Comparison-shopping brokers can create value to transactions between consumers and vendors by aggregating services and product information that were traditionally offered by separate vendors, thus reducing search costs and contributing for efficiency on Web electronic markets. Specifically in retail markets where the diversity of product data is greater, it is not always easy to find what a consumer is looking for on the Web. This paper presents an architecture for comparison-shopping brokers that provides precise information about products and vendors to consumers, retrieving this information in unstructured sources like the Web and heterogeneous business data on online stores. We also present and discuss a case study of this architecture in use, the WhereBuy broker, detailing its product comparison process.
