20. The computer program product of claim 19 , wherein said computing a second score representing a degree of match between said compared query LAT with said candidate answer AT includes: matching said candidate answer against instances in a corpus or a knowledge base; retrieving a type associated with an instance in the corpus or the knowledge base; and, matching said query LAT with said retrieved type to produce a type coercion (TyCor) value, said second score comprising said TyCor value.
20. The computer program product of claim 19 , wherein said computing a second score representing a degree of match between said compared query LAT with said candidate answer AT includes: matching said candidate answer against instances in a corpus or a knowledge base; retrieving a type associated with an instance in the corpus or the knowledge base; and, matching said query LAT with said retrieved type to produce a type coercion (TyCor) value, said second score comprising said TyCor value. 21. The computer program product of claim 20 , wherein a query has up to n candidate LATs, said combining to provide said total score is a summation according to: 
 (confidence score LAT1 )(TyCor LAT 1 )+(confidence score LAT2 )(TyCor LAT 2 )+ . . . +(confidence score LATn )(TyCor LATn ) wherein confidence score LAT1 , confidence score LAT2 , and confidence score LATn are produced confidence values representing estimated accuracies of each determined LAT of said query, and TyCor LAT1 , TyCor LAT2 , and TyCor LATn are the produced type coercion (TyCor) values of a candidate answer with each LAT.
