In a mediator based approach, wrappers are built around individual information sources, that provide translation between the mediator query lan...

Interfaces of web information systems are highly heterogeneous. Additionally to schema heterogeneity they differ at the presentation layer. Web interface wrappers need to understand these interfaces in order to enable interoperation among web information systems. In contrast to the general scenario it has been observed that inside of application domains (e.g. air travel) hetergeneity is limited...
