6. The computer based system according to claim 5 , wherein the confidence score indicates the cosine product between the semantic vector related to the incoming case and its associated centroid vector, wherein 0 represents the minimal confidence when d(x,c(x))=−1 or x=−c(x) and 1 represents the maximal confidence when d(x,c(x))=1 or x=c(x).
5. The computer based system according to claim 1 , wherein the one or more recommended workflow solutions are assigned a confidence score, wherein the confidence score is defined as Score ( x ) = 1 + d ⁡ ( x , c ⁡ ( x ) ) 2 , wherein the semantic vector corresponding to the incoming case is x, the associated cluster centroid vector of x is c(x), and the cosine product between vector x and y in the semantic constraint space is d(x, y).
