Context representation of product data

This paper investigates the context representation of ad hoc product data that distribute in different semantic communities especially in small and medium sized enterprises through the analysis of the problems in extracting, mediating and comparing product contexts. The problem analysis leads to a proposal for a novel context representation model that separates the representation process into two steps: transform irregular local product definitions into canonical local product representations and map canonical local product representations onto common product representations. This model serves as the foundation to further compare product contexts between different semantic communities.
