• Question is for the Presentation: Joshua Taylor presents Discovering Simple Mappings Between Relational Database Schemas and Ontologies
• Question is asked by: Joshua Taylor
• The Question is: What's up with this evaluation? Is the system really only being compared against one other system?
• Question is answered by: Joshua Taylor
• The Answer is: The Marson system is compared against the 2006 Ronto system which was developed by a team disjoint with the authors. 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.
