Abstract
Web Warehouses (WW) are data warehouses that consolidate data from the Web. The process of building them presents several challenges, most of them related to the autonomy and dynamicity of Web sources. In this context, managing quality aspects becomes a fundamental issue since information about quality is needed to properly select Web sources to populate the WW. Additionally, measuring and propagating quality values to the WW might provide final users with valuable information to improve decision-making processes. In this chapter, we present a reference architecture for quality aware Web Warehouses, which specifies the main components to evaluate and manage quality aspects through all the life cycle of a WW and considers quality regarding data and services.
