    a concept structure mapper to map extracted expression to expression in a new domain using vocabulary for the new domain;

    a concatenation module to concatenate extracted expression with domain-general data; and

    a filter arrangement to identify and filter out unrealistic expression in at least one of mapped and concatenated expression.
