Figure 9

Stable and unstable ontology regions in GO Molecular Functions using the Region Analyzer. The figure shows the region stability of GO Molecular functions concepts between 2009-09 and 2011-03 (monthly versions). Red (green) categories evolved heavily (marginally) in the observation period and are thus unstable (stable). (a) Region stability of slim terms on the first level of GO Molecular function. (b) Region stability of the detected significant result concepts and their parents (from our application scenario in Figure 4).
