To achieve widespread use of the Semantic Web depends on having a critical mass of Web data available with semantic annotations. Since there are a huge number of sources available today without any such annotations, the challenge is how to find and build semantic models for these sources. In this talk I will describe an integrated end-to-end approach that automatically discovers information-producing web sources, invokes and extracts the data from these sources, builds semantic models of the sources, and validates the results by comparing the data produced by the source with the model of the source. These techniques are implemented in a system called DEIMOS, which integrates a diverse set of technologies to completely
