方法为三部图分配初始资源,使用贪心算法进行资源分配.实例验证表明,FSTPGCDA的预测性能和鲁棒性较好.Traditional biomedical experimental methods for verifying the relationship between circRNA and disease are time-consuming,laborious,and costly.Therefore,a model called FSTPGCDA was proposed for circRNA-disease association prediction research,which was based on the fusion of tripartite graph and fusion similarity.FSTPGCDA incorporated circRNA-disease association information,circRNA-gene association information,circRNA sequence information,and disease semantic information.The similarity matrix was obtained by combining Laplacian eigenmaps and Jaccard index for fusion similarity calculation.The fusion similarity matrix was generated by weighting the similarity matrices obtained from different similarity algorithms.The gene-circRNA-disease tripartite graph was constructed using the circRNA-disease association matrix and circRNA-gene association matrix.The initial resource allocation was performed using the fusion similarity,and resource allocation was carried out using a greedy algorithm.The experimental validation demonstrated that FSTPGCDA exhibited good predictive performance and robustness.
