Uncertainty in data integration systems: automatic generation of probabilistic relationships

We propose a method for the automatic discovery of probabilistic relationships in the environment of data integration systems. Dynamic data integration systems extend the architecture of current data integration systems by modeling uncertainty at their core. Our method is a probabilistic word sense disambiguation (PWSD), which allows to automatically lexically annotate (i.e. annotation w.r.t. a thesaurus/lexical resource) the schemata of a given set of data sources to be integrated. From the annotated schemata we derived the probabilistic lexical relationships that are inserted in the Probabilistic Common Thesaurus (PCT) and are added together to the structural relationships.
