On the Integration of Heterogeneous Information Systems in
Large Scientific Collaborations
After a short introduction into the mainstream principles and
architectures related to Information Integration (e.g. global
information systems, mediation, and schema mapping), this talk will
discuss one of its aspects, the source integration problem (i.e., the
resolution of semantic schema mismatch) in the context of the
information infrastructure of large scientific collaborations.
Environments like these have properties that render previous
approaches infeasible, such as rapidly changing requirements, large
data sets, and the impossibility to create common "global" integration
models. We present a combined model management and query rewriting
approach for solving these problems and conclude with a brief
demonstration of a practical system that we have implemented, which
uses new, scalable query rewriting algorithms based on techniques from
both AI and databases.
