13. An apparatus comprising: a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to: parse content into one or more conceptual units, wherein each conceptual unit comprises a portion of text of the content that is associated with a single concept; for each conceptual unit in the one or more conceptual units, identify a term in the conceptual unit that has a synonym to be utilized during natural language processing of the content; determine a first measure of relatedness of the term to at least one other term in the conceptual unit; determine a second measure of relatedness of the synonym of the term to the at least one other term in the conceptual unit; determine whether or not to utilize the synonym when performing natural language processing on the conceptual unit based on the first measure of relatedness and the second measure of relatedness; and perform natural language processing on the content based on results of determining whether or not to utilize the synonym, wherein the first measure of relatedness is calculated as the sum, from 1 to N, where N is a number of remaining words in the conceptual unit, of the quantity 1/N*(f(Wn, ORIG)), where f( ) is a semantic distance function, W is the set of remaining words in the conceptual unit, and ORIG is the term, and wherein the second measure of relatedness is calculated as the sum, from 1 to N, of the quantity alpha*1/N*(f(Wn, SYN)), where alpha is a constant, and SYN is the synonym, wherein the instructions further cause the processor to determine whether or not to utilize the synonym when performing natural language processing on the conceptual unit at least by: comparing the first measure of relatedness to the second measure of relatedness using the following relationship: ∑ n = 1 N ⁢ 1 N ⁢ f ⁡ ( W n , ORIG ) ≤ ∑ n = 1 N ⁢ α ⁢ 1 N ⁢ f ⁡ ( W n , SYN ) ⁢ { pass fail } ; and determining to utilize the synonym when performing natural language processing on the conceptual unit in response to the relationship being satisfied.

The apparatus of claim 13 , wherein the instructions further cause the processor to determine whether or not to utilize the synonym when performing natural language processing on the conceptual unit at least by: comparing the first measure of relatedness to the second measure of relatedness; and determining to utilize the synonym when performing natural language processing on the conceptual unit in response to the first measure being greater than or equal to the second measure.
