1. A computer-implemented method comprising: identifying a name in a document; determining a rarity indicator for the name, the rarity indicator representing a measure of how rare the name is in a population, and wherein determining a rarity indicator for the name further comprises the formula: 
 P (nameUniqueness)=1/(( H*P (name))+1) wherein H denotes the size of the human population likely to be referenced in the document, P(name) is the name match probability score, and P(nameUniqueness) is the probability of name uniqueness; and defining a hyperlink for the name based on the rarity indicator.

The computer-implemented method of claim 1 , wherein the rarity indicator is a quantity based on a size of a human population, a probability of drawing a first portion of the name at random, and a probability of drawing a second portion of the name at random.
