Comparison between DIAN and MGI Ontological Assignments
| Results from the comparative approach are shown. A number of intrinsic problems were identified from this approach, such that type I and type II variances described here are for comparative purposes only and cannot be interpreted strictly as type I and II errors. |

| DIAN assignments made to a group of well-characterized, nonredundant mouse sequences were compared to assignments made by the MGI to the GO Process and Function ontologies. GO modes corresponding to DIAN nodes are listed, along with the abbreviated essential concept from theDIAN Role ontology. For brevity, only the highest level GO nodes are listed. The number of sequences whose assignment is shared to both sets of ontologies is indicated (DIAN and GO), as well as the number of sequence assignments which differed (DIANonly, GO only). These numbers are used to calculate Type I and II variation using the following equations: Type I variation =DIANonly/(DIAN and GO +DIAN only + GO only); Type II variation = GO only/(DIAN and GO +DIAN only + GO only); Sensitivity =DIAN and GO/(DIAN and GO + GO only); Selectivity =DIAN and GO/(DIAN and GO +DIAN only). Sensitivity is defined as the ability of the DIAN algorithm to make what are believed to be all possible correct assignments. Selectivity is defined as the ability of the DIANalgorithm to not make what is believed to be an incorrect assignment. |
