<p><b>Abstract</b>—In any electronic commerce system, the heterogeneity of product descriptions is a critical impediment to efficient business information exchange. In the A<scp>BECOS</scp> electronic commerce system, buyer agents, seller agents, and directory agents liaise with one another in e-commerce activities. Only when agents have a common ontology of product descriptions (also called product schemas) are they able to interact seamlessly in e-commerce activities. This gives rise to the Product Schema Integration problem (PSI); the problem of integrating heterogeneous schemas of a certain product into one globally compatible schema. In this paper, we adopt an integration approach based on product attribute synonyms. We give a formal definition of the problem and show that it is NP-complete. We contrast our approach of study to conventional schema integration in federated databases. We also propose a set of approximate algorithms for PSI and evaluate their performance.</p>
