document: Semantic B2B integration : issues in ontology-based approaches Solving queries to support e-commerce transactions can involve retrieving and integrating information from multiple information resources . Often , users do n't care which resources are used to answer their query . In such situations , the ideal solution would be to hide from the user the details of the resources involved in solving a particular query . An example would be providing seamless access to a set of heterogeneous electronic product catalogues . There are many problems that must be addressed before such a solution can be provided . In this paper , we discuss a number of these problems , indicate how we have addressed these and go on to describe the proof-of-concept demonstration system we have developed
