Precision vs. Recall for different values of Specificity, s .Paired precision (P) and recall (R) results as a function of specificity broken out by inclusive "family groups" as mentioned in the text. Note that recall is bounded above by precision, due to the need to cut off the number of GOC cluster heads considered based on the number of requested results. The x axis indicates the value of specificity (s); the y axis represents the value of precision or recall, as a percentage.
