| Outline of Final Research Achievements |
It is not explicit what relationship exists between the various information (term) in the database. In this research, the purpose is to find a new relationship between information by integrated analysis. First, correlation detection of term information to describe gene function was performed, and it was found that the cell localization information of protein has high correlation with information such as other functions. As a result of investigating the method for enlarging the scale, we applied matrix factorization approach to make it large scale, by which we can skip for computation rigorous correlation factors. At the same time, complex concepts expressed by plural terms can be extracted automatically. When the technique was applied to omics data such as gene expression and mutation, we could find new candidates of cancer biomarkers.
