The comparison with the ''Simple'', ''VDoc'', ''Valid'' systems seems a bit odd. The authors have developed a four-phase process for generating mappings, and have a reason for designing each phase. They then compared their system against crippled versions of itself. It is not particularly surprising, in my opinion, that it tends to come out on top (although, in the case of OBSERVER/Bibiography, the ''Valid'' system even does a little better). Rather than having shown that ''Marson'' is a good system (compared to other systems in the world), it seems that the combination of techniques present in ''Marson'' is better (usually) than a subset of those techniques. What's up with this evaluation? Is the system really only being compared against one other system?
