Abstract
One important step in integrating heterogeneous databases is
matching equivalent attributes: Determining which fields in
two databases refer to the same data. The meaning of information
may be embodied within a database model, a conceptual schema,
application programs, or data contents.
Integration involves extracting semantics, expressing them
as metadata, and matching semantically equivalent data elements.
We present a procedure using a classifier to categorize attributes
according to their field specifications and data values, then
train a neural network to recognize similar attributes. In our
technique, the knowledge of how to match equivalent data
elements is ``discovered'' from metadata, not ``pre-programmed''.
