GO for gene documents
Annotating genes and their products with Gene Ontology codes is an important area of research. One approach for doing this is to use the information available about these genes in the biomedical literature. Our goal, based on this approach, is to develop automatic methods for annotation that could supplement the expensive manual annotation processes currently in place. Using a set of Support Vector Machines (SVM) classifiers we were able to achieve Fscores of 0.48, 0.4 and 0.32 for codes of the molecular function, cellular component and biological process GO hierarchies respectively. We explore thresholding of SVM scores, the relationship of performance to hierarchy level and to the number of positives in the training sets. We find that hierarchy level is important especially for the molecular function and biological process hierarchies. We find that the cellular component hierarchy stands apart from the other two in many respects. This may be due to fundamental differences in lin...
