XML Schema Element Similarity Measures: A Schema Matching Context Authors: Alsayed Algergawy, Richi Nayak, Gunter Saake
Abstract:
In this paper, we classify, review, and experimentally compare major methods that are exploited in the definition, adoption, and utilization of element similarity measures in the context of XML schema matching. We aim at presenting a unified view which is useful when developing a new element similarity measure, when implementing an XML schema matching component, when using an XML schema matching system, and when comparing XML schema matching systems.
I commend the entire paper for your reading but would draw your attention to one of the conclusions in particular:
Using a single element similarity measure is not sufficient to assess the similarity between XML schema elements. This necessitates the need to utilize several element measures exploiting both internal element features and external element relationships.
Does it seem plausible that single subject similarity measures can work but it is better to use several subject similarity measures?
Questions:
- Compare this paper to any recent (last two years) paper on database schema similarity. What issues are the same, different, similar? (sorry, could not think of another word for it) (2-3 pages, citations)
- Create an annotated bibliography of ten (10) recent papers on XML or database schema similarity (excluding the papers in #1). (4-6 pages, citations)
- How would you use any of the similarity measures you have read about in a topic map? Or is similarity enough? (3-5 pages, no citations)
