20. A computer-implemented method comprising: receiving a search query including a name of an entity; determining a measure of how rare the name is in a population, and wherein determining a measure of how rare the name is in a population 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 obtaining additional information to assist in answering the query, in response to the determined measure.
