Linked Open Data has grown into a large and recognised source of data, however its uptake and commercial exploitation does not yet reflect its potential value. Two factors with potential to contribute to the value of data are correlating previously uncorrelated data and providing answers based on the data. We present a data-centric question answering portal, developed within the CODE project, which focuses on answers based on empirical facts embedded in numerical Linked Open Data. The portal is backed by services addressing data extraction and semantic integration, creating and merging of data sets, and discovery and visual analysis targeting IT laymen.
