Event extraction for pathway construction

relatopn extractionWe propose a relation extraction step to  find the relation between GGI and cancer. In the event extraction step, we use Turku event extraction system to nd interaction between genes. We nd a candidate sentence that has gene and event by Turku system. Then, we fi nd an agent gene, a kind of activator or suppressor of gene expression, in the sentence parsing tree. To check that candidate sentence has relation between cancer and gene interaction, we fir st check that the evidence sentence has prostate cancer terms.
