Abstract

Inferring heterogeneous biological networks from heterogeneous data.

With the advancement of quantitative biology, there has been a dramatic 
increase in functional genomic data. Using these heterogeneous genomic 
data which includes protein-protein interaction, gene expression, 
localization, and gene knockout studies has enabled researchers to 
construct functional gene networks. In functional gene networks, each 
edge represents the probabilistic support for a functional relationship 
between two genes.

However in practice, the goal of biology is to understand further depth 
of the relationship between genes, beyond the abstract notion of a 
functional relation. In this work, we expand the depth and breadth of 
functional gene networks. We use prior biological knowledge of gene 
interactions types to construct an interaction ontology, which enables 
us to predict interaction types between genes using a Bayesian 
hierarchical framework. Ultimately, our work provides further insight 
into the genetic wiring of the cell.
