Mediatability: Estimating User Effort to Mediate Between Two XML Schemas

Overview

Mediation and integration of data are significant challenges because the number of services on the Web, and heterogeneities in their data representation, continue to increase rapidly. To address these challenges we introduce a new measure, mediatability, which is a quantifiable and computable metric for the degree of human involvement in XML schema mediation. Our research is to create an efficient algorithm to compute mediatability. We also present an experimental study to analyze how semantic annotations affect the ease of mediating between two schemas. This approach is validated by comparing mediatability scores generated using the system with user-perceived difficulty.
