Drug-drug interaction (DDI) study is an important aspect of therapy management and drug efficacy. DDI study investigates how drugs interact with each other and determine whether these interactions may lead to dire effects or nullify the therapeutic effects of each other. In this paper we model metabolic pathways of drugs that include the reaction effects between drugs and the related enzymes. By modeling...
The ability to reason over large scale data and return responsive query results is widely seen as a critical step to achieving the Semantic Web vision. We describe an approach for partitioning OWL Lite datasets and then propose a strategy for parallel reasoning about concept instances and role instances on each partition. The partitions are designed such that each can be reasoned on independently...
Detection of cyber-attacks is a major responsibility for network managers and security specialists. Most existing Network Intrusion Detection systems rely on inspecting individual packets, an increasingly resource consuming task in today's high speed networks due to the overhead associated with accessing packet content. An alternative approach is to detect attack patterns by investigating IP flows...
