11. The method of claim 10 wherein said determining further comprises:

measuring a similarity between a first set of terms and a second set of terms;

wherein said first set of terms comprises said first concepts of interest and said second set of terms comprises said second concepts of interest.

12. The method of claim 10 wherein said determining an overall relevance between said relevant first concepts of interest and said relevant second concepts of interest further comprises:

measuring a term frequency between a first vector C and a second vector A;

wherein said first vector comprises said first concepts of interest, ci, and said second vector comprises said second concepts of interest, aj; said first vector having m concepts and said second vector having n concepts; and

comparing said first vector and said second vector to obtain a third vector Vij, wherein said third vector comprises an indication of a match of concepts common to said first vector and said second vector.

13. The method of claim 12 further comprising:

determining a number of indications of matches, Wij in said third vector, Vij;

determining a length, Xi, of said third vector, Vij;

determining a value, ci; and

determining a similarity value, Sij, according to the relationship: S ij = ( W ij X i ) c i .
