• Abstract: Accurate identification of disease genes has consistently been one of the keys to decoding a disease's molecular mechanism. Most current approaches focus on constructing biological networks and utilizing machine learning, especially, deep learning to identify disease genes, but ignore the complex relations between entities in the biological knowledge graph. In this paper, we construct a biological knowledge graph centered on diseases and genes, and develop an end-to-end Knowledge graph completion model for Disease Gene Prediction using interactional tensor decomposition (called KDGene). KDGene introduces an interaction module between the embeddings of entities and relations to tensor decomposition, which can effectively enhance the information interaction in biological knowledge. Experimental results show that KDGene significantly outperforms state-of-the-art algorithms. Furthermore, the comprehensive biological analysis of the case of diabetes mellitus confirms KDGene's ability for identifying new and accurate candidate genes. This work proposes a scalable knowledge graph completion framework to identify disease candidate genes, from which the results are promising to provide valuable references for further wet experiments.

• Improving Disease Comorbidity Prediction Based on Human Interactome with Biologically Supervised Graph Embedding [0.0]
  Comorbidity carries significant implications for disease understanding and management. Human interactome, as a large incomplete graph, presents its own challenges to extracting useful features for comorbidity prediction. Biologically Supervised Graph Embedding (BSE) allows for selecting most relevant features to enhance the prediction accuracy of comorbid disease pairs.

  This paper presents SimpleGermKG, an automatic knowledge graph construction approach that connects germline genes and diseases. For the extraction of genes and diseases, we employ BioBERT, a pre-trained BERT model on biomedical corpora. For semantic relationships between articles, genes, and diseases, we implemented a part-whole relation approach. Our knowledge graph contains 297 genes, 130 diseases, and 46,747 triples.
