   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.
