Algorithm 2. Algorithm 2 for the identification and the comparison of pertinent target sets in the generic compact representation (see example in figure 6) for their comparison to a given query set. The node data structure has the following fields: tag for the potentially pertinent tag, children and parent that point to child and parent nodes, common which is the set of common elements with the query, #differing for the number of elements differing with the query set, size for the size of the set this node represents.
