Selecting Informative Genes from Microarray Dataset by Incorporating Gene Ontology
Selecting informative genes from microarray experiments is one of the most important data analysis steps for deciphering biological information imbedded in such experiments. However, due to the characteristics of microarray technology and the underlying biology, namely large number of genes and limited number of samples, the statistical soundness of gene selection algorithm becomes questionable. One major problem is the high false discover rate. Microarray experiment is only one facet of current knowledge of the biological system under study. In this paper, we propose to alleviate this high false discover rate problem by integrating domain knowledge into the gene selection process. Gene Ontology represents a controlled biological vocabulary and a repository of computable biological knowledge. It is shown in the literature that gene ontologybased similarities between genes carry significant information of the functional relationships [3]. Integration of such domain knowledge into gene...
