【Abstract】 Gene Ontology is widely applied to mine differentially expressed functional classes based on the microarray experiments.However,there still are many problems of microarray technology,such as the incomplete coverage of measured genes over genome and measurement noise.We explore how such problems will affect on the mining outcomes.The results suggest that the discovered differentially expressed functional classes are robust to the factors of incomplete coverage and measurement noise.更多还原
