Solving Integration Problems of e-commerce standards and initiatives through ontological mappings

The proliferation of different standards and joint initiatives for the classification of products and services (UNSPSC, e-cl@ss, RosettaNet, NAICS, SCTG, etc.) reveals that B2B markets have not reached a consensus on coding systems, level of detail of their descriptions, granularity, etc. This paper shows how these standards and initiatives, which are built to cover different needs and functionalities, can be integrated using a common multi-layered knowledge architecture through ontological mappings. This multi-layered ontology will provide a shared understanding of the domain for applications of e-commerce, allowing information sharing and interoperation between heterogeneous systems. We will present a tool called WebPicker and a method for integrating these standards and initiatives, enriching them and obtaining the results in different formats using the WebODE platform. As an illustration, we show a case study on the computer domain, presenting the ontological mappings between UNSPSC, e-cl@ss, RosettaNet and an electronic catalogue from an e-commerce platform.
