Data mash-ups unleash users from the limit of accessing one dataset at a time, and enable a broader view based on the integrated data. A key challenge to mashing up Data.gov datasets lies in the fact that cross-dataset links are rarely published explicitly by dataset owners, making it hard for users to find related datasets for building mash-ups. In this paper, we show several types of hidden cross-dataset links found in Data.gov and explain how they can be obtained using semantic technologies in Rensselaer's Linking Open Government Data project.
